About Hart-Miller Island State Park

Hart-Miller Island State Park offers unique recreational opportunities accessible only by boat, providing a perfect escape with its sandy beaches and picturesque waters of the Chesapeake Bay.

Wilderness Landscape & Natural Heritage

Hart-Miller Island State Park is located in the Chesapeake Bay near the mouth of the Middle River in Maryland. Accessible solely by boat, this island park covers an area of over 1,100 acres, including both natural and reclaimed land. The southern portion of the island was created from dredged material and serves as a bird sanctuary, while the northern section is open for public recreation. The park’s shoreline and interior offer diverse habitats, supporting varied wildlife, especially avian species. Visitors can explore the sandy beaches, swim, and engage in beachcombing. The history of the island is tied to its reclamation efforts, which were completed in the late 20th century to beneficially reuse dredged spoil from the Baltimore Harbor and Channels. Recreation at Hart-Miller includes hiking along several miles of trails, bird watching, and picnicking, making it an attractive spot for nature enthusiasts and photographers. Its isolation and natural beauty provide an ideal setting for peaceful enjoyment away from bustling urban life.
