These rocks comprise three separate outcrops, of which two – Jockey’s Wood Rocks and Penns House Rocks – have recorded routes. The other outcrop, Rocks Wood, is low and of lesser interest to the climber (see Other Outcrops). The outcrops lie within an SSSI, which has been designated because the ‘sandrock’ is a nationally rare habitat that supports a rich community of ferns and bryophytes (mosses and liverworts) including many ‘Atlantic’ species, which are uncommon in South-East England. All the outcrops are on private land in the grounds of Penns in the Rocks, and following advice from Natural England, climbing is not allowed.
