Woodhall Park's rolling countryside is home to a Grade I-listed mansion, ancient trees, a beautiful lake and the River Beane. Created in the 18th century, the park is contained within a 4-mile (6.5 km) wall and is largely unchanged since its creation. Nature conservation projects, forestry work and farming also take place on the estate.

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.
