Llyn Cowlyd
The Carneddau range of mountains encompasses a number of lakes in its deep valleys including bleak Llyn Cowlyd.
The lake is actually a reservoir, and has a dam at its north east end. Llyn Cowlyd is the deepest lake in Wales at 222' , measures two miles long by a third of a mile wide and is home to Artic Char, a relic of the Ice Age.
Llyn Cowlyd can be accesed by road from Trefriw. The road, however, stops at a gate, which is about a mile from the lake itself, private vehicles are not permitted beyond the gate.
