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.

Gorgeous area. Be aware the road/trail on the south side (including access to/from Llanymawddwy) are currently closed due to damage from storm Darragh. See https://www.hdcymru.co.uk/our-visitor-sites/lake-vyrnwy/storm-darragh/ for more details.

There is a little cafe above the main car park for a coffee and cake after the "gift shop" labelled walks. As usual, Komoot makes the walk easier than using signposts - remember to download to the phone app. Kayaking/canoeing around the lake is only possible for about half of it due to a protected bird sanctuary.

located in the old square it's a great place to stop for a brake, there's a great amount of outdoor seating either out in the sun or in the shade. With bike racks at hand and a lovely setting it's a good stop off.
