Craigroyston or Rob Roy's Cave, a cavern in Buchanan parish, Stirlingshire, at the E side of Loch Lomond, 7 furlongs N by W of Inversnaid. It occurs, within a steep rugged rock, a little above the water's edge; is wild and deep; and has a narrow entrance, partly concealed by fallen blocks. Robert Bruce spent a night in it after the battle of Dairy; and Rob Roy frequented it as a place of consultation with his subalterns for planning his raids.
