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%.

It's well worth the effort to climb to the top of the pass.

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.

Sychnant Pass (Welsh: Bwlch Sychnant, "Dry-stream Pass") in Conwy County Borough, Wales, links Conwy to Penmaenmawr via Dwygyfylchi. Much of the pass is in Snowdonia National Park, and a large area of land within it has been designated a site of Special Scientific Interest. At the bottom is the village of Capelulo, which lends its name to the community of Penmaenmawr. Tough climb from any direction. Well worth for the stunning scenery.

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!
