A handful of esoteric sandstone quarrys, documented in the Roots Quarry Life bouldering guide
, Britstol Esoteric Guide (*see below) Also a free Bouldering Topo for Lydbrook Quarrys
Really not worth travelling far for. Better to visit Drybrook, 3 Rocks, Ellwood or Huntsham for a good circuit if visiting. For locals, Lydbrook offers a few low grade gems.
