Points of Interest/Notes on this walk:

Rhyd Dduis pronounced'r-ee-th th-ee'

The arete up to the summit of Mynydd Drws-y-coed is steep, narrow and quite 'airy' in places. You should only attempt it in good weather and if you have a good head for heights.

The descent from Craig Cwm Silyn into Cwm Pennant is down very steep grass and only recommended in good, dry weather. Further more the climb back out of Cwm Pennant involves over 700ft of ascent across rough grass.
