Hart-Miller Island State Park

Hart-Miller Island is a 1,100-acre island located in View of Hart-Miller Island State Park BeachBaltimore County on the Chesapeake Bay near the mouth of Middle River. It is accessible only by personal boat. The western shore of the island offers safe mooring, wading and access to a 3,000-foot sandy beach. Hart-Miller Island State Park also includes Hawk Cove and Pleasure Island, which also provide recreational opportunities and camping.

On May 7, 2016, the south cell of Hart-Miller Island officially opened for public access for the first time since construction began on the dike in 1981. The south cell will be open and staffed Thursdays through Mondays from 8 a.m. to 6 p.m. The south cell contains over eight miles of trails that circle around a large, beautiful pond and include breathtaking views of the Chesapeake Bay. The south cell may be closed due to inclimate weather. Follow the Gunpowder Falls Twitter account for closure messages due to weather. The 1.8 mile Long Trail Loop boasts interpretive signage about the various wildlife and different ecosystems that are a part  of Hart-Miller Island and also provides history on this unique, one of a kind area.

Along with regular day use amenities, boaters and beach-goers can now rent bicycles to ride around the south cell. Visitors will be able to take binoculars and bird guides to explore the many species of birds that migrate to the island, which has become well known for its abundant bird population. There are also many other plant, insect and wildlife species to encounter. Staff on the island will also have light concessions for sale such as sodas and snacks. Hart-Miller Island is a must see for those who want to get away from it all.

Recent History

Originally part of a peninsula that extended from Edgemere, the two islands, Hart and Miller were joined by the construction of a dike in 1981. Until 2009, the impoundment was filled with dredge material from the Baltimore Harbor and surrounding tributaries. In recent years, Hart-Miller Island has become a recreational haven for boaters in the northern Chesapeake Bay.
