Felled Then Sculpted into a hand in legacy of the once was the tallest tree in the UK! Stood at then 147m in all her glory unfortunately from a storm in 2010. Where March 2011 they had stumped it to 50m then autumn 2011 the awesome absolutely incredible sculpture of a hand represents storm had damaged the actual douglas fur that bad that it had to be felled at 50m for safety of numerous accounts in that area as the devastation if left to fall on its own I imagine that it would have and could have been catastrophic and unbelievable to even think on, as it would no doubt have touched the lake itself if was left and In process ripping down many of the surrounding small giants that grew in that part of the forest. I would have loved to have seen what the actual tree looked like in all her prime of height but ive not managed to find anything yet my search continues 2years on. I felt a huge hit of the most hardcore feeling of emotion. I felt a sense of link and connection with the whole ethos in the giants and the trail that’s left still today, I’ve never looked at a single tree in the same ever since. Please everyone take extra care whilst you’re here as there’s been issues recently with vandalism and even cutting the surrounding areas illegally that is a protected area and it’s not a place that usually has fallen into a victim of crimes but it is and it has rubbish is to be taken home

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.
