Bwlch Drws Ardudwy

The longer of two walks in the area, this circular route (a moderate graded walk) will lead you towards Bwlch Drws Ardudwy, which is the gap between Rhinog Fawr and Rhinog Fach. This walk gives you the opportunity to experience the rugged Rhinogydd National Nature Reserve, before leading you back to the Graigddu woodland. Many say that the Rhinogydd is one of the last true wilderness in Wales, and once you’re there it’s easy to see why.

A word of warning - since this is a National Nature Reserve which is famous for its wildlife and wilderness, there are no markers on the path, and the path can get very wet. You will need to carry a map and wear strong, waterproof shoes if you’re going to follow this route.
