April 12, 2026, View of the Valley from Bwlch y Groes

The climb up to Bwlch-y-Groes from Llanymawddwy is a tough one. It is about 3.4 km long and has about 387 m of vertical ascent to get to the gap at 546 m above sea level. You will have an average gradient of 11.3% to grind away at, but you will be rewarded with fantastic views north and south.

This is a nice spot to relax and enjoy the pretty settlement of Pontrobert on the River Vrynwy. Pontrobert features on the GlyndΕ΅r’s Way long-distance trail, as well as the 7-mile (11 km) Ann Griffiths Walk.

Bwlch y Groes (Pass of the Cross) is one of the highest public road mountain passes in Wales. The views from the top of Bwlch y Groes are stunning with views across the Dyfi valley and Cadair Idris. This 17 mile breathtaking route lies on minor roads linking Dinas Mawddwy and Llanuwchllyn in the heart of the Snowdonia National Park and Lake Vyrnwy. The route was part of the pilgrim's route from North West Wales to St David's in South Wales. A cross, which is humble in appearance, is not on a map. It can be found just below the summit at the junction of the road that leads down from Lake Vyrnwy. It was placed on the route as a symbol of faith and strength comforting travellers since medieval times. Cycling the route is definitely not for the faint hearted!

This extraordinary climb is in the northwestern section of Wales in the Snowdonia mountain region. This is the highest paved road and hardest bike climb in Wales. Bwlch y Groes means β€œPass of the Cross.”
