Government Island State Recreation Area encompasses three islands in the Columbia River north of Portland, and accessible only by boat. The largest and most developed is 1,760-acre Government Island. The area also includes Lemon and McGuire Islands.

The main island has 15 miles of shoreline with two docks and a floating tie-up on the north side. Camping is permitted below the vegetation line around the perimeter; there are no designated campsites. Pit toilets and picnic tables with barbecue grills are located throughout the perimeter.

The interior of the island contains protected natural areas, such as Jewett Lake, and is accessible only by permit through the Port of Portland. The islands feature freshwater wetlands that support a variety of wildlife species, including several species of salmon, salamanders, bats, turtles, and birds.
