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.

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.
