Crib Goch is a super “exciting” Grade 1 scramble, but it is important to know your abilities and manage the risks of traversing this amazing ridge. Crib Goch is one of the best ridges of its kind and grade anywhere in the UK. It has great scrambling, with some famous arete sections. On a grade one scramble you will need to use your hands on the rock, and on Crib Goch you will do this often. Traversing the ridge on a sunny day is a marvellous experience; on a cold winter day, or in bad weather, it can be perilous without the appropriate equipment. While often straightforward, Grade 1 scrambles still carry risk due to height and exposure, and they should not be taken for granted, especially in poor weather.

The Llanberis Path is considered the easiest path for climbing Yr Wyddfa (Snowdon), and it's particularly popular for first-timers. It has a very short steep climb in the beginning don't be put off by this, it then has a long, gradual ascent up to the summit, just over 9 miles up and down.

Beautiful hike, too bad it was cloudy at the top. 12.3 km isn't the actual distance you'll be hiking: it's definitely 10 km more because you can't walk a straight line on this path. It's very busy on this trail; there's a queue to reach the top.

If you want to park here, you have to reserve a parking space in advance for 20 GBP. We didn't manage to do it, as everything was fully booked. You can then park in Llanberies and take the Sherpa Bus S1 or S2 to Pen y Pass. The bus runs every half hour. From Pen y Pass, you can then choose the Miner's Track or Pyg Track. Have fun!
