Each summer, the New London Maritime Society and Custom House Maritime Museum provide Sentinels on the Sound boat tours of New London Harbor as well as to our three lighthouses. U.S. Lighthouse Society members receive the same discount as NLMS members. Land tours to New London Harbor Light are offered year-round. The NLMS adopted the New London Harbor Light in 2010, the Race Rock Light Station in 2013 and the New London Ledge Light in 2014 in association with the New London Ledge Light Foundation. Stamps for all of these light are available at the Museum located at 150 Bank Street, New London, CT 06320. Phone: 860-447-2501.
