Why it's Wildland

8.2

Created to supply Liverpool with drinking water, Lake Vyrnwy began taking shape in 1881. Its dam was completed in 1888, and water first reached Liverpool in 1891. The surrounding 11.75-mile perimeter road frames a broad reservoir landscape beneath the pointed straining tower.

A reservoir with a remarkable civic engineering story and room for a full day outdoors: walk the dam, look for birds from the woodland trails and take in the long sweep of water and surrounding hills. Its scale and layered history make it more than a scenic drive.

The experience

Make the dam and its spillway the anchor, then choose a woodland bird trail or a section of the perimeter route. The reservoir is a substantial landscape rather than a single viewpoint; allow time to stop and explore. Swimming is prohibited in the supplied route information.

Things to do

Walk across Vyrnwy Dam

Cross the dam wall and listen for water spilling from the structure; the dam is the clearest place to connect the landscape with the reservoir’s engineering story.

Look for birds on woodland trails

The supplied RSPB listing describes woodland trails where visitors may see or hear pied flycatchers, redstarts, dippers, ravens, buzzards and peregrines.

Explore the paved circular route

An 11.2-mile loop with 134 feet of elevation gain, estimated at 3.5–4 hours. The route source notes road traffic and limited lake visibility on part of the circuit; check conditions and route suitability before setting out.

3.5–4 hours

Pause at Old Village Picnic Site

A picnic site identified as a point of interest on the circular route. Facilities beyond the picnic-site designation are not confirmed.

Verified history

Lake Vyrnwy was created to capture water from the River Vyrnwy for Liverpool’s expanding drinking-water supply. Work began in 1881; the dam was completed in 1888; the reservoir took two years to fill, and water was first supplied to Liverpool in 1891. An official completion ceremony took place in 1910. The pointed straining tower marks where water leaves the lake for its 70-mile journey through the aqueduct. The perimeter road is 11.75 miles long.

Hidden details

Follow the water’s route to Liverpool — At the pointed straining tower, notice the point where water leaves the lake and begins its reported 70-mile journey towards Liverpool.

Look for the dam’s valve towers — Two stone towers on the dam house valves controlling excess water flowing from the base of the wall so the river can flow normally.
