This is a list of Dartmoor tors and hills. Dartmoor is a National Park in South West England that contains many granite outcrops of many different sizes. The main authority (other than the OS map) is "Dartmoor Tors and Rocks" by Ken Ringwood.
The total number of named tors and hills on the moor varies considerably depending on the source. Crossing refers to tors as "These granite masses, of which there are about 170 on Dartmoor". There are at least as many named Hills, Downs, Beacons etc. as well as Rocks used to refer to tors. It is not uncommon for a tor and a hill to share a name, as Tor refers to the granite outcrop (for example Nattor Down), equally, as can be seen in the list above, many names recur. Even the definition of Dartmoor varies between sources, particularly between modern sources and those that predate the national park.
