The pointed peak of its west top (454 metres or 1,490 feet in elevation)[1] resembles a small mountain.

The summit area is largely treeless and comprises several rock outcrops and crags, its highest point being a rounded summit of 461 metres (1,512 feet) elevation,[1] unlike its lower west top.

The normal route is from the pay and display car park of "Ben An" (sic) by the shore of Loch Achray.

The path crosses the saddle heading northwest before picking up the course of another burn, the Allt na Cailliche, and following it steeply uphill below the crags of Ben A'an.

Close to the source of the burn the path swings westwards and behind the west top of the hill onto a col, from which it is a short climb to the summit of the west top which is the destination for most hikers.
