Butterdon Hill Stone Row is the second longest stone row on Dartmoor after the one at Staldon. This stone row runs for just over 2km starting at Butterdon Hill and ending just after Piles Hill. There are several hundred stones in the row, most of them are small upright stones, standing no more than 0.3m in height. At either end of the row is a large hollowed out cairn on each of the hills. The stones in the row vary in their separation, some are 50 metres apart other are clustered together. At the northern end by Piles Hill there is a double stone row running east to west as part of Butterdon. However despite it being on the map it is tough to find on the ground, with long grass and gorse having taken over.
