Cairngorms National Park is a national park in northeast Scotland, established in 2003. It was the second of two national parks established by the Scottish Parliament, after Loch Lomond and The Trossachs National Park, which was set up in 2002. The park covers the Cairngorms range of mountains, and surrounding hills. Already the largest national park in the United Kingdom, in 2010 it was expanded into Perth and Kinross.
