About waterfalls in North Wales

North Wales's topography — high rainfall, steep valleys and hard metamorphic rock — creates some of the most impressive waterfalls in Britain. Snowdonia receives over 3,000 mm of rain annually at the summit and the rivers that drain the mountains carve dramatic gorges and falls before reaching the coastal plain.

Pistyll Rhaeadr stands apart. Located in the Berwyn Mountains south-east of Snowdonia — one of the least-visited hill ranges in Wales — it drops 80 metres through a natural arch cut through solid rock by the Afon Disgynfa. It was described by the 17th-century traveller George Borrow as "the most beautiful thing he had seen in Wales." It remains private land but is accessible year-round via a teahouse and small car park at Llanrhaeadr ym Mochnant.

Swallow Falls on the Afon Llugwy near Betws-y-Coed is the most visited, easily reached from the A5. Aber Falls near Abergwyngregyn — a 40-minute walk through an NNR — is one of the most dramatic in North Wales, set in a glacially carved cwm. Dolgoch Falls near Tywyn can be combined with a trip on the Talyllyn Railway, with a halt at Dolgoch station.
