The Isle of Arran or simply Arran is an island off the west coast of Scotland. It is the largest island in the Firth of Clyde and the seventh largest Scottish island, at 432 square kilometres (167 sq mi). Historically part of Buteshire, it is in the unitary council area of North Ayrshire. In the 2011 census it had a resident population of 4,629. Though culturally and physically similar to the Hebrides, it is separated from them by the Kintyre peninsula. Often referred to as "Scotland in Miniature", the island is divided into highland and lowland areas by the Highland Boundary Fault and has been described as a "geologist's paradise".

At only one point does it venture inland, and this is to climb the 600-foot (180-metre) pass at Boguillie between Creag Ghlas Laggan and Caisteal Abhail.

The route is fully waymarked, using marker posts featuring a gannet.
