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!
