The North Downs Escarpment
Hackhurst and White Downs occupy a steep stretch of the North Downs escarpment west of Dorking, where the chalk ridge drops sharply to the Weald below. The combined site covers 457 acres and is designated a Site of Special Scientific Interest for the quality of its chalk grassland, secondary woodland, and scrub. The Pilgrims' Way – the ancient route between Winchester and Canterbury – crosses the downs, as it has done for centuries.
The chalk grassland here is among the richest in Surrey. The short, flower-studded turf supports horseshoe vetch, wild thyme, rock rose, and several species of orchid, including the nationally uncommon man orchid. Hackhurst Downs holds the only sizeable stand of juniper on the North Downs – a slow-growing evergreen that has declined sharply across southern England.
Butterflies and Invertebrates
Forty species of butterfly have been recorded on the downs, a remarkably high count that reflects the diversity of habitats. Adonis blue, chalkhill blue, Duke of Burgundy fritillary, marbled white, brown hairstreak, and silver-spotted skipper are all present. The invertebrate fauna is equally rich, supported by the warm, south-facing slopes and the variety of flowering plants.
Walking the Downs
The downs are crossed by the North Downs Way and several local footpaths, making them accessible from Gomshall, Abinger Hammer, and Ranmore. The terrain is steep in places, with the best views from the escarpment edge looking south across the Low Weald. A wartime pillbox on Hackhurst Downs provides a good vantage point. The downs link naturally to Ranmore Common to the east and the Abinger Roughs to the south, allowing longer routes across the landscape.
