Smith Island is accessible only by boat. Passenger ferries run from Crisfield on Maryland's Eastern Shore, with seasonal and weather-dependent service from other Chesapeake ports. Schedules can change with tides, weather, and local demand, so confirm departure and return times before treating it as a day trip.
There is no bridge, no airport, and no car rental on the island. Bring what you need for the day, including cash if you plan to eat or shop at small local businesses.
