Lanhydrock to Respryn circular walk
  1. Facing the fence to the cricket ground, bear left to follow along the fence (in the direction indicated by Cycle Trail signs) to the information point at the top corner of the car park near the fence. Turn right and follow the white arrows on an orange background to the entrance to the Skills Area then keep right along the path through the trees until it ends at a red gate leading onto a lane.

    Amongst the broadleaf trees growing in Hart Wood are beech, which drop nut casings onto the forest floor in early autumn.

    The word "beech" is thought to have the same origins as "book" as beech (most probably the bark) was used as a writing material in which to carve runes by Germanic societies before the development of paper. This is still apparent in modern German where the word for "book" is buch and "beech tree" is buche.

  2. Go through the gate and turn left onto the lane. Walk a short distance to a crossroads and cross the road carefully to the track opposite. Follow the track until it splits three ways.

    The woodland has a lot of broadleaf trees which can produce some nice colours in the autumn.

    A normal healthy leaf contains chemicals which are both green (chlorophyll) and yellow (carotene). If chlorophyll stops being produced, leaves turn yellow. This happens when sunlight is reduced either temporarily (e.g. accidentally leaving something on the lawn) or in autumn when there is less sunlight overall and when cold temperatures also speed up the breakdown of chlorophyll.

    The growing conditions for trees varies from year to year (e.g. there might be a drought one summer). The "bad years" and "good years" are reflected in the widths of the rings. The pattern of good and bad summers is the same (more-or-less, depending of the location) for every tree so this forms a calendar - the known sequence of wide and narrow rings can be used to assign an exact year to each ring. This can also be done with dead and even fossil trees both to date them and get an idea of what the climate was doing at the time.

  3. Where the track splits, keep right and follow the woodland track until you reach a path departing from the right marked with a waymark post with a yellow arrow.

    The National Cycle Network is coordinated by the charity Sustrans. It began with one route in Bristol in 1984 and now consists of around 15,000 miles of signposted cycle routes known as National Cycle Routes. These each have a number and are constructed using a combination of roads typically chosen to have light traffic and some traffic-free tracks which are open to cycles.

  4. Turn right onto the path indicated by the yellow arrow on the waymark to the far side of it and follow this through the woods until you reach a cycle track crossing the path at some boulders and a post marked Hart Trail.
  5. Continue ahead on the path marked with a no cycles symbol and follow it until it ends at a red gate onto a lane.

    From Roman times, holly trees were planted near houses as it was believed to offer protection from witchcraft and lightning strikes. There is some scientific basis for the latter at least: the spines on the leaves can act as lightning conductors. The sharp points allow electrical charge to concentrate, increasing its potential to form a spark.

  6. Go through the gate onto the lane and turn left. Walk a short distance to a cycle route 3 sign opposite another red gate on the right. Go through the gate and cross the cycle track to the path opposite. Follow the path along the stream until you reach a pair of footbridges by the river.

    The surfaced cycleway leading from Bodmin Parkway station to Station Lodge near Respryn Bridge was originally created in 1864 for a horse-drawn carriage to connect Lanhydrock with the railway. Known as Station Drive, the ornamental carriageway includes fantastic conifer specimens including giant and coastal redwoods, Douglas fir and Monterey pine.

  7. Cross the footbridge on the right and follow the path along the river to a gate.

    The Fowey is used as a conduit for the public water system to feed water from the Siblyback and Colliford reservoirs on Bodmin Moor down to Restormel where it enters the water mains. The increased demand for water from summer visitors has the effect of buffering the river levels in the drier months from the reservoirs.

  8. Go through the gate and follow the path to reach a gate into a grassy area containing a car park.

    Moles are solitary except when breeding so a network of tunnels is occupied by a single mole. Moles typically live for around 3 years and when a mole dies, its tunnel network is often inherited by one of its offspring. Thus the expanding estate can be passed down through several generations. In wetland areas where there is no gradient available to retreat uphill from rising water, moles construct a large mound protruding around half a metre above the ground to act as an emergency flood shelter.

  9. Go through the gate and bear right to a wooden walkway next to the large sign in the corner of the parking area.

    Respryn Bridge is a five-arched mediaeval bridge constructed of granite and rubble spanning the River Fowey at Lanhydrock. The central pointed arch dates from the 15th century; the other arches are more recent. Before this, there was a 13th Century bridge on the site. The place name indicates a ford was here before the bridge, on an ancient trackway between Bodmin and Looe. A chapel was also documented as being located by the river in the 12th Century. In the Middle Ages, chapels were quite common at fords, so the prospective crosser could pray that they were going to make it to the other side, or in the other direction (only, if successful!) give thanks for a safe passage.

  10. Follow the path over the bridge to reach the cycle path by a large tree. Turn left onto the cycle path and follow it past the lodge to reach a lane.

    National Cycle Route 3 runs 338 miles from Bristol to Land's End. The route is a mixture of lanes, byways and some tracks not open to road traffic including the upper section of the Camel Trail from Wenfordbridge to Dunmere.

  11. Cross the lane and follow the drive to reach a junction of tracks in front of the gatehouse.

    Lanhydrock lies just south of the A30 below Bodmin near Bodmin Parkway station. The Lanhydrock estate originally belonged to the Augustinian priory of St Petroc at Bodmin, but the Dissolution of the Monasteries during Tudor times saw it pass into private hands. It was bought in 1620 by wealthy merchant Sir Richard Robartes, who began building the house in 1630 but died only 4 years later. The building was finally completed in 1651 by his son and the estate remained in the Robartes Family until the 20th Century.

    The Robartes family declined significantly during the First World War, losing the heir who was killed during the Battle of Loos in France whilst trying to rescue a colleague from no-man's land. The estate passed to his younger brother, Francis, who became 7th Viscount Clifden. In the Second World War, the house was used to accommodate evacuees. After the war, in 1953, the house and approximately 400 acres of parkland were given to the National Trust by the ageing Viscount. On the death of his younger brother Arthur, the barony and viscountcy of Clifden and barony of Robartes became extinct. Only one descendant of the family survives, living in a cottage on the estate.

  12. Before the gatehouse, turn left and follow the track to reach a junction of paths with a wooden post with red and purple arrows.

    Due to the steady flow of people buying cakes in National Trust cafés and consequent supply of crumbs, the robins around Lanhydrock are very tame. We encountered a cheeky one in the kitchens pecking at the bread displays for Christmas.

    Robins are able to hover like kingfishers and hummingbirds and use this skill when feeding from bird feeders, which they are unable to cling to.

  13. Follow the track leading ahead (marked with a red arrow) and continue until it forks.

    To your right is the Great Wood of Lanhydrock.

    The Great Wood alongside the parkland at Lanhydrock has been designated as an Important Plant Area by the organisation Plantlife for its ancient woodland and lichens. Trees include beech, oak, sycamore, ash, sweet chestnut, holly and a number of Scots Pine. Since the clearance of invasive Rhododendrons from the Great Wood, fantastic displays of bluebells can be seen in the spring. Lanhydrock is also home to kingfishers, dormice and 12 species of bat.

  14. Keep right at the fork and head to the gateway ahead at a bend in the track.

    Honey made with rhododendron pollen can be poisonous to humans, causing severe low blood pressure and low heart rate if enough is eaten. Rhododendron honey is used in Nepal as a hallucinogenic drug.

  15. Go through the left of the two gates (the one ahead) and follow the track across the field and into the woods until you reach a path departing from the left.

    Tannins are natural preservatives. The reason why red wine keeps much longer than white is that the grape skins that give the red colour also contain tannins. Oak leaves, wood and acorns all contain a high level of tannins. When wine is aged in oak, the wooden barrels release more preservative tannins into their contents.

  16. Keep right to stay on the main track and follow this until you reach a wooden signpost to Lanhydrock House and Respryn river walks.

    The track ahead continues until it eventually reaches the gatehouse at Maudlin, passing the mineshafts of Maudlin mine, now concealed in the woodland.

    The mine at Maudlin was described in 1860:

    36 men, 2 females, and 4 boys employed: total 42. Mineral Owner, Duke of Cornwall. Dues, 1-20th. Depth of adit, 30 fathoms. Depth under adit, 70 fathoms. Workings commenced in 1851. Pumping-engine 36-inch. A water-wheel, 32 feet diameter and 3 feet 4 inches wide, draws up the stuff and stamps it. A good discovery has just been made, and the prospects of this mine are very favourable.
    The works are of very ancient origin, and produced large quantities of copper and tin, principally copper, from huge deposits in connection with the carbona, under large deposits of gossan. These mineral deposits, in their turn, became unbottomed by a second appearance of large deposits of gossan; in sinking through which, to reach the metallic minerals below, the present adventure is being carried on. While sinking through the gossan the returns of minerals are inconsiderable, and expected so to continue until the gossan is again unbottomed.

    ("gossan" is mining jargon for an oxidised area of the mineral lode; "carbona" is a deposit of ore)

  17. Turn right in the direction signposted to Lanhydrock House and follow the track to reach a junction with a pair of granite gateposts on your left and an orange waymark pointing ahead.

    The woods around Lanhydrock provide cover for deer, which you're most likely to see at quiet times when there are no people or dogs around.

    Red and Roe deer are the two truly native species of the six found in the UK and both have pointy, branching (rugose) antlers. The Red deer is the largest of the species and has a characteristic large white V on its backside whereas the Roe deer just has a small white patch.

    The fallow deer was introduced by the Normans and has flat, elk-like (palmate) antlers and an inverted black horseshoe surrounding a white patch on its rear end.

    In the late 19th and early 20th Centuries, three "exotic" Asian species (munjac, sika and Chinese water deer) were introduced. These all have quite rounded ears whereas the European species all have pointy "elf-like" ears.

    Roe deer, Fallow deer and Red deer are all present in Cornwall and the populations of all three species has increased substantially over the past decade, possibly by as much as a factor of ten. There are also a small number of munjac deer, but far fewer than in the rest of England.

  18. Continue ahead in the direction of the orange arrow until you pass alongside Garden Cottage. Continue a short distance further to reach a junction in the track, just past the cottage.

    The Roe Deer is unusual among hoofed animals as the egg is fertilised at the time of mating but then goes into suspended animation for several months - a process known as delayed implantation. This mechanism means that instead of being born in late winter, the young are born in early summer when food is more plentiful.

    In most species with delayed implantation, the mother sends out a hormonal signal to tell the embryo to wake up. However in the case of the Roe Deer, the embryo has a built-in egg timer which sends a chemical message back to the mother that it's time to resume the pregnancy.

  19. Continue ahead from the junction and follow the track through the woodland gardens until it ends at a wooden gate.

    The garden's design relates to the Victorian restoration of the house. It was laid out along mid-19th century lines by George Truefitt, to complement the style of the house and to provide a pleasure ground for the family. The formal gardens include an enclosed forecourt with topiary, based on rows of Irish yews and box-edged rose beds, a parterre also hedged with box and a herbaceous garden enclosed in a circular yew hedge. The picturesque woodland gardens, leading from the formal gardens to the Great Wood, specialise in magnolias, camellias and rhododendrons.

  20. Go through the gate.

    The Stables café and toilets are through the pedestrian entrance to the left.

    To continue the walk, bear right to reach the gatehouse at the main entrance to the house.

    National Trust cafés serve around 4.5 million cups of tea per year which is enough to fill an Olympic swimming pool.

  21. Continue uphill, joining the path that runs alongside the track to reach the ticket office and pass this to reach a pedestrian gate leading onto the lane.

    The first version of the house at Lanhydrock , completed in 1651, had a 4 sided layout around a central courtyard. During the first half of the 18th Century, it was neglected and by 1750 in so much disrepair that demolition was seriously being considered to recover some money in salvage and building materials. In 1780, some restoration and remodelling occurred which included demolition of the East Wing to create the U shape. After this, there was another period of slow decline. Then in the mid 1800s, the house underwent a major rework. Not long after this, in 1881, a fire destroyed the south wing and caused major damage to the central section. After this, the house was rebuilt with the exterior in the style of the original building and the Victorian interior was reconstructed, with the addition of kitchens behind the south wing.

  22. Go through the gate and cross the lane to the path opposite. Follow this to the junction with a sign for accessible parking to the right. You can either turn right here to return straight to the car park or continue ahead to go via the Park café and toilets.

The granite parish church that stands in the grounds of Lanhydrock House predates even the first version of the house: parts of the church date back to the late 15th century, though an earlier church or chapel once stood on the site. The church was restored at the end of the 19th Century, following on from the reconstruction of Lanhydrock House after the fire. The church is dedicated to St Hydroc, a 5th Century Celtic saint, possibly a hermit. Outside the church is an ancient granite cross, reported by one source to be from the 13th century.

Fungi are often most noticeable when fruiting, either as mushrooms or as moulds but their main part is a network made up of thin branching threads that can run through soil, leaf litter, wood and even living plant tissue.

Fungus is the Latin word for mushroom but is derived from the ancient Greek word for sponge since this is what they were thought to resemble. Biologically, this isn't so far off either as fungi are more closely-related to animals than plants.

95% of all plant life on Earth, including trees, relies on a symbiotic relationship with fungi. It is thought that without fungi, land plants could not have developed at all. Fungal mycelium often grows around or actually within the roots of plants and give the plant access to water and nutrients it couldn't otherwise obtain easily from the soil. In return, the plants provide the fungi with sugars produced through photosynthesis.

Ferns evolved a long time before flowering plants and dominated the planet during the Carboniferous period. The bark from tree ferns during this period is thought to have been the main source of the planet's coal reserves.

Fern fronds form in a coil (known as a crozier or fiddlehead) with the delicate tip protected in the centre. As the outer parts begin to photosynthesise, the sugars they produce cause more water to be drawn into the leaf, causing it to expand and gradually unfurl.

Ferns produce 2 different types of leaf (although they often look quite similar). The normal leaves are used for photosynthesis of sugars just like in other plants. Ferns also produce a special kind of spore-bearing leaf which can often be identified from the dots on the underside. In hart's tongue ferns, these are really obvious.

Ferns produce neither flowers nor seeds and rely on the tiny spores for their reproduction which are most commonly distributed by the wind. This allows them to colonise some quite random places such as rocky ledges that heavier seeds might not reach. Since the spores come from just one parent fern, the offspring is a genetic clone.

The spore from a fern doesn't grow into a fern. Instead it grows into an organism resembling a liverwort (i.e. a small green blob). Instead of producing spores, these produce eggs and also sperm which they interchange with neighbouring blobs to get a new mix of genes. The fertilised egg grows into a new fern and so this alternating process of ferns and blobs repeats.

Damselflies are predators similar to dragonflies but are easily distinguishable by the way their wings fold back parallel to the body when at rest whereas the dragonflies' wings are fixed at a right angle to the body. The Damselfly has a much smaller body than a dragonfly which means it has less stamina for flight. Nevertheless, it can hover, in a stationary position, long enough to pluck spiders from their webs.

Male damselflies have two sets of genitalia. At the start of mating a packet of sperm (spermatophore) is transferred outside of the male's body between the two and then passed on to the female who uses it to fertilise her eggs as she lays them. Female damselflies lay their eggs inside vegetation. For some species this is in water plants and the female can swim underwater for half an hour before returning to the surface to breathe. Males often guard the egg laying female to prevent a rival male from sneaking in and replacing the spermatophore with his own.

Damselfly eggs hatch not into damselflies but water-living nymphs which look a bit like a dull-coloured damselfly with a 3-forked tail instead of wings. The tail is actually a set of gills used to breath underwater. When the larva is fully developed, it climbs out of the water on a stem or rock. Its skin then splits open and a damselfly emerges with wings which need to be inflated and dry before it can fly.

Dragonflies were some of the first winged insects to evolve, around 300 million years ago in the "age of amphibians" before the dinosaurs. Fossils of early dragonflies have been found with wingspans of up to two feet across.

Dragonflies are named after the way they hunt, as both the larvae and adults are carnivorous predators. Mosquitoes form a large part of their diet both for adults and particularly for the larvae (nymphs). One dragonfly can eat tens of mosquitoes in a day and an average of over 100 per day has been recorded for the nymphs of some species. It is thought that this is an important factor in keeping the mosquito population under control. Dragonfly nymphs have a massive lower jaw to engulf their prey (a bit like an Angler Fish) and are also able to propel themselves by shooting a jet of water out of their anus.

Their two sets of wings beat out of phase, and the frequency, amplitude and the angles of each set of wings can be controlled. This allows dragonflies to hover in a completely stationary position for over a minute, perform extravagant aerobatic manoeuvres and even fly backwards.

Trout are members of the Salmon family who all have an extra tiny (adipose) fin on their back towards their tail, that most other fish don't have. No-one is quite sure what the purpose is of this fin but a neural network in the fin indicates that it has some kind of sensory function.

The trout that supermarkets and trout farms stock is the Rainbow Trout (which has a red flush along its side) and is native to North America not to the UK. Our native trout is the Brown Trout which has well-defined dark red spots along its sides. You can often make out the spots when you see them lying in pools. Rainbow Trout are often stocked in fishing lakes so do sometimes escape into the wild.

Small trout typically feed on invertebrates whereas larger trout generally feed on other fish but have been known to eat anything of a suitable size unlucky enough to fall into a river. In fact in New Zealand, mouse-shaped lures are sold for trout fishing!

The blackbird is a species of thrush. The name "blackbird" is mediaeval, first recorded in 1486. Since most of the crow family is also black, plus many seabirds, the choice of this particular species for the name is thought to be due to its size. Up to the 18th Century, larger birds such as crows were referred to as "fowl" and the term "bird" was only used for smaller species.

The Old English name for the blackbird was osle and up to the 17th Century this survived as in alternative names for the blackbird ranging from ouzel to woosel. One of these is used in A Midsummer Night's Dream by Shakespeare: "The Woosell cocke, so blacke of hew, With Orenge-tawny bill".

Only male blackbirds are actually black. The females are brown. The difference in appearance between males and females is known as sexual dimorphism and is an evolutionary strategy by the males to get noticed more by females at the cost of decreased chances of survival.

Blackbirds can be found in deciduous woodland, particularly where there is dense undergrowth. In the man-made landscape, hedges provide plenty of dense undergrowth and have consequently become a really important habitat for blackbirds. Moreover, many gardens have such a high density of hedges and bushes that they are able to support ten times the blackbird population versus an equivalent area of their natural woodland habitat.

Blackbirds are one of the most common birds in the UK with a population of somewhere between 10 and 15 million. However, blackbirds were in steady decline from the 1970s through to the mid-1990s. The population has only relatively recently recovered.

Blackbirds begin singing from around the end of January but it is normally the overkeen young males initially - the older, wiser males wait until March, pacing themselves for the singing period which continues into the early summer. Blackbirds have been shown to sing more during and after rain but exactly why is not yet known.

Baby blackbirds usually leave the nest before they can actually fly then hop and scramble through the bushes. Their parents watch over them so don't attempt to rescue them.

Blackbirds in the UK are resident all year round but the blackbirds that live further north (e.g. in Norway) migrate south for the winter. To help with migration and also to avoid being eaten by predators, blackbirds can sleep half their brain at a time. This allows them to get some rest whilst still maintaining enough alertness to fly or spot predators.

The reference in the nursery rhyme "sing a song a sixpence" to "four and twenty blackbirds baked in a pie" is thought to be to the 16th Century amusement (though not for the blackbirds) of producing a large pie which included an empty chamber. After the pie had been baked and was ready to be served, a trapdoor would be cut in the empty chamber and live birds were placed inside which would fly out when the pie was cut open. Live frogs were sometimes used as an alternative.

In the Christmas carol "The Twelve Days of Christmas", the line "four colly birds" is thought to be from 18th Century slang meaning "black as coal" and was a popular nickname for the blackbird. Whilst many people today sing and write "four calling birds", this is thought to be a modern misunderstanding of what was originally written.

Camellias are bushes with thick, glossy leaves (but usually a little shorter than rhododendron leaves). As their similar appearance suggests, they are fairly close cousins of rhododendrons but not as closely related to rhododendrons as heathers are (which appearance doesn't suggest!). They flower in the winter, typically between December and the end of March.

Camellias are native to eastern and southern Asia. The first camellia grown in England was in 1739. Many varieties now popular in Britain as ornamental garden plants are from species collected during plant hunting expeditions in the 19th and early 20th centuries. They were regarded as the ultimate luxury flower in Victorian times.

Tea is made from the leaves of one species of camellia which has been bred for many years to hone qualities considered desirable for tea. However, the leaves of many other camellias can be used to produce a similar beverage and tea from another camellia species is popular in some parts of Japan.

The seeds of camellia plants contain oils. In East Asia this is used by hundreds of millions of people as a cooking oil. In Japan it's used for hair care. It's also used to clean and protect the knife blades.
