The UK has 15 national parks to its name – 10 in England, three in Wales and two in Scotland – but they vary greatly in size, with some only covering a few hundred square kilometres while others span many thousands.
Biggest national parks in UK
Cairngorms National Park, Scotland

Scotland’s Cairngorms are the biggest national park in the UK at 4,528km2. The Cairngorms mountain range sits at the heart of the national park, with lochs and lochans punctuating the rest of its landscapes. Winter in the Cairngorms is particularly magical, with golden eagles, snow buntings, ptarmigans, mountain hares and reindeer visible in the starkly white landscapes.

Lake District National Park, England

The Lake District National Park encompasses all the central Lake District, famed for its landscapes, lakes and mountains. As the second national park to be established in the UK – after the Peak District, which was designated a month earlier in April 1951 – the Lake District National Park covers an area of 2,362km2, making it the largest national park in England and Wales.

Yorkshire Dales National Park, England

Covering most of the Yorkshire Dales, the Howgill Fells and Orton Fells, the Yorkshire Dales National Park has the highest proportion of privately owned land, with over 95 per cent of its area in private hands – mostly belonging to farmers and locals.
Along with Exmoor, Bannau Brycheiniog (Brecon Beacons) and Northumberland National Parks, the Yorkshire Dales National Park holds International Dark Sky status, thanks to its low levels of light pollution and good conditions for astronomy. Limestone scenery is a key feature of the Yorkshire Dales, with dry-stone walls lining the countryside.

Eryri (Snowdonia) National Park, Wales

While the Cairngorms are considered to be the most mountainous national park in the UK thanks to its extensive ranges, Eryri (Snowdonia) has the highest concentration of mountains over 3,000 feet – this height defines a mountain as a Munro in Scotland. The region takes its name from Wales’s highest mountain, Yr Wyddfa (Snowdon), which sits within the national park. Eryri was the first of three national parks to be designated in October 1951, and today spans 2,142km2.
Loch Lomond and the Trossachs National Park, Scotland

Along with the Cairngorms National Park, Loch Lomond and The Trossachs National Park was established by the Scottish Parliament in 2002, extending to much of the western part of the southern Scottish Highlands from the base of Loch Lomond (one of the biggest lakes in the UK), just north of Glasgow. With an area of 1,865 km2, it includes 21 Munros, including Ben Lomond and Ben Lui. The area is popular with visitors, thanks to its proximity to Glasgow and other major Scottish cities.
