Yes, Glas Bheinn Mhòr is frequently ascended as part of a more extensive multi-Munro traverse within the Ben Starav range. Experienced hillwalkers often combine it with peaks like Ben Starav and Beinn nan Aighenan, making for a demanding but highly rewarding day out. Some ambitious routes can cover up to five Munros, starting and finishing in Glen Etive, requiring a long summer's day.
While specific routes vary, a challenging ascent of Glas Bheinn Mhòr alone, or as part of a multi-Munro day, can involve significant elevation gain. For instance, a route bagging five Munros in the area can entail nearly 2,000 meters (6,560 feet) of ascent over approximately 28 kilometers (17.4 miles).

A unique feature is standing with one foot in two different Scottish council areas (Argyll and Bute and Highland) at the summit.
