Glen Rosa is a valley on the Isle of Arran in the Firth of Clyde, western Scotland. It can be reached from the road just outside Brodick, the primary town on Arran. The trek up the glen is fairly flat, gaining less than 200m in altitude. The valley is near Goat Fell.
There is a campsite at the foot of the glen.[1]
Glen Rosa is convenient to reach some of the main peaks on Arran.[2]
