Nothing especially tricky or difficult, as long as you have vaguely "gravel" tyres you'll be fine. Stunning views along the way, I prefer the heading west views but it is pretty both ways.

This is a serene lake located in the Conwy Valley surrounded by forested hills and the rugged landscape of Snowdonia. There's a cafe and fishery further south along the lake which is a lovely place to stop and refuel.
