Door Peninsula

The Door Peninsula is a peninsula in eastern Wisconsin, separating the southern part of the Green Bay from Lake Michigan. The peninsula begins in northern Brown and Kewaunee counties and proceeds northeast to include all of Door County. It is the western portion of the Niagara Escarpment. Well known for its cherry and apple orchards, the Door Peninsula is a popular tourism destination. With the 1882 completion of the Sturgeon Bay Ship Canal, the northern half of the peninsula became an island.
