Eryri National Park has the most dramatic roads in Wales. Llanberis Pass threads between huge rock walls, Nant Gwynant drops to Beddgelert, and the lanes to Bala and Bwlch y Groes climb into real wilderness.
Rocky, twisting mountain roads, frequent tight corners and unforgiving stone walls. Summer traffic and walkers' parking narrow the main passes.

Roads in the Eryri (Snowdonia)
Llanberis Pass
The A4086 through Llanberis Pass squeezes between towering rock faces and boulder fields at the foot of Yr Wyddfa. It is dramatic, twisting and one of the most photographed roads in Wales.
Ogwen Valley
Thomas Telford's A5 runs through Capel Curig and along Llyn Ogwen beneath Tryfan, one of the most striking mountains in Wales. It is a fast historic road with scenery that keeps getting better.
Nant Gwynant
The A498 drops from Pen-y-Gwryd with a famous viewpoint over the Gwynant valley, then winds past Llyn Gwynant and Llyn Dinas to the village of Beddgelert.
Bwlch y Groes
Bwlch y Groes, the Pass of the Cross, is among the highest public roads in Wales. A single-track lane climbs steeply out of the Dyfi valley to a remote summit before dropping towards Bala Lake.
