The Clisham (An Cliseam) at 799 metres is the highest mountain in the Outer Hebrides and the archipelago’s only Corbett. It has superb views across to the other islands of the chain and the sea.

The direct ascent (5 km, 640 metres of ascent) starts from the car park on the A859 road, between Tarbert and Ardvourlie where the Abhainn Mharaig flows from the mountain (GR NB 173 056) and climbs the southern-eastern flank. The approach is initially boggy and free range and then ascends steeply on a path that meanders through the rocks.

From the car park take the path on the south side of the river which starts off a bit boggy. After a short distance the path fades and you need to continue directly uphill, ascending the mainly grassy slopes. Once higher up on the ridge the path between the boulders becomes more obvious and leads to the summit trig and shelter cairn for great views of the other peaks of the Clisham horseshoe and the coast of Harris.
