Llanwddyn is a small village beneath the Llanwddyn Dam on Lake Vyrnwy. The original village was flooded when the reservoir was created in the 1880s. There are a couple of accommodation options in the surroundings: the beautifully situated Lake Vyrnwy Hotel and Spa to the north-east and the Lake Vyrnwy campsite to the east.

Gorgeous area. Be aware the road/trail on the south side (including access to/from Llanymawddwy) are currently closed due to damage from storm Darragh. See https://www.hdcymru.co.uk/our-visitor-sites/lake-vyrnwy/storm-darragh/ for more details.

There is a little cafe above the main car park for a coffee and cake after the "gift shop" labelled walks. As usual, Komoot makes the walk easier than using signposts - remember to download to the phone app. Kayaking/canoeing around the lake is only possible for about half of it due to a protected bird sanctuary.

Amazing dam - there are some plaque's at the end of it to note some of the key dates. Impressive structure. I visited out of season and it was really tranquil.

Situated at the north-end of the lake, this hide overlooks a wonderful lagoon and if you’re lucky, you might glimpse an otter or two playing in the pool.

Lake Vyrnwy is a reservoir in Powys, Wales, built in the 1880s for Liverpool Corporation Waterworks to supply Liverpool with fresh water. WHICH THEY DID NOT NEED AGAIN!!! It flooded the head of the Vyrnwy valley and sadly submerged the whole village of Llanwddyn.

Get your picnic out - what an amazing location within the sculpture park. Several benches here or just bring a blanket and sit on the grass. The dam makes an amazing backdrop to this location !!

A great place to cycle, with well paved and flat roads all the way around. It can be hard to see much of the lake for the trees on the North side but there are some better view points to stop at on the South.
