What are the hours of the museum in Ward Pound Ridge?

Ward Pound Reservation has over 4,000 Acres, beautiful hiking trails (you can bring your dog, but must leash) and horse trails as well. It is open 7 days a week from 8 A.M. until dusk. The Trailside Nature Museum is open Mon.-Fri. 9 A.M. - 4 P.M. Their childrens educatonal programs are wonderful, especially Stream Study, which my children loved!
