Lake Vyrnwy, Water reservoir in Powys, Wales

Lake Vyrnwy is a reservoir in the Berwyn Mountains in Powys, Wales, with a stone wall reaching 44 meters (144 feet) high and covering about 4.5 square kilometers (1,100 acres). The area offers routes for walking and cycling, sailing facilities, and zones for watching birds.

The valley was flooded between 1881 and 1888 to supply drinking water to Liverpool. The old village of Llanwddyn was completely removed and rebuilt at a higher location.

The name comes from Llyn Efyrnwy, reflecting the Welsh language of the area. Visitors find a park with carved wooden figures and artworks along the paths, placed among the trees since the mid-1990s.

The paths around the lake work well for walks and bike rides, even with changing mountain weather. Most trails are easy to follow, but visitors should prepare for sudden shifts in conditions.

A Douglas fir tree nearby once held the record as the tallest tree in the country, measured at just under 64 meters (210 feet), until a storm damaged it. The area still draws visitors looking for tall old trees.
