There are three National Parks in Wales covering an area of 4122 sq km (1591 sq miles). This represents approximately 20% of the land area of Wales. Snowdonia was designated in 1951 followed by Pembrokeshire Coast in 1952 and Brecon Beacons in 1957.

National Parks were created to protect the most beautiful and imposing landscapes in the UK. The statutory designation recognises the national importance of such landscapes and gives them a high degree of protection.

Snowdonia is a mountainous region in northwestern Wales and a national park of 823 square miles (2,130 km2) in area. It was the first to be designated of the three national parks in Wales, in 1951.
