It is a tidal island, linked to the mainland by a natural shingle causeway called the Doìrlinn near Campbeltown at low tide.
Dr Gillies in his "Place Names of Argyll" appears to accept the popular derivation, Double-pointed (Da-Bharr) Island.
The lighthouse was automated in 1983, and today, Davaar is inhabited by the caretakers of the Island who run the holiday cottages and oversee the farming activities including Rare breed sheep, and Highland Cattle.
While the men and women of the ROC watched for enemy activity around the loch, the anti-submarine net (positioned between Davaar and Trench Point) was maintained by the wrens, officers, and ratings stationed in the Boom Defence Depot on the opposite shore.
Davaar's observation post has been restored and tastefully converted into a unique place to stay.
