The valley's formation was traditionally attributed to a fight between the devil and local saints, a legend immortalized in 17th-century folklore.
During the Victorian era, the site featured a funicular railway, a cable car, and a grand hotel to accommodate thousands of day-trippers.
The site contains one of the largest Iron Age hillforts in Britain, covering approximately 40 acres.
It is a designated Site of Special Scientific Interest (SSSI) due to its specialized chalk-loving plant species.
The escarpment is a globally significant location for paragliding and hang gliding due to favorable wind thermals created by the valley’s shape.
During the Second World War, the site was utilized by the military as part of the coastal defense infrastructure.
Devil's Dyke is the longest, deepest, and widest dry valley in Great Britain, stretching one mile in length. Located within the South Downs National Park, the site features steep chalk escarpments formed by glacial erosion and periglacial activity. The valley reaches a depth of 300 feet and offers panoramic views extending toward the Weald and the English Channel. It sits atop the South Downs Way, a historic trail spanning the southern English landscape. Archaeological remnants on-site include an Iron Age hillfort enclosed by significant defensive earthworks. The area supports rare chalk grassland habitats, home to unique flora and diverse butterfly species. The National Trust manages the property, maintaining extensive footpaths for hikers and walkers. The site serves as a vital ecological corridor for local wildlife within the Sussex countryside.

Wear sturdy, grip-soled walking boots as the chalk slopes can be extremely slippery when damp.
Bring binoculars to scan the horizon, as visibility on clear days reaches as far as the North Downs.
Wind speeds at the top of the valley are often significantly higher than in the surrounding valleys; pack wind-resistant layers.
Attempting to descend the steepest sides of the valley near the car park, as these sections are prone to erosion and are technically challenging.
Keep dogs on leads near livestock, adhere to the Countryside Code, and remain on marked footpaths to protect fragile chalk habitats.
