Camano Island is a large island in the Possession Sound portion of Puget Sound, located in Island County, Washington, between Whidbey Island and the mainland. The body of water separating Whidbey Island and Camano Island is called Saratoga Passage. Camano Island is separated from mainland Snohomish County by Davis Slough near the city of Stanwood. The island is reached via State Route 532 over the Mark Clark Bridge in the northeast of the island.
There were 13,358 residents on the island as of the 2000 census, but the population peaks at 17,000 during the summer months with retired "snowbirds." The island has a total land area of 102.99 km² (39.77 sq mi), though it was larger before the Great Slide of 1825. Kristoferson Lake is the largest lake on Camano Island.
