An impressive icefall, almost 100m in height and home to two of the most coveted ice routes in North Wales: Cascade (WI5) and Central Icefall Direct (WI6). Together with the Devil's Appendix in Cwm Idwal, these two routes make up the "Big Three" of Welsh ice climbing. Once word gets out that the ice is in condition, don't expect to be the only ones at the crag!
The relatively low altitude means a prolonged cold spell is required for the routes to form, but these conditions are achieved most winters. The North aspect helps to preserve the ice once it has formed, but an early morning ascent is normally advisable to get the best conditions before any melting occurs.
Park in the Llanberis Pass, somewhere between the Cromlech boulders and the Ynys Ettws hut (the hut car park is private and reserved for Climbers' Club members). Walk up a path on the South side of the pass up Cwm Glas Mawr, roughly following the stream until you see the icefalls on your left.
