East End Seaport and Marine Foundation
A former Long Island Rail Road passenger terminal contains exhibits about lighthouses, ships, East End shipbuilding, and yacht racing. The museum also hosts events, including the annual Maritime Festival. Several times throughout the season, for an additional fee, you can take a 6-hour day cruise or a 3- to 5-hour sunset cruise passing by 4 to 6 lighthouses and stopping to visit the historic "Bug" lighthouse. There's also a separate 1½-hour excursion that goes only to the "Bug."
