About this Route
This GPX climbs High Willhays from Meldon by the West Okement valley and returns the same way. It covers 9.9 km with about 386 m of ascent, taking around 3½ to 5 hours. The height gain is moderate, but the upper moor is pathless or faint in places and can be difficult to cross after rain.
From the Meldon Reservoir area, follow the track by the dam and into the West Okement valley. The early walking is clear, with the reservoir and viaduct providing useful landmarks behind. Beyond the main tracks, the route crosses rough grass and peat towards the western slopes of High Willhays. A steady climb reaches the broad summit area and cairn at 621 m, the highest point on Dartmoor. The top itself is rounded rather than dramatic, and mist can make it hard to distinguish from nearby ground.
Return through the West Okement valley by the same line. This GPX stays clear of Yes Tor and does not make the usual two-summit circuit. Tors, military tracks and animal trods create tempting alternatives, so keep checking the route. Expect bog, tussocks and hidden drainage channels; carry a map and compass, and avoid relying on the summit cairn being visible.
The summit is broad and quiet; on High Willhays, navigation matters more than finding a dramatic final climb.

Route Waypoints
Start from the designated parking area near Meldon Reservoir. Check local signs and keep dam and service access clear.
Follow the reservoir track and cross or pass the dam as shown by the GPX. Take care on exposed structures in strong wind.
Continue into the valley on the main track. Ignore paths climbing towards Yes Tor.
The route becomes rougher and wetter as the clear track fades. Note the shape of the reservoir for the return.
Leave the valley line and begin the climb towards High Willhays. Use a bearing if the summit is hidden.
Cross broad grass and peat, avoiding deep channels and saturated hollows. In mist, take a bearing for the summit rather than following faint tracks towards Yes Tor.
Reach the cairn at 621 m. Stop here; Yes Tor is not part of this GPX.
Retrace the moor and West Okement track to the reservoir, checking the turn back into the valley.
Essential Tips
This GPX does not visit Yes Tor. Return by the West Okement line rather than following the popular two-summit circuit.
The upper ground has faint trods, bog and drainage channels. Carry a map and compass and use bearings in mist.
Walk on durable ground where possible and avoid widening waterlogged tracks. Step around deep peat only when it can be done without trampling a wider area.
Follow current parking, dam and estate notices. Operational work can affect paths near the start.
Frequently Asked Questions
How long does it take to walk High Willhays from Meldon Reservoir?
It takes around 3½ to 5 hours to complete the 9.9 km round trip. The estimated time using Naismith's Rule is 2h 34m, but allow longer if conditions are wet or visibility is poor.
Is there a clear path to the top of High Willhays?
No, the upper moor is pathless or has only faint tracks. You'll need to navigate across rough grass, peat, and bog, especially after rain, so carry a map and compass.
What's the terrain like on the way up to High Willhays?
The early walking along the reservoir track is clear and easy. Higher up, you'll cross pathless moorland with bog, tussocks, and hidden drainage channels that can be difficult, especially after rain.
