Lake Vyrnwy Walks and Cycling

11 miles (18 km)

Follow the lakeside cycle lanes around this lovely reservoir on this circular ride in Powys. The country lanes around the water are flat and well maintained so this is a farily easy waterside ride. It's a lovely area with the lake surrounded by hills and attractive woodland. You can hire bikes at Llandwddyn at the southern end of the water.
This route starts from the visitor centre near the village of Llanwddyn and the impressive Vyrnwy Dam. You then follow the B4393 around the water for about 12 miles.
The whole of this route is probably more suitable for cyclists but walkers can enjoy the reserve too. There's nice paths at the southern end of the water near the visitor centre, including a sculpture trail. There's also woodland trails on both the western and eastern side of the lake. At the northern end of the lake you will find the beautiful Rhiwargor Waterfall. There's a nice track running along the Afon Eiddew to the spectacular waterfall. At the southern end you can pick up the Glyndwr's Way long distance footpath. The waymarked trail can be used to explore the nearby Dyfnant Forest.
The area is also a RSPB nature reserve so you can look out for a variety of birds including great crested grebes, dippers and buzzards. There are bird hides around the lake.
You can follow the trail using the google street view link below.

Head south from the car park and you can explore the expansive Dyfnant Forest. Our circular walk starts from the lake car park and takes you along some of the footpaths and bridleways in the coniferous woods. The forest is also good for mountain biking with a number of wide off road trails to try.
The lake is also not far from another major highlight of the area at Pistyll Rhaeadr. These wonderful falls are regarded as one of the Seven Wonders of Wales. There's a nice walking trail to follow through the gorge with a lovely waterside tea room to visit too. The falls are located about 7 miles north east of the lake.
To the south of the lake you can pick up the Ann Griffiths Walk at Pont Llogel. The 7 mile trail is named after Wales' foremost female hymn writer. You'll pass locations associated with her life including her home at Dolwar Fach and her memorial chapel at Dolanog.
Just a few miles to the north east there's the worthy village of Llangynog. The attractive settlement sits in fine scenic spot at the confluence of the Rivers Tanat and Eirth. From here you can explore the Tanat Valley and Berwyn Mountains.
The circular Bwlch y Groes Cycle Route passes the northern end of the lake. This challenging climb takes you to the second highest public roadmountain passinWales,with a summit altitude of 545 metres (1,788ft).
