An open quarry with an impressive 20m+ central wall and smaller, lower quality walls either side. The main wall offers excellent mileage at f7a and above on generally sound, well bolted rock (but be careful with those large flakes and overhangs!). Pick of the bunch are Lost Contact, Can Boys (both f7a) and Virtual Insanity (F7b). The routes on the short walls to the far left from Beastiality to Terry and June have a carpet of different species of orchids and other rare plants at their base (a very narrow strip of moss adhering to boulders that is easily dislodged). These are not quality routes (understatement!) and as such there must be some thought given as to whether it is worth damaging the plantlife to climb them.
Approaching from Peak Forest pass through Smalldale village and park on the first track leading into the brickworks on the left.
As of June 2019, the lorry park owner has requested that climbers do not approach through the lorry park due to increased usage of the park. Instead go down to the second drive just to the south. Climb over the small stone wall and go through a big black gate into the woods. Cut diagonally through the trees following a vague path to the Crystal Walls.
