Stùc a' Chroin is most often climbed in conjunction with Ben Vorlich from Ardvorlich on Loch Earnside to the north. The normal routes of ascent is over the summit of Ben Vorlich and down its south west ridge to the Bealach an Dubh Choirein. From this bealach a rough path cuts very steeply up on the right (NW) side of the prominent buttress to the summit of Stùc a' Chroin. Returning from the bealach, Ben Vorlich can be skirted by a pathless traverse of grassy slopes to the pass on its east.
