Description
Description:
- Scramble up the buttress starting where the quartz band meets the path
- Once on top of buttress continue over a rightward rising rib until underneath a distinctive notch in the skyline
- Continue up, cutting through a quartz band until you emerge in Cwm Cnefion
- Head SE across the Cwm avoiding hidden drops and crossing a stream (good place to refill water bottles)
- Move across the loose scree field in a S direction until Tower Rib comes into view (distinctive square shaped ridge in skyline)
- Climb up the ridge until you reach the summit of the Glyderau plateau. Near the end to Yr Gribin ridge.
Descent:
- Option 1: head W to summit of Glyder Fawr and follow path that heads down towards Llyn Y Cwn then head NE following a path that brings you down through Devils Kitchen into Cwm Idwal
- From here follow path around Llyn Idwal back to visitor centre
- Option 2: head N down Yr Gribin ridge
- At base turn in a NW direction to rejoin path around Llyn Idwal and follow it back to the visitor centre.
I recommend carrying an OS map of the area (OL17 scale 1 :25000) I also recommend carrying '50 best scrambles in North Wales' by Garry Smith with in depth descriptions of mountaineering routes Ropes and climbing equipment can be carried but I have done both and it doesn't really make a difference to me.
