Stob Coire Easain is a fine summit situated on the western shores of Loch Treig. It is normally climbed in conjunction with its neighbouring Munro Stob a’Choire Mheadhoin to make a fantastic day on the hills. The summit lies at the southern edge of the rim of Coire Easain Beag which both hills surround. This corrie gives rise to some extremely craggy slopes on the NW summit ridge. Altogether Stob Coire Easain is made up of 3 ridges. The NE ridge runs round the bowl of the corrie connecting to a high col before eventually climbing to the summit of Stob a’Choire Mheadhoin. The NW ridge as mentioned skirts round the edge of the coire with dramatic slopes to the NE of the ridge. The SW ridge is not often used but sweeps down to the southern end of Loch Treig. The eastern slopes drop sharply to the Fjord like Loch Treig below and make a fine sight throughout the entire walk.
Stob Coire Easain is well seen form the Grey Corries ridge to the West, Stob Ban in particular. The steep corrie slopes are well appreciated from here.
The approach is usually from Fersit in the north with a long but enjoyable walk in along Stob a’Choire a Mheadhoin’s long northern ridge, summiting Stob a’Choire Mheadhoin before dropping to the col connecting to Stob Coire Easain. There are other routes from the south if coming in by train from Corrour Halt on the West Highland Line.
