Lake Vyrnwy

You should visit Lake Vyrnwy for one of the most beautiful reservoir landscapes in Wales. A dramatic Victorian dam stretches across the valley, while a stone water tower rises from the lake like something from a fairytale.

You can walk through woodland, cycle beside the water, search for waterfalls, watch birds from hides or simply drive around the lake and stop whenever a view catches your attention.

Why You Should Visit

Lake Vyrnwy is ideal when you want impressive scenery without needing to complete a difficult mountain walk. Some of the best views are close to the dam and main parking areas, while longer forest trails lead into quieter countryside.

Families can explore shorter paths and picnic beside the water, walkers can search for waterfalls and viewpoints, and cyclists can follow the road around the reservoir.

Walk Across the Dam

Start by walking across the top of the dam. From here, you can look along the length of the reservoir in one direction and down into the valley in the other.

The dam was completed during the 19th century as part of a major scheme to supply water to Liverpool. Its scale is impressive from above, but you should also look back at the stone wall from farther down the valley.

Take care around traffic because the road crosses the dam and can become busy during weekends and holidays.

See the Straining Tower

The stone tower standing in the lake is Lake Vyrnwy’s most recognisable feature. Its pointed roof, arched windows and isolated position make it look more like a small castle than part of a water-supply system.

The tower was built to draw water from different depths before it began its journey towards Liverpool.

Walk along the dam and nearby shoreline to see how the tower changes against the surrounding hills, clouds and reflections.

Drive Around the Reservoir

A road follows much of the lake and allows you to see the reservoir from several very different angles.

You can stop at recognised parking places for short walks, picnic spots and views across hidden inlets. The full circuit is around eleven miles, but allow plenty of time rather than treating it as a quick drive.

The road is narrow in places and is shared with cyclists, residents and other visitors. Drive slowly and avoid stopping where you could block traffic.

Explore the Woodland

Forest trails lead away from the lakeshore through mature woodland, streams and steep-sided valleys.

Some paths are short and well surfaced, while others climb onto rougher ground. Waymarked routes make it easier to choose a walk that suits your time and energy.

Listen for woodland birds and watch for changes in the trees as you move away from the open water.

Find the Waterfalls

Several streams tumble down from the hills around Lake Vyrnwy, creating small waterfalls and cascades after rain.

The Rhiwargor Waterfall walk is one of the best-known routes. It follows a valley into the hills towards a series of falls in a more remote part of the estate.

Wear walking shoes because paths can become muddy, rocky and slippery. Water levels also vary greatly after dry or wet weather.

Watch the Wildlife

The RSPB nature reserve around Lake Vyrnwy supports woodland, moorland, open water and farmland wildlife.

You may see pied flycatchers, redstarts and dippers during the warmer months, while buzzards, ravens and peregrine falcons can appear above the hills.

Bird hides around the lake give you somewhere to sit quietly and watch the water and shoreline. Bring binoculars because many birds remain some distance away.

Cycle Around the Lake

The road around the reservoir is popular with cyclists because it provides changing views without requiring complicated navigation.

The circuit is not completely flat, but it is manageable for reasonably confident riders who are comfortable sharing narrow roads with vehicles.

Families with younger children should choose quieter sections or suitable off-road routes rather than attempting the full road circuit.

Bring the Family

Lake Vyrnwy works well for families because you can make the visit as short or active as you like. A simple outing could include the dam, water tower, picnic and short woodland walk.

Older children may enjoy cycling, waterfall walks or searching for birds from the hides.

The site is mainly outdoors, so bring layers, waterproof clothing and something to keep younger children occupied if the weather closes in.

A Few Useful Tips

The nature reserve is free to enter, although parking charges apply at the main RSPB parking area. The wider visitor site is accessible throughout the year, but opening times for toilets and nearby food outlets vary.

The RSPB visitor centre is currently listed as temporarily closed. There is no RSPB café on site, but food and drinks are available nearby at the Artisans café, Lake Vyrnwy Hotel and in Llanwddyn village.

Most of the shorter surfaced trails are suitable for wheelchairs and pushchairs, although the more remote woodland and waterfall routes are rougher.

Dogs are welcome but must remain on leads because livestock and ground-nesting birds are present around the reserve.

There is no overnight parking. Llanwddyn has limited everyday facilities, so it is sensible to bring drinks and snacks or plan a café stop before starting a longer walk.

If heavy rain makes the trails uncomfortable, enjoy the dam and a short drive around the lake, then stop for food nearby rather than forcing a long outdoor walk.
