In reply to John Mulhern:
4 official ones that I know of.
2 in Nant Peris, opposite the Vaynol Arms; Pritchard farm and Cae Gwyn ( 01286 870 718). There is now a cafe and small shop in nant peris.
1 further up the pass in gwasnadant ( sp). This is actually run by the people who own the vaynol arms. Be warned, it's tiny.
1 next to the CC hut, opposite carreg wastard.
and wild camping along the pass.
