Parking for this cache is the same as for the New Croton Dam Adventure Lab, on Croton Dam Road, where there is space for aproximately twenty-five cars. Please note that this parking area gets filled quickly during warmer weather and on weekends. You can also park in Croton Gorge Park (below the dam) and use a trail to hike up to the dam, but there is an entrance fee collected from Memorial Day to Labor Day and on weekends in May and September.
