Stone Farm Rocks are situated just south of East Grinstead (West Sussex) and sits on the hillside overlooking the Weir Wood Reservoir. The rocks are the closest to London and are owned by the British Mountaineering Council and is also a Site of Special Scientific Interest. 

The height of the rocks here is lower than many of the other sandstone crags ranging between 6m to 8m in height. Bolt belays have been placed at the top of the crag in an attempt to minimise any further erosion. There are no bolts above a small number of routes though so  long slings and static rope is needed. 

There are routes of all grades here, mostly in the low-to-mid grades.  Please note that BBQ's are not allowed on-site, especially on the top of the crags which damage the rock. Please do not climb when the rock is wet or damp.

Due to the rock having only a thin outer layer, the rock is very fragile and can only be soloed or top-roped.  Lead climbing is prohibited and placing trad gear would easily rip out and damage the rock. There is a CODE OF PRACTICE for climbers that should be read before climbing and setting up top-ropes.
