Grid Reference: SH 68654 61856

Parking and Approach

Follow the access road to Ffynnon Llygwy as for Craig yr Ysfa to the leat or watercourse which traverses the hillside, and follow this to a footbridge just before Afon Llugwy; then take a direct line to the boulder slopes below the crag, about 30 mins from the road. 

On no account should the private road to the farm at GlanLlugwy be used. Moreover, the access road serves both the farmer and the Mountain Rescue teams -- therefore, do NOT park in front of the locked access gate. Under no circumstances use either roads for access. Parking should be either payed at Gwern Cof Isaf or further up the valley below Tryfan bach. 

Area information

A wide range of cliffs - mainly traditional and multi pitch inc. the popular Llanberis Pass, Idwal Slabs, Clogwyn du'r Arddu and Cwm Silyn cliffs, but also outlying outcrops such as Carreg Alltrem. Many crags are on CROW access land - but not all especially some of the outcrops which lie on private enclosed land. Most of central Snowdonia is both designated an SSSI and also is an European Special Area of Conservation on account of the upland habitat and associated geology and plants found here.
