It's a three kilometres walk from the lay-by at Goat Hill Bridge on the B3358 to the Longstone, the tallest menhir on Exmoor. Formed from a slab of local slate, it measures 3m high by 1.25m wide and 0.25m thick at its base. There is a much smaller, companion stone sharing its hole, known locally as a trigger stone, which is 0.7m high.
The Longstone marks the source of the River Bray. It's a 9ft high, thin but wide piece of slate.
Nearby is the Longstone barrow, 3 stones in a line, and a rectangular structure made up of two standing and two recumbent stones.
Nearby also is the Quincunx, made up of 5 stones: one each at N, S, E and W, and one in the middle.
