Harrison's Rocks is a series of sandstone crags approximately 1.5 kilometres (1 mi) south of the village of Groombridge in the county of East Sussex. The site is a notable example of a periglacial tor landform developed in rocks of the Ardingly Sandstone Member of the Tunbridge Wells Sand Formation. It is popular with rock climbers, and is the largest of the cluster of local outcrops known by climbers as Southern Sandstone.
Harrison's Rocks is owned by climbers and is managed on their behalf by the British Mountaineering Council with funding from the English Sports Council.
