Much of central Dartmoor is an uninhabited wilderness almost free of villages farms trees & roads making it outstanding environmental value. From this mass rise Dartmoor's rivers including the Lyd Tavy East & West Dart Bovey Teign Taw & Okement nearly all of which flow southwards to the English Channel. The large numbers of tors that dominate Dartmoor are the remnants of hard masses of granite drastically reduced in size & moulded into their present shapes by millions of years of weatherings. Bowerman's Nose Hound Tor & Haytor Rocks are famous examples included on these walks.
