Glas Bheinn Mhor sits at the eastern end of a three way set of ridges that connect Glas Bheinn Mhor, Ben Starav and Beinn nan Aighenan. Although Glas Bheinn Mhor is smaller than its surrounding neighbours it has a lot of character and should make for a good climb. Its north western summit ridge is a formidable sight when viewed from Glen Etive and makes an excellent route for ascent / descent. As mentioned Glas Bheinn Mhor is normally climbed in a group of three but it can be climbed singularly either from the single track road that runs through Glen Etive or from further east towards Loch Tulla involving a fairly long walk in. Parking is available at both starting places.
From the summit there are fantastic views east towards the next set of hills in the Glen Etive region, the fantastic Stob Coire an Albannaich and Meall nan Eun as well as being a superb vantage point to look back and view the complex summit ridges of Ben Starav.
