River Add

The River Add near Kilmichael Glassary

The River Add (Scottish Gaelic: Abhainn Àd) is a river which runs through Argyll and Bute on the West of Scotland. Historically, it was known as the river Airigh but to avoid confusion with the Aray (which gives its name to Inveraray), it was renamed the River Add.

The surrounding valley still retains the name Glen Airigh, and The river gave rise to the name Glassary (Glas Airigh), by which the surrounding district of Glassary is known. In turn, this forms the second part of the name of Kilmichael Glassary, a village in the lower parts of the valley. Kilmichael Glassary is the home village of the founder of the Campbells of Auchinbreck, a senior cadet branch of Clan Campbell. The 1,500 feet (460 m) high Marylyn of Beinn Dubh Airigh is situated on the northern edge Glen Airigh, separating it from Glen Awe.
