Eryri National Park

Natural wonders in Eryri National Park

Eryri National Park's landscape is defined by its glacial history, featuring Wales' largest natural lake, Llyn Tegid, and the high-altitude Llyn Llydaw on the flanks of Yr Wyddfa (Snowdon). The region's steep topography creates numerous cascades, including the 120-foot drop of Rhaeadr Fawr and the multi-tiered Swallow Falls. This collection highlights significant hydrological sites, from the industrial heritage of the Coedty Reservoir to the secluded falls of the Coed-y-Brenin forest and the Dolgoch ravine.
