Snowdonia National Park (Parc Cenedlaethol Eryri)

Wales' best-known slice of nature became the country's first national park in 1951. Every year more than 400,000 people walk, climb or take the train to the 1085m summit of Snowdon. Yet the park offers much more – its 823 sq miles embrace stunning coastline, forests, valleys, rivers, bird-filled estuaries and Wales' biggest natural lake.
