Scotland (Gaelic: Alba) is situated in the northern part of the island of Great Britain, and has a total area of about 78,770 square kilometres.  For further details, see the Wikipedia article at http://en.wikipedia.org/wiki/Scotland

Upland areas in the south and north dominate the landscape of the country.  Only in the central belt and north-eastern coastal plain, wherein lie the principle cities of Edinburgh, Glasgow and Aberdeen (and where most of the population reside) are there areas of lower lying land.  The geology of the country is very complex, giving rise to a diverse landscape of great interest and variety.  For more details on the geology of the country, see http://en.wikipedia.org/wiki/Scotland - Geology_and_geomorphology

The Scottish Highlands comprise the area to the north of the Lowland Central Belt, delineated geologically by the Highland Boundary Fault.  The mountains of the Highlands are of great variety, but mostly show a steep and craggy aspect. 

To the north and west are many islands, although only Harris, Lewis and South Uist in the Outer Hebrides, and Skye, Rhum and Mull in the Inner Hebrides, together with Jura and the Isle of Arran further south have summits on them over 500m in height.  The highest summit in the Scottish Islands is Sgurr Alastair (992m) on the Isle of Skye.

On the mainland, the Northern Highlands lie to the north of the Great Glen, a faultline running across the country from the south-west to the north-east through Loch Ness.  The highest summit in the Northern Highlands is Carn Eige (1183m).  To the south of the Great Glen lie the ranges of the Central, Eastern and Southern Highlands, the highest summits being Ben Nevis (1344m) (Scotland’s, and Britain’s, highest mountain), Ben Macdui (1309m) (in the Cairngorms) and Ben Lawers (1214m) respectively.

South of the Central Belt, and stretching to the English border, are the Southern Uplands.  These are mainly rounded grassy hills of lesser height than their northern neighbours.  The highest summits are Merrick (843m) in the Galloway Hills, to the west, and Broad Law (840m) in the Tweedsmuir Hills to the east.

A metric alternative to the Donalds and New Donalds, comprising all the hills in Southern Scotland of at least 500m in height and 100m of drop is offered below.  This list gives a wider choice of upland areas to visit than these older Southern Scottish lists.

Also below are new metric-only lists of hills in the Scottish Highlands, classified in 100 metre height bands.  These form modern alternatives to the Munros, Corbetts and Grahams - lists classified in the old measure of feet.  More lists will be added in due course.
