An Coileachan is the most southern Munro in the Fannaich range and rises directly from the northern shores of Loch Fannaich. The summit has a series of ridges branching off of it but the main ridges run NW and SE. The NW ridge leads to a high col called Bealach Ban before joining up with the summit ridge of connecting Munro Meall Gorm. The SE ridge drops to the shores at the head of Loch Fannaich. This is the usual route of ascent and/or descent. Both of these ridges have crags on their eastern faces. The most impressive views from An Coileachan are that of Loch Fannaich.
An Coileachan is usually climbed from the south from the dam at the head of Loch Fannaich. Combining this Munro with Meall Gorm or perhaps the Fannaichs even further north or west should provide a fantastic day on the hills in this superb area of the Scottish Highlands.
