Is one of your best bets for getting onto real rock outside of London, there is an abundance of sandstone slabs close to Royal Tunbridge Wells and East Grinstead. All of which on a good day is only an 1.5 hour from London (dependant on where you live). Below is a selection of the more prominent crags in East Sussex.


A great guide book for the area is Southern Sandstone which is jam packed full of climbs, routes, grades and other information about the area and you can also check out the UKClimbing crag map for more information on locations, routes and access etc

Stone Farm


Stone Farm is owned by the BMC who bought the area for £100 back in 2001. This small outcrop of southern sandstone is a very good bouldering venue and an enjoyable place to climb due to little crowding, remote location, and picturesque scenery. Typical height 6m. Is often dry, but sadly chipped in places. 

Type of Climbing
Top roping, bouldering

Climbing Outside London -East Sussex

​Harrison’s Rocks


Popular with groups and becoming well worn on the easier routes. All of the climbs are quite short, with the highest at approximately 9m. Most climbs have a ring drilled and set into the rock at the top for setting up a top rope, but some rely on the use of tree trunks for protection, so be warned.

Other Information
Please use soft soled shoes and clean your feet on a carpet sample before climbing. 

Harrison's Rocks is composed of a soft sandstone, which is prone to being worn away. It is therefore important to keep erosion to a minimum.

Top ropes should be set up so that the "sawing" effect of rope movement is kept away from rock surfaces as much as possible.

Bolts at the tops of climbs have been placed to help with this

Car park, toilets and a donation box to help pay for upkeep are all located near the crag.
