Many climbers consider Porth Ysgo the best bouldering venue in North Wales - it certainly has climbing of an exceptional quality, plus the type of dreamy, laid back ambience that heals all known maladies. The rock is a superb coarse-grained dolerite - it is a real joy to climb on, if a little tough on the skin in warm temperatures.
The landings are invariably rocky, in some cases frighteningly so. Team visits, with plenty of pads and attentive spotters should avert any potential disasters.
The nearby Trwyn Talfarach, Bytylith, Porth Nefoedd and Mynydd y Graig offer more boulder opportunities on the same top quality rock.
The southern tip of the Lleyn Peninsula has a remarkably high quota of sunny, rain-free days, but should a passing shower wet the rocks they are very quick to dry, especially if there is a breeze. Year round climbing is possible, although it can get very hot during the summer. Approximately half the problems are tidal; obviously it is better to match your visit with a low tide, but it is entirely possible to have a full session even at high tide.
Follow the signposted turn off from the Rhiw-Aberdaron road and park in the small layby where the road splits. Follow the path down by the stream and descend a grassy slope to the boulder field. An alternative approach can be made from the National Trust car park a little further along the right hand road.
