Hart-Miller Island is located in the Chesapeake Bay near the mouth of Middle River and is accessible only by boat. The western shore of the island offers safe mooring, wading and access to a 3,000-foot sandy beach. The 244-acre island is located in Baltimore County.

Accessible only by boat, Hart-Miller has a beach, observation tower, bathrooms and some primitive camping sites. Some weekends the place can get mobbed with boaters and party goers. No real trails of any sort.

You have to have a boat to get there and it's an island so no trail really.
