Meet at the Croton-Harmon Metro-North train station for a leisurely 7-mile loop. The walk will cross the mouth of the Croton River on the Route 9 bridge walkway, proceed north on the Old Croton Aqueduct to the historic Croton Dam, and return to the train station via Village of Croton-on-Hudson trails and shady streets. Highlights include views of the scenic Croton River Gorge with short detours to the river shoreline; and vistas of the Croton Reservoir from the top of the Dam and its unique spillway/natural waterfall; and crossing historic Quaker Bridge. The leader will relate history of the Dam and the Aqueduct (completed in 1842 to bring water to New York City) and local lore along the route. Enjoy short lunch (bring your own) in Croton Gorge Park at the foot of the Dam. Expected completion time is 1:30 pm. Heavy rain cancels.
