Llyn Cynwch

Highlight • Lake

Llyn Cynwch acts as both a 'prequel' and 'sequel' to the Precipice Walk, one of the most famous and popular walks in the area with breathtaking views. You'll get a glimpse of the lake if you take the route counterclockwise and you'll see it in all its glory if you finish the walk with a nice, steady stroll along the banks.
Together with the Precipice Walk it is part of the historic Nannau estate and is a working water basin that has supplied drinking water for Dolgellau since 1968. Because it is a water basin, swimming is not allowed.

Llyn Trawsfynydd

Highlight • Structure

An enormous man-made reservoir, Llyn Trawsfynydd originally provided cooling water for the local nuclear power station (now undergoing decommissioning). The lake lies in the west of Snowdonia National Park and is overlooked by several mountains. While a lake with a nuclear power station on its banks might not sound like a wondrous place, Llyn Trawsfynydd is actually exceptionally beautiful.

Cycleways and footpaths have been created around the lakeshore and are well-maintained. With woodlands, nature reserves and wetlands, there’s a lot of animal and birdlife here, as well as Atlantic oakwoods. You can cycle the entire way around the lake thanks to a new trail and National Cycle Route 82 leads you from the north around the eastern side.

A bit muddy after rain but never too bad. Avoids the main road, well signposted.

A circular walk through the historical Nannau estate and along the shore of Llyn Cynwch The Precipice has a fantastic array of qualities. From habitats such as woodlands and meadows to captivating views of Snowdonia’s mountain ranges. The path will take you through part of the Nannau estate which dates back to the 12th century and is steeped in fascinating Welsh history. The route ends on the shores of Llyn Cynwch—a working reservoir that provides nearby Dolgellau with water.
