Ten miles northeast of Convoy Point and about 12 miles south of the Cape Florida Lighthouse on Key Biscayne, this key once was owned by the late Mark C. Honeywell, former president of Honeywell Company, and is on the National Register of Historic Places for its 10 historic structures. A half-mile hiking trail curves around the island's south side. Climb the 65-foot-high ornamental lighthouse (by ranger tour only) for a panoramic view of Miami or check out the cannon from the HMS Fowey. There's no freshwater, access is by private boat only, and no pets are allowed. Only portable toilets are on-site, with no sinks or showers. A $20 fee for overnight docking (6 pm to 6 am) covers a campsite; pay at the harbor's automated kiosk.
