Hart Miller Island

Hart Miller Island is a 1,663-acre river island located at the confluence of Back River and Middle River, which flow into Chesapeake Bay east of Baltimore. The island combines dunes with sandy beach, wetlands, and open water areas.

Maryland acquired the land in the late 1970s with the goal of transforming it into a public park. Dredged materials from Baltimore Harbor were used to expand and reshape the island.

The park serves as a crucial stopover for birds migrating along the Atlantic route. Visitors can observe numerous species here, particularly during seasons when large numbers of birds pass through.

The island is only accessible by private boat, so you will need to arrange your own transportation. There are no facilities or services on the island, so bring everything you might need.

The island sits only about 3 feet above sea level and features a 3,000-foot sandy beach. This very low elevation creates specialized habitat for particular wildlife and plant species.
