A walk to the foothills of the Rhinog mountain range

Bwlch Drws Ardudwy is the longer of two walks in this area. Graigddu is the shorter alternative. This circular route will lead you through Graigddu woods towards Bwlch Drws Ardudwy—the gap between Rhinog Fawr and Rhinog Fach.

The route is the perfect opportunity to experience the ruggedness of the Rhinogydd mountain range.

Why this path?

It is often said that the Rhinogydd mountain range is one of the last true wilderness in Wales. This rocky, heather-clad area towards the south of the National Park is a designated National Nature Reserve and is home to an abundance of important and rare species.

As a moderate path, it can be suitable for those who are eager to begin their journey to lesser-known parts of the National Park or for an adventurous family outing.

Rhinog National Nature Reserve

The Bwlch Drws Ardudwy path will take you into the Rhinog National Nature Reserve—an area home to many important habitats and species.

The heathland, which covers nearly 70% of the reserve, is punctuated by the craggy outcrops of the Rhinogydd mountains, including Rhinog Fawr, Rhinog Fach, Y Llethr and Moel Ysgyfarnod to name only a handful.

Wooded areas of the reserve exhibit a mixture of trees and provide habitats for various mosses, liverworts, fungi, insects, birds, and bats.

Many of Eryri’s smaller lakes call the Rhinog reserve their home, including Llyn Du and Llyn Cwmhosan.
