The hills of the great Dyfnant Forest were once rode by Welsh hero Owain Glyndŵr, who led the rebellion against English rule in Wales during the 15th century. Today, the woodland is still enjoyed by those on horseback, as well as hikers on the Glyndŵr’s Way long-distance trail. The coniferous woodland here is part of the National Forest for Wales project.

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.

Perfect gravel riding on the descent 😊 - after, let's face it, the long grind up to the memorial!

The track from the East is broken but doable on a gravel bike - I had to push the last few hundred metres. Awkward terrain - large stones - and plenty of puddles - but a fabulous day on 2 wheels!

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.

The Straining Tower at Lake Vyrnwy is an intake tower built to extract water from the lake. The tower stands on the north shore of Lake Vyrnwy, near the village of Llanwddyn, in Powys, Wales. The Lake Vyrnwy dam project was designed to provide a water supply to the city of Liverpool and work on the dam began in 1881. On its completion 11 years later, the lake was the largest reservoir in Europe and water was drawn from it into the straining tower and carried to Liverpool on a 110km-long aqueduct. The engineers for the project were Thomas Hawksley and George Frederick Deacon, although the straining tower was entirely Deacon's design. The tower is constructed in a Gothic Revival style, purportedly based on the tower of the castle at Chillon, Switzerland. It draws heavily on the contemporaneous work of William Burges, whose Cardiff Castle and Castell Coch are clear influences. The straining tower is a Grade I listed building
