The Isle of Arran (Scots Gaelic: Eilean Arainn) is the largest island in the Firth of Clyde, Scotland, with an area of 167 square miles (433 km2). It is in the unitary council area of North Ayrshire. In the 2001 census it had a resident population of 5,058.
The island lies in the Firth of Clyde between Ayr and Kintyre. The profile of the north Arran hills as seen from the Ayrshire coast is a well-known sight referred to as the "Sleeping Warrior" due to its resemblance to a resting human figure. The highest of these hills is Goat Fell at 874m (2,866 ft). There are three other Corbetts all in the north east; Caisteal Abhail, Cìr Mhòr and Beinn Tarsuinn. Bheinn Bharrain is the highest peak in the north west at 721 metres (2,370 ft).
The largest valley on the island is Glen Iorsa to the west, whilst narrow Glen Sannox (Gaelic: Gleann Shannaig) and Glen Rosa (Gaelic: Gleann Ròsa) surround Goat Fell, which is to the east of these Glens. The terrain to the south is less mountaineous, although a considerable portion of the interior lies above 350 metres (1,100 ft) and the summit of A' Chruach reaches 512 metres (1,680 ft). There are two other Marilyns in the south, Tighvein and Beinn Bhreac.
The island is sometimes referred to as "Scotland in Miniature"
