About Llyn Crafnant

Llyn Crafnant

Gateway to one of the finest views in North Wales
Llyn Crafnant is a 3/4 mile-long lake (well, reservoir actually) that lies in a beautiful valley where the northern edge of Gwydyr Forest meets the lower slopes of the Carneddau mountains and, more specifically, the ridge of Cefn Cyfarwydd.

The head of the lake offers what could be regarded as one of the finest views, across the lake to the mountains above, in North Wales.

Crafnant takes its name from “craf”, an old Welsh word for garlic, and “nant”, a stream or valley. Even today the valley of Afon Crafnant smells of wild garlic when it flowers.

We have a car park with toilets just before the lake itself. There is a private lakeside café (open from Easter until late summer) where you can  hire boats. Private boating and swimming is not permitted.

Try the two waymarked forest walks from here.


How to get there:

Llyn Crafnant is in Gwydyr.
You can reach the lake by car from Trefriw in the Conwy valley, though many visitors walk there from the village or from the neighbouring lake of Llyn Geirionnydd, which runs parallel to it, but a mile away. The two lakes are separated by Mynydd Deulyn – “mountain of the two lakes”. Walkers can also approach the lake from Capel Curig.
Take the B5106 from Conwy or Betws y Coed to Trefriw, then follow signs for Llyn Crafnant.
