Rainbows on mountains tend to be a mixed blessing as they are a pretty sure sign that you are about to get wet! However from the photographers point of view they can also signal some great light, with sun mixed in with dark moody clouds. This was the view from near the summit of Cnicht - otherwise sometimes called the Welsh Matterhorn due to its pointy appearance from the village of Croesor. To the right of the picture is Moel Hebog which rises steeply above the pictuesque village of Beddgelert.

A fine rocky and in places narrow ridge, and you will often have it all to yourself!

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.

The routes accessed from Pen-y-Pass, such as the Crib Goch scramble, also offer extreme mountain experiences.

Can I bring my dog to the mountain passes around Llanfrothen?

Dogs are generally welcome on most public footpaths and bridleways in Eryri (Snowdonia) National Park, including many mountain passes.
