Secluded; surrounding woodland may keep it damp after rain. Plenty to entertain the VS-HVS climber - including the arêtes near the entrance which are sunny and dry quickly - and some three-starred E4+ routes; the longest up to 23m.
Very dirty rock, lots and lots of moss so take a brush and visit in a dry spell. Will improve with traffic.
M4 junction 36, take the A4061 (Bryncethin to Blackmill) road. In Blackmill turn R onto A4093 (signpost Tonyrefail) just after Ogmore Junction pub. Head uphill to Glynogwr, and there turn L between village church and school, into steep narrow lane. Park at the bottom after passing ford.
Alternatively turn left into the housing estate at the bottom of the hill,drive through it then follow a lane to the parking spot by the ford.
Walk into forest, following track (upstream), over a gate; at junction with road turn R and almost double back on yourself. Walk up the path 20 meters and at graffitied trees turn L onto small path to the main rift of the crag. Takes approx 25 mins from car park.
The venue is an Site of Special Scientific Interest, mainly on account of the ferns that grow here (including some rare tiny varieties of "filmy ferns"). No gardening or route cleaning are permitted and it is a criminal offence to do so without formal consent from Natural Resources Wales. There are also protected bat roosts in the vicinity.
