The Wells of the Rees are three springs, long since dried up, located within the ruins of Killgallioch Church. It is signposted off the New Luce to Bargrennan stage of the Southern Upland Way. If you park in the layby short of Balmurrie farm it is at least a 5 mile walk to the Well of the Rees. Of course there are Cairn na Gath, the Beehive Bothy and Laggangarn Stones to visit in between, so at 2.5 miles walked per site visited it is good value.
