Craig Yr Ogof (Cwm Silyn)

Climbs 47 – Rocktype Rhyolite – Altitude 550m a.s.l – Faces NW

Crag features
The best crag in this area, with a mountain feel. All multi-pitch routes up to 400ft. There is also an E4, for those interested. Notable for Outside Edge (VDiff), Kirkus's Climb/Route (VS) and Jabberwocky (E2 5c).

Good slabby wall on the right with a steep wall of corners and overhangs and the left with some classic HVS to E2s on it [NWDave 1/05]

Rockfall Warning at the top of Ordinary Route / Outside Edge Route. See BMC website for more details. [Sept 14]

Access notes
From Nantlle on the Rhyd Ddu to Penygroes road (B4418). Continue west and turn left after about 2K on the Llanllyfni road. Turn left again after 1.5K and follow this single track road for another 2K to a gate and park. Walk along the track for 45 min past a lake and a big boulder up a steep hill and you're there.
