The path along the lake is very nice. Part of it is actually a kind of dam you walk on, with a barrier on both sides so you have to stay on the path. Because the dam is elevated, you have a good view of the lake and the surroundings.

Llyn Llywelyn is a relatively small lake, sat with Beddgelert forest. The lake is lined with trees, and sat underneath the surrounding mountains, notably the striking Moel Lefn. Definitely worth stopping to soak in the views, no matter what sort of day out you're on.

Found this lovely back road behind the Llyn Cwellyn with great views of the Arenig Hills. Highly recommend this road rather than using the main road around the lake.
