Llyn Cwm Bychan is approximately ½ mile in length, 520 feet above sea level with a maximum depth of about 18 feet. It lies at the head of a valley about 4½ miles north-east of the village of Llanbedr. A very narrow and winding lane follows the scenic Afon Artro valley, finally running alongside the lake to Cwm Bychan farm, which has a small parking (honesty box) and camping area (no facilities).
It's a good choice for a day out; the Rhinogs and the Roman Steps are within walking distance, and there are numerous smaller lakes high up in the mountains.
