Creag Ghlas Laggan

Creag Ghlas Laggan stands on the Isle of Arran in south-western Scotland. It is the highest point of a seven-mile ridge that runs between the A841 road and the Sound of Bute. The hill is classed as a Marilyn, meaning it has a topographic prominence of at least 150 metres. Two main paths lead to the summit. One follows a well-trodden route from Lochranza to Bearradh Tom a' Muidhe. The other starts from the parking area at Boguillie. The hill’s geology is unusually varied. On its north-western slopes lies Hutton’s Unconformity in Dalradian metasediments. The north-east shore shows Carboniferous limestone and Permian desert deposits. At the south-eastern end are Devonian Old Red Sandstone layers. From the summit, views stretch towards Caisteal Abhail and other peaks such as Goat Fell. The ridge itself offers open moorland and gentle slopes. The path from Lochranza winds through heather and grassland before climbing steadily. The shorter route from Boguillie is steeper but quicker. Both lead to the same summit where the landscape opens up in all directions.
