Lake Vyrnwy & Rhiwagor Waterfall, Wales
Lake Vyrnwy came to be in the 1880s, after the city of Liverpool identified the valley as a suitable site for a reservoir to supply the city. The local population of Llanwddyn wasn't consulted and they subsequently found their entire village being flattened and rebuilt downstream. This doesn't sound ideal for them, although winter floods were apparently common. On the plus side, the location is now a beautiful one, with the lake itself, surrounding forests, waterfalls and rivers making a perfect setting for a day trip.
There are a number of trails marked out on the information boards on the small laybys around the reservoir, offering trails of various distances. We took the shorter one, the 'green route' which was a couple of miles in total, up to Rhiwagor Waterfall. We had our toddlers in tow, so this was sufficient!
There are plenty more photos I could add here, however that would be a bit of a spoiler. So why not head for a walk and pick one of the routes. Food and drink can be found at the Artisan cafe after crossing over the impressive dam.
Note also that Pistyll Raeadr is in the vicinity so you may fancy that too!
