The Doon is mentioned in Burns' classic narrative poem "Tam o' Shanter", along with the Brig o' Doon, which spans 72 feet (22 metres) across the river, just outside Alloway. The river is also the major setting for his lesser-known poem "The Banks O' Doon".
Course
The River Doon begins at Loch Doon, flowing in a northwesterly direction from the loch. The loch is dammed at the source of the river by the Loch Doon Dam. The river flows north from the loch through Ness Glen, a densely forested gorge.[2]
The Doon ends its nearly 40-mile course at the Firth of Clyde, just south of Ayr.[3]
