Hart-Miller Island State Park

Hart-Miller Island is a 1,100-acre island located in Baltimore County on the Chesapeake Bay near the mouth of Middle River and is a must see for those who want to get away from it all. The island was originally part of a peninsula that extended from Edgemere, Maryland. The two islands, Hart and Miller were joined by the construction of a dike in 1981, and until 2009, the impoundment was filled with dredge material from Baltimore Harbor, eventually creating Hart-Miller island. In recent years, Hart-Miller Island has become a haven for boaters in the northern Chesapeake Bay, providing the public opportunities to encounter many different species of plants, insects and wildlife along with other fun recreational activities.

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. The park is well-known for its abundant migrating bird populations.
