The RiverLink Ferry opened March 1992, as a passenger ferry service that crossed the Delaware River connecting the Camden Waterfront with Philadelphia's, Penn's Landing. The ferry operates daily from May through September, and on Fridays through Sundays in April and October. Docking at Wiggins Park, located between the Adventure Aquarium and the Battleship New Jersey, the ferry provides access to the Adventure Aquarium, Battleship New Jersey, Camden's Children's Garden, and the Freedom Mortgage Pavilion. On the Philadelphia side of the river the ferry docks at the Independence Seaport Museum, and provides access to the many attractions located at Penns Landing, including multiple city piers, and restaurants as well as Museums, the battle ship Olympia, and the submarine Becuna. Penn's Landing opened up the opportunity to exploring the historical section of Center City Philadelphia including Independence Hall, and City Hall. Round trip ticket prices range from $8 for children and seniors to $10 for adults while children under the age of four ride for free.
