The Grampians make up the bulk of Scotland's highlands and contain the highest peaks and largest ranges, extending south and east of the Great Glen down to the Highland Boundary Fault, occupying almost half of the country's land area. Some of the area is relatively low lying, but not necessarily without topographical character. These regions include the Kintyre peninsula, Knapdale and Mid Argyll on the west coast, as well as eastern Aberdeenshire and Moray on the east. Rannoch Moor is a well-known area of low-lying land in an area surrounded by very high mountains and usually harks travellers' entrance into the highlands. The partly-forested Cowal peninsula has hills of intermediate height and considerable cragginess. The Grampians has the highest number of distinct mountain ranges in Scotland, particularly towards the west in Lochaber, where the mountains have much steeper sides than those found easterly. The highest eastern ranges can be split primarily into the Monadhliath, the Cairngorms and the Mounth. Many well-known mountains and hills are to be found here, such as Ben A'an, The Cobbler, Buachaille Etive Mòr, Bidean nam Bian, Schiehallion, Ben Macdui and Lochnagar. The highest mountain in this area is Ben Nevis, the highest mountain in Britain.
