These are a number of spots to park over on the eastern side of Dartmoor, to the northeast of Haytor, on Trendlebere Down. There are more spots than are indicated on my map. Especially on the road to the east that passes Reddaford Reservoir, along this road however is the largest of the spots, with a large car park right in the middle of Trendlebere Down. There are also a number of spots on the higher road under Black Hill which leads to Haytor Down. Altogether these spots provide a decent amount of parking on the edge of the busy area around Haytor and Hound Tor.
