About the walk

If you want to get a 'quick fix' and to experience examples of almost everything that Dartmoor has to offer, but fairly easily and in a relatively short time – then this is the walk for you. Within 10 minutes of the A30 as it races past Okehampton you can get the lot: a tranquil reservoir, a sparkling river and waterfall tumbling though a beautiful tree-lined valley, wide expanses of open moorland, an area of ancient lichen-encrusted oak woodland and a great view of the highest tors on the moor – and all without expending too much effort. You don't have to tramp for miles over inhospitable moorland or get to grips with a compass to get a real feel of the moor.

Black-a-tor Copse

Owned by the Duchy of Cornwall, this is one of the best areas of ancient high-altitude oak woodland in Britain, and was established as a National Nature Reserve in 1996. There is a huge variety of mosses and lichens covering the granite boulders from which the stunted oaks emerge. It makes a wonderful focus for the walk. There are two other areas of upland woodland on the moor – at Piles Copse in the Erme Valley and at Wistman's Wood by the side of the West Dart River just north of Two Bridges. In all three places the oaks have remained ungrazed because the clutter of granite boulders beneath has protected them from the local sheep. Black-a-tor Copse feels little visited and remote – the atmosphere is quite magical.

Dartmoor's highest tors

Dartmoor is basically a huge granite intrusion, pushed up through surrounding sedimentary rocks, formed in the same way as Bodmin Moor in Cornwall and the Isles of Scilly. Where it is exposed to the elements this raised granite plateau has been weathered into giant blocks, creating the tors so characteristic of the area. The highest part of the moor lies in the northeast corner just south of the A30, where it rises to 2,037ft (621m) at High Willhays, seen from this walk. The average height of the moor, however, is around 1,200ft (366m).

Railway stone

Commercial quarrying (originally for limestone) started at Meldon around 200 years ago. A wide range of minerals have been produced here over the years including aplite, used in the production of medicine bottles. The Black Down copper mine was in operation in the 19th century, as was the Hornfeld Quarry, which produced ballast for the new railways in the area. In recent years the quarry produced ballast, roadstone, concrete aggregates and building stone, and sadly closed in May 2011.

Walk directions

Walk up the steps by the toilets, through the gate and go left towards the dam, signposted 'Bridlepath to Moor'. Cross over the dam and go through a gate.

Turn right on a stony track alongside a fence. Note a gate (right) leading to a waterside picnic area. Do not go through the gate but keep ahead where the track bears left, following the edge of the reservoir through a side valley and over a small footbridge. The narrow path bears right above the water and runs along the contours before descending into the broad marshy valley of the West Okement River; the swell of Corn Ridge, 1,762ft 537m), lies ahead.

Pass the small wooden footbridge and take the narrow path along the left edge of the valley, keeping to the bottom of the steep slope. The path rounds Vellake Corner and passes a water gauging station, then broadens and climbs steadily above the river (right).

At the top of the hill the track levels and Black-a-tor Copse can be glimpsed ahead. Follow the river upstream past a waterfall and weir, go left of a granite enclosure, and along the riverbank to enter the copse – a wonderful picnic spot.

Retrace your steps out of the trees and bear right around the copse edge, uphill aiming for the left outcrop of Black Tor on the ridge above. Pick your way through the bracken to gain the left edge of the left outcrop. The right outcrop rises to 1,647ft (502m).

Climb to the top of the tor if you wish; if not keep ahead in the same direction, aiming for a fairly obvious track visible ahead bearing left across Longstone Hill. To find it go slightly downhill from the tor to cross a small stream, then pass between granite blocks marking the track.

The intermittent track runs straight across open moor. Where the Red-a-ven Brook Valley appears below to the right, enjoy the view of (left to right) Row Tor, West Mill Tor and Yes Tor. High Willhays, Dartmoor's highest point, lies just out of sight to the right. The track bears left around the end of the hill, with good views towards the quarry and viaduct, and drops back to the reservoir.

Bear right on the track, then left over the dam and back to the car park.

About the area

Discover Devon

With magnificent coastlines, two historic cities and the world-famous Dartmoor National Park, Devon sums up all that is best about the British landscape. For centuries it has been a fashionable and much loved holiday destination – especially south Devon’s glorious English Riviera.

Close to the English Riviera lies Dartmoor, one of the south-west’s most spectacular landscapes. The National Park, which contains Dartmoor, covers 365 square miles and includes many fascinating geological features – isolated granite tors and two summits exceeding 2,000 feet among them. 

Not surprisingly, in Dartmoor the walking opportunities are enormous. Cycling in the two National Parks is also extremely popular and there is a good choice of off-road routes taking you to the heart of Dartmoor and Exmoor. Devon’s towns and cities offer stimulating alternatives to the rigours of the countryside.
