Goose Island is a 710 acre park located on an island in the Mississippi River about 3 miles downstream of La Crosse, Wisconsin. Access is from County Road GI on the Wisconsin side of the river. The park is operated by the La Crosse County Parks Dept., and it features over 400 camp sites and a large calendar of planned activities.

The Root River flows into the Mississippi River just above the north end of Goose Island. As a result, the river here is very wide and has extensive silt islands that form a maze of back channels and sloughs.
