Alwen Reservoir and its close neighbour Llyn Brenig are large bodies of water, almost completely surrounded by conifer forests. Two excellent cycle routes exist here, with the opportunity to link them for a more involved excursion.
The Alwen Trail follows an 11km way marked circular route around the Alwen Reservoir. A series of forest tracks and paths trace the reservoir shore, mostly in woodland but with view points and picnic spots along the way. There is a particularly charming section which follows the water’s edge. Look out for the various illustrated panels which provide information on local wildlife, culture and folk tales.
The circular route around Llyn Brenig is longer (15km) but just as good. The route has a similar mix of wooded trail and more open shore line sections, plus the impressive Brenig Dam. There are also a number of excellent picnic spots, plus public toilets at either end of the lake. The visitor centre near the dam has an adventure playground and café; you can also hire bikes here.
If you fancy a bigger challenge, why not try the Two Lakes Trail, which links both cycle ways in a 22.5km loop.
There is plenty of parking space at the visitor centre close to the Llyn Brenig dam. There are also three other car parks at points around the Brenig Trail. There is a car park by the Alwen Dam at the southern end of the Alwen Reservoir.
