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.

Lake Vyrnwys straining tower! Lovely place and gives it that fairy tale vibe. One of my special places is Vyrnwy.

Great view of the Mawddach Estaury and the mountains beyond, including Cadair Idris. The bridge is 850m long and can be windy in the middle.
