We’ll be staying in the Caseg Fraith hut, near the top of the pass between the Llugwy and the Ogwen Valleys in Snowdonia, 3.5 miles north-west of Capel Curig on the A5, beneath Tryfan (see our Tryfan webcam).
It is a large hut with electric cooking, electric lighting, electric heating, foam mattresses, running water, flush toilets and two showers.
