1911 Encyclopædia Britannica/Aberfoyle
Aberfoyle, a village and parish of Perthshire, Scotland, 34¼ m. N. by W. of Glasgow by the North British railway. Pop. of parish (1901) 1052. The village is situated at the base of Craigmore (1271 ft. high) and on the Laggan, a head-water of the Forth. Since 1885, when the duke of Montrose constructed a road over the eastern shoulder of Craigmore to join the older road at the entrance of the Trossachs pass, Aberfoyle has become the alternative route to the Trossachs and Loch Katrine. Loch Ard, about 2 m. W. of Aberfoyle, lies 105 ft. above the sea. It is 3 m. long (including the narrows at the east end) and 1 m. broad. Towards the west end is Eilean Gorm (the green isle), and near the north-western shore are the falls of Ledard. Two m. N.W. is Loch Chon, 290 ft. above the sea, 1¾ m. long, and about ½ m. broad. It drains by the Avon Dhu to Loch Ard, which is drained in turn by the Laggan. The slate quarries on Craigmore are the only industry in Aberfoyle.
