The Grampian Mountains are a Scottish mountain range stretching nortseast - southwest from Aberdeen to the west coast, including Lochaber, Cairngorms, Glen Coe, Ben Nevis. In fact, this is almost half of Scotland. Bordering south are the Scottish Central Lowlands. The Northern boundary is clearly defined by the Great Glen, Fort William to Inverness.
The other two main mountain ranges in Scotland are the Southern Uplands, and the Northwest Highlands.
