Llyn Cynwch acts as both ‘prequel’ and ‘sequel’ to Precipice Walk, one of the most famous and popular walks in the area with breathtaking views as you walk along its narrow track 800 feet above the Mawddach Valley. You get a glimpse of the lake as you take the anti-clockwise route and you get to see it in all its glory as you finish the walk with a nice steady stroll along its banks.

It’s definitely worth a trip even if you aren’t doing Precipice Walk as it’s a gentle, flat, peaceful circular walk and great for young children and dogs, although be careful of the water as well as sheep and lambs that roam the path. It’s also one of the top fishing spots in the area and is run by the Dolgellau Angling Association.

There is a large car park with toilets nearby (Coed y Groes), which adds to its popularity, so the car park can be full on sunny holiday weekends.

Along with Precipice Walk, it is part of the historic Nannau Estate and is a working reservoir that has provided the drinking water for Dolgellau since 1968. As it is a reservoir, swimming is not allowed.
