Often called the Isle of Grapes. A bridge connects the island with the mainland. In 1878 Walter Echert began viticulture here. Years of experimentation and selection by Echert and others have produced a variety of grape, the Island Belle, suited to the soil and the climate. By the 1940s, three wineries and two juice plants operate on the island.

There are still vineyards and wineries on the island but other wine-growing regions in the state have eclipsed them in terms of production. However, Stretch Island remains historically significant in the formation of wine culture in Washington. Stretch Point State Park is located at the northern tip of the island.

The island’s namesake, Samuel Stretch was a gunner’s mate on the U.S. Exploring Expedition of 1841.
