SNOWDONIA

Snowdonia (eryri) 
National Park

Snowdonia National Park covers more than 800 square miles across the mountains and valleys of North Wales and was established in 1951 as one of the first national parks in the UK. At its heart is Yr Wyddfa, the highest mountain in England and Wales, a peak that has drawn walkers, climbers and poets for centuries. The landscape is shaped by glacial valleys, ancient woodlands, rugged ridges and over a hundred lakes. It is also a place steeped in Welsh culture and legend, from tales of King Arthur to the enduring traditions of local communities. Today visitors can follow mountain paths to dramatic summits, explore quiet valleys dotted with castles and slate mines, or simply enjoy the wild beauty that makes Snowdonia a true landmark of the British outdoors.

our mission

This website was created during the second coronavirus lockdown, a time when the nation's collective mental health was at an all-time low. Hiking can provide a psychological reset, a way of forgetting the daily challenges we face and connecting with the healing powers of Mother Nature. Our mission at The Lost Peak is to make people happy by providing an easy-to-use and informative resource for exploring the Great British outdoors.
