The biggest sandstone crag in the South East, a wall of weathered rock in birch woods near Groombridge, laced with climbing routes
Harrison’s Rocks is the largest of the Southern Sandstone outcrops, the low rock walls that break the surface along the Kent and Sussex border. It rises to something like ten metres at its highest, tucked into birch woodland, with hundreds of named climbing routes along its face — a training ground for generations of climbers, now looked after by the British Mountaineering Council. The sandstone is soft, so people climb here on top-ropes rather than leading, and by long-standing agreement no one climbs it when the rock is wet, which crumbles the holds. Even if you’re not climbing, it makes a good short walk in the High Weald, with Eridge Rocks and other outcrops close by and Groombridge just up the lane.
