Scotland's Landscape
Scotland's mainland is broadly divided into three regions: the Highlands: a rugged mountainous terrain covering the north and north-west: the Central Lowlands (also called the Midland Valley), a flatter plain between the Highland Boundary Fault and the Southern Upland Fault that contains the majority of Scotland's population, and the Southern Uplands, a hilly region bordering England.
Scotland's only land border is with England, running 154 km from the Solway Firth in the west to the River Tweed on the east coast.
Scotland has two National Parks: Loch Lomond & The Trossachs (established 2002, covering 1,865 km²) and Cairngorms National Park (established 2003, the largest in the UK at 4,528 km²).
