Excellent connecting ridge between Carnedd Llewellyn and Pen yr Helgi Du. FIne climbing and scrambling routes on the northern side, such as in the Amphitheatre.

The ascent to Crimea Pass from Dolwyddelan is along the A470, which can be a busy route. It's just over 3km long with an elevation gain of 205m, giving an average gradient of 6.6%.

Magnificent and dizzying view! However, prefer to go around in the opposite direction to that indicated. The steep slope is very narrow and steep. Easier to go up than to go down.

This is a proper pass and a good challenge as well. Not ridiculously long but will test you if loaded up. The south face is easily rideable up or down on any bike short of a track bike but the north side is the interesting bit. Mucky and loose after rain and looser and muckier as it goes down. Several gates make way to a ford crossing. Then another, and then another for good measure. The first is the most technical and rockiest, and the last is the longest. Please close the gates!
