Really good place to ambush people and the river makes them vanish without a trace.

Thought to have been a key defence for the Iron Age Catuvellauni tribe against the invading Romans, Devil's Dyke is an impressive earthwork to the east of Wheathampstead. At 49 feet (15 m) deep, 131 feet (40 m) wide and 1,500 feet (460 m) long, it would have been a huge undertaking when constructed. This scheduled ancient monument is a delight to explore all year round. However, May is perhaps the best time to discover its charms, when the ground is carpeted by bluebells.

There are some nice trees on this path but the Great Oak is further along, past the Orangery, you get a decent view nearby overlooking the west side of Panshangar. Some of it has been newly opened to make for a longer circular walk.
