Sychnant Pass (Bwlch Sychnant)

Highlight • Mountain Pass

While the hills above Bwlch Sychnant are not high by Eryri's standards, their steepness lends the pass a drama all of its own. This is the most northerly mountain pass in the national park, connecting Conwy to Penmaenmawr. A clutch of summits can be ascended from the road, including Alltwen, Penmaen-bach and Mynydd y Dref (Conwy Mountain). Each provide excellent views towards Great Orme and south towards the high Carneddau.

The footpaths here reveal glorious views down towards Conwy and its brooding 13th-century castle. On a good day, you can see for miles across a vast swathe of Snowdonia, while it's easy to hike up to the summits of Alltwen, Penmaen-bach and Mynydd y Dref (Conwy Mountain) from here, for some truly excellent panoramas.
