Devil’s Dyke

Devil's Dyke is a vast, steep-sided valley carved into the South Downs north of Brighton, and this 4.8 km circuit from the hilltop car park descends into the valley before climbing back along open ridgelines with views stretching across the Sussex Weald. The Dyke is the longest, deepest and widest dry valley in the UK, and the scale of the landform is immediately impressive. The 120 m of climbing is concentrated on the return ascent from the valley floor, and the paths follow chalk grassland and well-worn tracks throughout. On clear days the views reach to the Surrey Hills in one direction and the sea in the other.

This is a dog friendly walk with dramatic scenery packed into a short distance. The chalk downland carries distinctive dry, herbal scent, and the constant wind along the ridgelines keeps dogs alert and engaged. Off-lead potential is high across the open hilltop, though livestock graze the valley sides and surrounding downland extensively, so leads are essential where sheep and cattle are present and recall must be reliable on the open sections. The exposed nature of the route means wind can be significant, which most dogs enjoy but owners should be prepared for. There is no water access on the route, so carrying water is important. The combination of scale, views and accessible terrain makes this one of the most rewarding short walks on the South Downs.
