There is a little cafe above the main car park for a coffee and cake after the "gift shop" labelled walks. As usual, Komoot makes the walk easier than using signposts - remember to download to the phone app. Kayaking/canoeing around the lake is only possible for about half of it due to a protected bird sanctuary.

A 10/10 piece of road starting just after Dolhendre caravan park. The roads are smooth and winding, with some steep but varied gradients. Keep an eye out for the waterfalls and enjoy the descent heading towards Trawsfynydd: just watch out for the gates!
