Heather moorland, woodland, farmland, rocky streams and a large reservoir attract a wide variety of wildlife to this reserve set at the southern end of the Berwyn mountains. Dippers and kingfishers nest by the lake and rocky streams, while ravens and buzzards can be found on the moorland and pied flycatchers and redstarts can be seen in the woodlands in summer. Lake Vyrnwy is popular with both birdwatchers and families alike.
