MARK Y Garn Horseshoe
The Y Garn Horseshoe is one of Snowdonia's best structured mountain loops — a clean, elegant circuit that climbs Y Garn via its broad east ridge, crosses the high ground above Cwm Idwal, and returns through the dramatic Devil's Kitchen. It's big, scenic, and atmospheric without ever becoming technical, making it the perfect 'serious but accessible' mountain day. Huge views across the Glyderau, Nant Ffrancon, and the Snowdon massif throughout.

The Route
🏔️ Route Character
The Y Garn Horseshoe is clean, scenic, and perfectly balanced. It gives you big mountain terrain without the exposure or technicality of Tryfan or Bristly Ridge. The character shifts throughout: East Ridge — steep, spicy, and panoramic; Y Garn Summit — huge views in all directions; Ridge to Llyn y Cwn — rugged, rocky, atmospheric; Devil's Kitchen Descent — steep, dramatic, iconic; Llyn Idwal Return — easy, scenic finish.
It's one of the most repeatable mountain loops in Snowdonia — big enough to feel serious, friendly enough to stay enjoyable.
