ABERFOYLE, village and parish, Perthshire, Scotland, 341m. N. by W. of Glasgow by the L.N.E.R. Population of parish (1931) 1,014. The village is at the base of Craigmore (1,271 ft. high) and on the Laggan, a headwater of the Forth. In 1885 the duke of Montrose built a road over the east shoulder of Craigmore to the Trossachs but this does not take motor traffic. The Laggan drains the small lochs Ard and Chon, the first of which is the scene of incidents in Scott's Rob Roy. There are slate quarries on Craigmore.
