The Munros
Scotland's highest mountains are known as Munros, named after Sir Hugh T. Munro who in 1891 surveyed all the country's mountains above 3000 feet (914.4 metres) and produced his Tables which catalogued 236 peaks that he deemed to be individual mountains. Over the years and with advances in surveying methods, there have been several revisions to Munro's original listing, the latest being in 1997. Currently, there are 284 Munros and a further 511 'Tops' (those peaks above 3000 feet which are part of a range or ridge but which are judged not to be a separate mountain). Climbing all the Munros, or Munro-bagging as it's usually called, is a very popular pursuit amongst the climbing and hillwalking fraternity. The first recorded Munro-bagger to climb all the 3000-feet peaks was the Rev. A. E. Robertson in 1901 and since then, the Scottish Mountaineering Club has recorded over 2800 intrepid souls who have 'compleated'.

The Top Ten Munros are:

1. Ben Nevis
2. Ben Macdui
3. Braeriach
4. Cairn Toul
5. Sgor an Lochain Uaine
6. Cairngorm 
7. Aonach Beag
8. Aonach Mor
9. Carn Mor Dearg
10. Ben Lawers  (3983 ft/ 1214 m; Ben Lawers range)

The Corbetts
The Corbetts is the collective name given to the 221 distinct mountains in Scotland which are between 2500 (762 m) feet and 2999 (914 m) feet, and which have a re-ascent of 500 feet on all sides. They are named after John Rooke Corbett who in 1930 became the first person to climb all the 2000-feet-high peaks in Scotland. (He was also only the second person ever to complete all the Munros and Tops and the fourth to complete only the Munros). Like Munro-bagging, Corbett-bagging is a very popular pursuit. It has its own dedicated followers who claim that, in general, the Corbetts provide a better day's walking than the higher peaks.

The Top Ten Corbetts are:

1. Beinn Dearg
2. Foinaven  (
3. Sgurr 'Choire-bheithe
