Devil's Dyke Sussex
Devil's Dyke is a dramatic dry valley on the South Downs escarpment north of Brighton, a great V-shaped combe carved by periglacial processes during the last Ice Age that provides the most spectacular single viewpoint on the South Downs and one of the finest viewpoints in the southeast of England. The open chalk grassland of the dyke slopes and the surrounding escarpment provides excellent walking on the South Downs Way and the views northward across the Weald and southward toward the coast are among the most extensive available from any point on the South Downs.
The chalk grassland of the Devil's Dyke slopes is one of the finest remaining examples of traditional downland habitat in East Sussex, supporting the characteristic community of chalk-loving plants including common spotted orchid, cowslip, stemless thistle and various chalk grassland grasses, and the butterflies associated with this habitat including chalkhill blue, dark green fritillary and marbled white. The National Trust manages the site and the long-running programme of grazing management has restored much of the traditional grassland character that was damaged by the arable conversion of the mid-twentieth century.
The Victorian entrepreneur who built the Grand Hotel above the dyke also installed a funicular railway and a cable car across the valley in the 1890s, evidence of the dyke's long history as a tourist destination for visitors from Brighton. The views and the walking remain the principal attractions today, the funicular and cable car having long since disappeared.
