Description by the author

Experience the unique slate landscape of North Wales` latest World Heritage Site and enjoy the wonders of the Eryri National Park (Snowdonia).

This trail visits some of the less-frequented but beautiful parts of Snowdonia/Eryri, passing through all the major mountain ranges, offering a range of experiences from mountain to forest, lake to river, from the valley to the sea. All along the trail are fascinating things to be seen and experienced. From small sleepy villages to the honeypots of Llanberis and Betws y Coed, this trail provides a wealth of variety.

This trail is also a joy for narrow gauge railway enthusiasts, as it visits the Penrhyn Quarry Railway, Llanberis Lake Railway, Snowdon Mountain Railway, the Welsh Highland Railway and the Ffestiniog Railway.
