The given coordinates are for the trig point on Easdon Tor which stands at 1,426 feet and has fantastic views in all directions - on a clear day!
You can park in Manaton, North Bovey or there is very limited parking near some of the footpaths/bridle ways that lead to Easdon Down i.e. Barracourt, Luckdon, or just up from Yard.
We suggest you use the clear paths to the trig point and cache rather than cutting across directly due to the abundant bracken growing in the area.
