A815 road

The A815 is a major road in Argyll and Bute, Scotland. It runs for about 35.7 miles (57.5 km) from the A83, near Cairndow, in the north, through Dunoon, to Toward in the south. For a short distance, from Sandbank and through Dunoon, the A815 is paralleled by the A885, which takes a more inland route compared to the A815.

The A815 passes beside two sea lochs, Loch Fyne and the Holy Loch, and one substantial freshwater loch, Loch Eck, whilst its final stretch is along the Firth of Clyde.
