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 Glyndŵr’s Way long-distance trail, as well as the 7-mile (11 km) Ann Griffiths Walk.

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.

Llangower provides access to the lakeside for walks, picnics and bird watching. The stop also offers access to the car park and adjacent toilet facilities provided by the Snowdonia National Park. There is a passing loop and small signal box here which is used on gala days and for the pink timetable to allow trains to pass. A beautiful little picnic area for a stop and a break before cycling them hills again.
