Bristly Ridge ^{Grade 1***}

This is an absolute classic scramble, the best grade 1 in Wales without any doubt!

Although an approach can be made from Ogwen Cottage via the Cwm Bochlwyd path, the best use of the route is as part of the Cwm Bochlwyd Horseshoe, after a traverse of Tryfan.

From Bwlch Tryfan the ridge can be seen as an obvious buttress rearing up to the summit of Glyder Fach. Follow a scree path rising right then left into a gully. Climb this gully with one rock step to emerge at a path crossing the gully top.
There are two options to gain the ridge proper. The first option is to cross the path and continue straight up the gully. The first major obstacle is an intimidating steep wall. Climb this, first on its right side before traversing left then right (always in the gully) to escape difficulties. Continue up the loose bed and climb a small awkward step to arrive on the ridge.

The second option is easier but perhaps slightly more nerve-wracking, being a bit more sustained. Take the previously mentioned path left by a manmade wall to quickly arrive at the base of Sinister Gully. Climb this and move left where it steepens, before scrambling up to the main ridge. Now on the ridge, scramble upwards with a choice of line and fine views back to Tryfan.

A drop in front signals the approach of Great Pinnacle Gap; descend rock slabs and ledges on the left to enter this. Cross the gap, to the right of the pinnacle and climb a tricky small step, moving slightly left round the back of the pinnacle. Follow a gully right and then either climb a steep groove on the left or continue and then head left (easier).
Back on the crest enjoy the last section of scrambling round small pinnacles (or move right for steep walking) before the ridge merges with the summit plateau. Head across to the summit (after an obligatory photo stop at the Cantilever) before heading down.

The best descent is to scramble down the rocky ridge of Y Gribin (grade 1) to Llyn Bochlwyd where the path can be followed back to Ogwen.
