Just who did what to a goat remains a puzzle to me, so this small and uninspiring tor deserves a cache simply because of its name.
The approach to Dunna Goat could be achieved from several starting points, but all will involve quite an ascent at some point and there are few routes that seem to remain dry year-round. At over 1800 feet above sea level, this area is exposed to everything that the south-west or westerly winds can throw at you, so come prepared for the worst - should you need reminding, this is Dartmoor and the conditions can change rapidly even in summer.
Cache is a 35mm pot in a small clip-lock box. Bring your own pen!
