Top gate leads down to the two waterfalls, unfortunately there has been extensive damage to the path by falling trees after recent storms. The gate is closed and signs in place..... No idea how I managed to get the shots of the waterfalls. it's at your own risk.

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.

Llyn Crafnant is a lake that lies in a valley in Wales where the northern edge of the Gwydir Forest meets the lower slopes of the Carneddau mountains and, more specifically, the ridge of Cefn Cyfarwydd. The head of the valley offers a profile of crags which are silhouetted at sunset. The Forest Park guide (2002) states that "the (view along Llyn Crafnant) is one of the most breathtaking views in all Snowdonia" Crafnant takes its name from โcrafโ, an old Welsh word for garlic, and โnantโ, a stream or valley. Many visitors walk there from the village or from the neighbouring lake of Llyn Geirionydd, which runs parallel to it, but a mile distant, the two being separated by Mynydd Deulyn โ โmountain of the two lakesโ. The lake can also be reached on foot from Capel Curig.
