The Corbetts are mountains in Scotland between 2,500 and 3,000 feet in height with a drop of 500 feet all round. They are named after John Rooke Corbett who compiled the original list. The complete list of Corbetts can be found in the Munro Tables published by the Scottish Mountaineering Club. (www.smc.org.uk)
This list indicates that there are 220 Corbetts. However two of these mountains, located between Glen Shiel and Loch Quoich, are given the same height and the drop between them is less than the stipulated 500 feet. This means in fact that there are only 219 Corbetts.
Corbett Tops have the same height criteria as Corbetts but only have a drop of at least 30 metres all round. They include all the Corbetts and therefore there are around 670 Corbetts and Corbett Tops.
A person climbing the Corbetts is called at Corbett Bagger while someone who has climbed all the Corbetts is called a Corbetteer.
