The A498 follows Nant Gwynant from Beddgelert up to Pen-y-Gwryd, 7.1 miles of narrow valley road through Eryri with parked cars and walkers at the trailheads.

The A498 follows Nant Gwynant past its lakes with Snowdon’s southern flanks rising above, one of Eryri’s most beautiful drives. It is narrow with walkers and parked cars at the trailheads, so take it slowly and let the views come to you.

If this were in the Alps you’d never hear the end of it. Instead it sits quietly in Wales, which somehow makes us love it more.
