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.

Day-Use Opportunities

Hart-Miller Island, Hawk Cove and Pleasure Island are open year-round. Water supply and restrooms are available at the main camping area on Hart-Miller Island; however, these facilities are only available May through September. There are opportunities to hike, picnic, fish and bird-watch. More than half-a-mile of sandy beach invites swimming, beach-combing and sunbathing. An observation platform that provides great views of the marsh is open to the public from May through September. At the close of the day, the island is closed to everyone except registered campers. For your protection, glass containers are prohibited on the Island.

Please note that most of Hart-Miller Island is closed to the public. While the island is no longer receiving dredge material, until further notice only the small portion on the west side of the island that includes the main camping area, restrooms, water supply and beach is open to the public. All of Hawk Cove and Pleasure Island are open to the public.


Camping is available from May 1-September 30. Hart-Miller Island State Park offers 22 campsites available on a first-come, first-serve basis. There are 6 campsites at the main camping area on Hart-Miller Island, 11 sites at Hawk Cove, and 5 sites on Pleasure Island. All sites have a picnic table, lantern post and campfire grill.

Campfires may only be built in the fire rings provided.

Alcohol Policy

Alcohol is prohibited in all areas of Hart-Miller Island, Hawk Cove and Pleasure Island.

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 2012, 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.

Future Plans

Much of Hart-Miller Island State Park remains in developmental stages. The completion of the dike will bring new opportunities for land use of the Island.
