First, a somewhat adventurous ride on the single track to the parking lot, which costs £5. The easy loop around the lake is very beautiful and relaxing – the sheep roam freely, but they keep their distance. Dogs must be on a leash, of course, but that's not a problem. Enjoy it – and if you're up for more, go for a longer loop. There are a few tables and benches above the parking lot for your picnic. You won't find any litter baskets, so you'll have to take them with you – which is perfectly fine, as it's a nature reserve. Highly recommended.

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.

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. (DOLGELLAU.uk)
