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.

A great place to take in a view of east Eryri and the Carneddau range with easy access. See Tal y Fan in the foreground and beyond it Drum and Carnedd Y Ddelw and on even clearer days Carnedd Gwenllian

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.
