On the walk you will enjoy stunning views of Llyn Cwellyn and the surrounding mountains.The walk starts from the village of Rhyd Ddu and follows woodland trails through Beddgelert Forest before climbing above Llyn Cwellyn to Foel Rudd and then on to the Mynydd Mawr summit. There are interesting geological formations, rocky outcrops and breathtakingly beautiful views to enjoy. It's also a fairly quiet walk with most people heading to Snowdon from Rhyd Ddu.
If you'd like to continue your climbing in the area then the Snowdon Rhyd Ddu Path starts from the village too. You could also head along the wonderful Nantlle Ridge.

Further Information and Other Local Ideas

Just to the west you can explore the Dorothea Quarry where you'll find the remains of the old mining houses and a series of scenic lakes including Llyn Nantlle Uchaf. The quarry is one of the significant sites on the Snowdonia Slate Trail which runs through the area. The circular long distance trail can be used to visit several of the other historic mining areas located in the World Heritage Site. Heading north along the trail would take you to Dinorwic Quarry which was at one time the second largest slate quarry in the world. The quarry is located on the edge of Padarn Country Park where there are some lovely waterside trails along Llyn Padarn and Llyn Peris.
The Lon Gwyrfai multi user path skirts the eastern edge of the forest. The trail runs betweenRhyd Ddu and Beddgelert along a nice easy surfaced path.
