Beautiful park which the New Croton Dam is part of. This is a must do/see. The Dam and falls are spectacular. Picnic in the park and walk the trails. One trail takes you to the top of the Aqueduct, but the walk might be too strenuous for those with physical problems as it goes uphill. The trail walk is well worth it. The view looking down from the Aqueduct is absolutely gorgeous. A $5 parking fee is charged in season, but is free after Labor Day and an Autumn day is perfect to visit. It was a warm and beautiful Fall day when we visited so it was very crowded so much so that there was a someone to park cars so arriving earlier might be a better option than after lunch.
