The Aran Hills form a north-south ridge extending 14km from the shores of Bala Lake to the sleepy village of Dinas Mawddwy, nestling between hills at a confluence of the River Dovey in southern Snowdonia. The central part of the ridge remains above 800m for more than 2km and reaches up to 905m on Aran Fawddwy, one of the more interesting County Tops.
