What is the name of the moor in 'The Hound of the Baskervilles'?

The name of the moor in The Hound of the Baskervilles is Dartmoor. Arthur Conan Doyle places much of the novel in this bleak, open landscape in Devon, southwest England, where Baskerville Hall and the Grimpen Mire are situated.

Dartmoor’s granite tors, fog, bogs, and isolation provide the story’s Gothic atmosphere. The moor also makes the supernatural legend of the Baskerville hound seem plausible, even though Holmes ultimately explains the mystery through criminal deception rather than an actual ghostly creature.

The novel was first serialised in The Strand Magazine from August 1901 to April 1902 and published in book form in 1902. It marked Holmes’s return after his apparent death in “The Final Problem.” Readers sometimes confuse Dartmoor with Exmoor or Bodmin Moor, other famous southwest English moorlands, but Doyle specifically identifies the Baskerville setting with Dartmoor in Devon.
