On the slopes above the east shore of Loch Lomond where a spring issues from the ground, a horseshoe-shaped low construction of stone in a boggy field marks St. Maha's Well. The same Maha for which the nearby village of Balmaha is named. According to people would use water from this well as a curative.

Just a few metres away on a low rise is a small standing stone and the remains of a small stone enclosure. Possibly another well head, now turfed over. The standing stone may well be the remains of a mediaeval stone cross marking the holy well.
