A radical cliff with a series of impressive multi-pitch trad routes working up through some bewilderingly steep ground. The smooth compact rock, cleaved into alternating slabby and overhanging facets, is initially confusing. Routes can flit from ultra-strenuous to strange and balancey in the space of a single move. The crag is best suited to climbers comfortable in the extreme grades. Even the classic HVS girdle requires equal competence from both climbers.
Hylldrem is always worth a look if the weather closes in elsewhere. Rainfall in this area is considerably lower than the mountain crags a little further north. The crag receives plenty of sunshine and is quite sheltered. It is possible
to climb the girdle in rain, although parts of it might be wet. The crag dries quickly after rain, and the bouldering wall at the right hand end stays dry, even in torrential downpours. Year round climbing is possible, provided there is enough sunshine to warm the rock up.
The crag leans conspicuously over the A4085 Aberglaslyn – Penhyndeudraeth road 1.5km north of Garreg. Park in the small layby opposite the crag just along from the small bridge over the river. A steep path leads up to the right side of the crag where the bouldering wall can be seen over the ‘A’ frame stile on the right, and further paths traverse leftwards across the hillside to the main routes.
