A wonderful walk taking in a variety of interesting landscape features, including Rhaeadr-y-Cwm, one of the most impressive waterfalls in Snowdonia.
The walk starts from Llyn Dubach, which sits underneath Carreg y Foel Gron. If you look up to the crag you may see some rock climbers. Some boggy ground has to be crossed to get to Llyn Morwynion. This delightful lake is steeped in legend – it is thought to be where Blodeudd and her maidens of Ardudwy were chased by the wizard Gwydion. The maidens drowned and Blodeudd was turned into a bird – at least that is what happened according to the Mabinogion!
The route then continues down into the bottom of Cwm Cynfal and follows Afon Cynfal back up the valley. Soon enough you will have superb views of Rhaeadr-y-Cwm. This waterfall drops down a steep ravine in a series of steps, losing over 100m in height overall. The biggest cascade is more than 40m high – catch it after heavy rain and it will be raging with white water.
There is plenty of parking space at Llyn Dubach. There is also a car park (and viewpoint) by the side of the B4391 and close to the path coming down from Llyn Morwynion.
Mostly good tracks and footpaths, but some very boggy sections, particularly during rainy periods.
