D'Arcy Island is located in the
Haro Strait, whose waters run between southern
Vancouver Island and, roughly,
San Juan Island. Little D'Arcy Island is tucked up near the eastern side of its larger partner, and
today, the area is part of a provincial marine park, established in 1961.
1 D'Arcy Island was a lazaretto from 1891 to 1924 mostly for Chinese sufferers of Hansen's
Disease; the Sencot'en name for the island is Ctesu.
