Seven of the Hudson River’s original 14 lighthouses (including the Statue of Liberty) survive, and on Saturday, September 22 you can visit the four northernmost ones on an all-day boat tour. The Spirit on Hudson, a replica of a Mississippi River paddlewheeler, will depart Hudson at 7:30 a.m. and wend her way downriver, making stops at guided tours of the lighthouses at Athens, Saugerties, Kingston and Esopus Meadows.
