Packed with great mountain climbs, idyllic river walks, lakeside rambles and coastal hikes, Snowdonia National Park is the perfect getaway location for hiking – our pick of the best walks in Snowdonia, Wales.

Lake and mountains in spring and summer

Snowdonia National Park covers 823 square miles of north-west Wales and contains the country’s highest peak, Snowdon.


The region, designated as a national park in 1951, was sculpted by glaciers, leaving behind a spectacular landscape of craggy mountains and hills, deep valleys and over 100 lakes.

There are numerous ways to explore the park – mountain biking routes, driving tours and even by canoe – but for a truly immersive experience, why not take on one of Snowdonia’s best walks?

From a classic Snowdon ascent to a less-gruelling riverside amble along the Afon Artro, here is our guide to the best walks in Snowdonia. Each route includes walking directions and a map.
