The Berwyn Mountains stretch all the way from Llangollen in the east, along the Dee Valley, to Bala in the west.
The highest peak is that of Cadair Berwyn at 830 metres but there are 24 peaks above 600 metres (2000 feet).
They are a haven to wildlife and the moorland tops provide habitats for curlews, merlins and red kites,
while the streams and rivers of the valley play host to dippers, the occasional kingfisher, swallows and dunnocks.
It is also the home to some rare plants. It is a landscape that both opens up to breathtaking vistas and hides intimate corners. Waterfalls, cliffs, moors, burbling streams and wildflower-dotted fields - the Berwyns have these and more.
There are two main walks, the North Berwyn Way and the Dee Valley Way.
