Llyn Ogwen to Tryfan Viewpoint

Snowdonia National Park

Dog Friendly Rating: 8/10 A short, spectacular lakeside circuit in the Ogwen Valley with some of the best views of Tryfan's iconic north face available without a full mountain climb.

Llyn Ogwen sits at the foot of the Glyderau range in Snowdonia, with the instantly recognisable pyramid of Tryfan rising to 917 metres directly to the south. This 4.6 km circuit follows the southern shore on a rougher, bouldery path with outstanding mountain views before returning along the easier northern side. The Ogwen Falls at the western end add a further point of interest, and the walk can be extended toward Llyn Idwal with minimal additional effort. The opening section requires some scrambling over boulders but settles into a straightforward lakeside path after the first few hundred metres.

This dog friendly walk packs exceptional mountain scenery into a compact distance. The bracing, clear air carries the cold smell of open water and faint peatiness from the surrounding bog. Dogs can enter the water at several points along the northern shore, and the lake is large enough for proper swimming. Dogs must be kept on leads throughout as required by the National Trust. The rocky terrain and boulder-field section at the start suit confident, sure-footed dogs rather than puppies or older dogs with mobility issues. For mountain-loving dogs comfortable on rough ground, this is one of Snowdonia's most rewarding short walks.
