This crag is inside an MOD firing range. Look out for red flags. The Defence Estates endeavour to support public access (without compromising public safety and military training) and firing times with 6 weeks notice can be found here; https://www.gov.uk/government/publications/dartmoor-firing-programme
This crag is home to the only Common Raven nest site on Dartmoor. The nests, which are usually large and clearly visible, are protected by The Wildlife and Countryside Act (1981), and to avoid reckless damage to the nest, birds or their eggs during the sensitive breeding period, the BMC advises climbers to avoid routes which pass through, or near, the nests mid-February to mid-May.
