Camano Island is a large island in Possession Sound, a section of Puget Sound. It is part of Island County, Washington, and is located between Whidbey Island and the mainland by the Saratoga Passage to the west and Port Susan and Davis Slough to the east. The island has one road connection to the mainland, via State Route 532 over the Camano Gateway Bridge at the northeast end of the island, connecting to the city of Stanwood.

Whidbey Island is the largest of the islands composing Island County, Washington, in the United States, and the largest island in Washington state. Whidbey is about 30 miles (48 km) north of Seattle, and lies between the Olympic Peninsula and the I-5 corridor of western Washington. The island forms the northern boundary of Puget Sound. It is home to Naval Air Station Whidbey Island. The state parks and natural forests are home to numerous old growth trees.
