Glas Bheinn Mhòr

Glas Bheinn Mhòr, at 997 metres, is the second Munro of the Ben Starav group above Glen Etive, almost always climbed as an extension of Ben Starav along a fine, airy ridge.

From Ben Starav's summit, the route heads south-east along the top of crags, with care needed in poor visibility given steep drops to the left, continuing across the north flank of Stob Coire Dheirg. The path descends towards Glas Bheinn Mhòr, reaching a bealach before a further ascent — often via the minor top of Meall nan Trì Tighearnan — to the airy summit of Glas Bheinn Mhòr itself, with commanding views back across the surrounding lochs and glens.

The descent follows the grassy east ridge, curving left before dropping to a lower bealach at 738 metres. From here the route turns down the glen, keeping to the right of the stream on a path that becomes increasingly boggy in places, eventually rejoining the outward hydro track back towards Coiletir and the start.

The round trip taking in both Ben Starav and Glas Bheinn Mhòr from the Glen Etive roadside is around 18-20 kilometres with substantial ascent, typically eight to ten hours for the full traverse.

Very fit and experienced parties sometimes extend the day further to include the outlying Munro of Beinn nan Aighenan, or continue east to Stob Coire an Albannaich and Meall nan Eun, though attempting all five Munros of this group in one outing is a serious undertaking reserved for exceptionally strong walkers.

Parking near Coiletir is free but very limited, holding only a handful of vehicles; there is no public transport to the start.
