These mysterious woods are located in the Arun District of West Sussex, next to the village of Clapham. The woods are most well known for paranormal activity including several UFO sightings. They also have some nice public footpaths to follow through the woods. The woods are surrounded by some lovely Sussex countryside and have bluebells growing in the spring. There's parking available at the south western corner of the woods.
To extend your walking in the area you could climb to the hill forts at nearby Cissbury Ring and Chanctonbury Ring.
