Cwm Dyli

Bouldering

A very beautiful and secluded spot with many excellent problems, generally good landings and little chance (once off the main path) of meeting anybody, save for the odd disorientated Snowdon bound walker. No, just you, the boulders, the towering back drop of Lliwedd and your own personal cloud of midges.

The rock is compact rhyolite, generally sound, although the occasional breakage should be expected.
Other interesting bouldering venues in the same area include the impressive Mallory Boulder (seen to the left of the Miner’s track running over to the Ogwen Valley from the Pen y Gwryd hotel) and the few dolerite blocks situated on the hillside on the opposite side of the road to the Pen y Gwryd.

Conditions:

The boulders have a sunny aspect and are quick drying. During the spring, summer and autumn good conditions are common. That said they are situated within the Snowdon horseshoe so relatively high rainfall should be expected. During the winter months it will often be too cold (or snowy) to boulder here.

Approach:

From the Pen y Pass car park walk along the Miner’s Track until the first big bend has been turned. The boulders lie below in the meadow beneath the Craig Aderyn. Descend the tussocky hill slope, crawl underneath the hydro electric pipe, and cross the bog to reach the boulders.
