"A lido on the Moor" is how one friend described Crazy Well Pool. When we got there after a thirty minute uphill hike, we found a black, rippling pool surrounded by Dartmoor sky. There was a sense of strangeness, indeed otherwordliness, perhaps because of its isolation and the darkness of its waters. It also has no apparent reason for its existence; no water runs in or out. It was perfect for swimming. Backstroking gave a wonderful view of the larks overhead, and the constantly changing skies.
