Snowdonia

Snowdonia is a region in northwest Wales concentrated around the mountains and glacial landforms of massive Snowdonia National Park. The park's historic Snowdon Mountain Railway climbs to the summit of Wales's highest mountain, Mount Snowdon, offering views across the sea to Ireland. The park is also home to an extensive network of trails, over 100 lakes and craggy peaks like Cader Idris and Tryfan. ― Google
