The full report

From railway history to open moor

The Granite Way provided an easy beginning, but the route soon exchanged smooth tarmac for boggy ground, steep valleys and the unmistakable winter character of Dartmoor.

Setting out from Okehampton

I began at 9.00am from Okehampton Railway Station and joined the Granite Way, a well-maintained tarmac trail shared by walkers and cyclists. The route follows the former railway line, with reminders of its industrial past still clearly visible.

After approximately 2.5 miles, I reached Meldon Viaduct. Built in 1874, the impressive wrought-iron structure now provides a superb viewpoint across the valley. The Meldon Reservoir overflow could be seen in the distance, with High Willhays rising beyond it.

Leaving the Granite Way

At around the four-mile point, I left the Granite Way near Prewley Farm and followed a grassy cross-country trail towards Sourton Tor. The change from smooth tarmac to open moorland immediately gave the walk a very different character.

The climb to the 440-metre summit was steady but manageable. At the top, I stopped for a cuppa and a snack while enjoying wide views across North Dartmoor, with Meldon Reservoir nestled in the valley below.

Corn Ridge and Branscombe’s Loaf

From Sourton Tor, I continued across the open moor towards Corn Ridge and Branscombe’s Loaf, which stands at approximately 537 metres. The ascent became more demanding as the ground grew increasingly boggy.

Patches of light snow and frozen puddles remained from the winter weather, adding an extra challenge—and a useful reminder that apparently solid ground on Dartmoor occasionally has other ideas.

Down to Shelstone Tor

The next stage involved descending into a steep valley towards Shelstone Tor. Some sections were particularly sharp, so I occasionally followed a longer, winding line to avoid the steepest ground. At the tor, I stopped for another break and enjoyed hot soup and something to eat. With the temperature dropping, the warm soup was especially welcome.

Meldon Reservoir and the return

From Shelstone Tor, I descended steeply to the West Okement River. After crossing the bridge, I followed a path beside Meldon Reservoir for around three-quarters of a mile before climbing steadily onto Longstone Hill.

The route then descended towards Red-a-Ven Brook, where stepping stones provided the crossing. A final incline beside the wall near Black Down brought Okehampton Camp into view. A public footpath passes through the camp, offering an unusual final section before rejoining the last half-mile of the Granite Way.

I arrived back at Okehampton Railway Station at approximately 2.20pm, having completed around 12 miles.

Dry, calm and cold—ideal winter walking weather, with just enough frozen puddles and bog to make sure the boots remembered they were on Dartmoor.
The route

Railway, tors and reservoir

A route of two distinct halves: the easy-going Granite Way followed by rougher cross-country walking over North Dartmoor.

Practical information

A long and varied North Dartmoor circuit with an accessible railway-path opening followed by exposed, pathless and boggy moorland.

Distance and time

Approximately 12 miles. I left at 9.00am and returned at 2.20pm, including refreshment stops.

Terrain and difficulty

Tarmac railway trail, grassy moorland, boggy ground, stepping stones and some steep descents. The cross-country section requires confident navigation.

Conditions and kit

Dry, calm and cold, with frozen puddles and light snow remaining on higher ground. Waterproof boots, warm layers and full waterproofs are advisable.

Navigation

Carry an Ordnance Survey map and compass alongside offline digital mapping. Visibility and ground conditions can change quickly on the open moor.

Safety note

This is not simply a railway-path walk. Beyond the Granite Way the route crosses exposed, uneven and potentially boggy terrain, with steep slopes around the valleys.

John’s verdict

Two walks rolled into one

An enjoyable winter route combining railway history, impressive engineering and the wild scenery of North Dartmoor. Meldon Viaduct and Sourton Tor were the highlights, while the boggy high ground and steep valleys provided the challenge.
