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.

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)
