The Crimea Pass (Welsh: Bwlch y Gorddinan) is a mountain pass in North Wales, on the A470 road between Blaenau Ffestiniog and Dolwyddelan connecting the counties of Gwynedd and Conwy.

At its highest point, it is 385 metres (1,263 ft) above sea level, and is sometimes closed in winter because of snow.

[2] In the mid-1870s, Owen Gethin Jones opened the Bwlch Gordduant quarry near the summit of the pass.

[4] It takes its name from the Crimean War which was being fought about the time the road was opened, in 1854.

The construction of the stone walls in the area was carried out by Russian prisoners of war captured at the battles of Inkerman and Balaclava.
