Devil's Cauldron is a dramatic natural whirlpool formed where the River Lyd churns through the deepest section of Lydford Gorge, in Devon.

The gorge itself is the deepest in the West Country, and at this end the river thunders through a narrow channel, creating a seething mass of roiling water set within a landscape of ancient woodland.

Visitors reach the viewpoint by descending a series of slippery rock steps cut into the gorge wall.

The site sits at one end of Lydford Gorge, a National Trust property maintained since 1947 and designated a Site of Special Scientific Interest for its complex geology and rare mosses and liverworts.

It is paired with Whitelady Waterfall at the gorge's opposite end, and the two features can be connected via circular walking trails of roughly 1. 5 to 3 miles.
