A wonderful spiky summit with fine views to Yr Wyddfa and into Ogwen Valley. The summit itself is a scramble over very large jumbled boulders.

Y Garn is a fine hill, usually climbed from Ogwen Valley by it's West ridge, or as part of the walk along the Glyders range between Elidir Fawr and the Glyders themselves. There is however another way up, the East Ridge, which is a Grade 2 scramble and starts from Llyn Idwal.

Poor Elidir Fawr! It has been bashed about and big lumps knocked out of it at Dinorwic Quarry, it has had a power station built inside it, and has a reservoir for that reservoir almost at the very top. Fortunately when you climb it from Nant Peris you will only see the reservoir, the rest of the damage is ot of sight.

Great tour along the ridge of Crib Goch. Highly exposed in many places and solid scrambling (on mostly good rock) required as most mistakes here will be fatal. Orientation is not too tricky if you follow the polish on the rock, but there are sections with different options and difficulties (especially around the pinnacles). Be aware that the ridge is quite long and you will have to cross it completely in most cases as there is no escape and going back is not any easier. If you are up to the difficulty an amazing experience with great views.

In my view THIS IS NOT A HIKING HIGHLIGHT, but mountaineering. The ridge of Crib Gich is a great scamble, right over the ridge. The rock is pretty solid, but exposure is high in places and any mistake/slipping is probably fatal along most parts of the upper section. You are rewarded with great views and a unique experience.

One of the best climbs / scrambles in the UK by far. Must be done during fine weather conditions. Gloves are a great addition for added grip.

Crib is not for those doing a scramble for the 1st time. Especially in adverse conditions

Winter conditions can make some routes, like Crib Goch Ridge, require specialist mountaineering skills and equipment.
