This route is a little bit of an outlier and not as good as Cyfrwy Arete Variation (p.260), but fun nevertheless. It tackles the reddish slab from the shores of Llyn Cau. The initial slab is tricky but not really above grade 2. However gear is a hard to find. Above the scrambling is exposed but never desperate and the rock is interesting.
1) Climb a left- trending ramp-line to a crack.
2) Ascend the crack to gain the main slab and climb it more or less direct to a shoulder.
3) From a boulder, move out on the left to gain the continuation of the slab.
4) Follow the best of the rock up a series of slabs linked by heather to a final steeper slab where the real scrambling ends.
5) Now pick your way up heather until you reach a more grassy hillside where the angle starts to ease, from here start to pick your way diagonally across the hillside to the summit.
6) Just before the summit you pass over or around a rock formation of pillow lava and onto the final scree-strewn summit.
Descent - Either descend the Cwm Cau Horseshoe or reverse its approach over Crag Cwm Amarch. © Rockfax
