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 cafe is great either before your walk or after as it’s just a few yards from the car park. (Opposite post office)

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 “Pass of the Cross.”

Bwlch y Groes is the second highest public road mountain pass in Wales, with a summit altitude of 545 metres. Gospel Pass in south Wales is slightly higher. It lies on minor roads linking Dinas Mawddwy, Llanuwchllyn and Lake Vyrnw
