Calling all history buffs. Visit landmarks such as, KyKuit (the Rockefeller Estate), Philipsburg Manor, Washington Irving’s Sunnyside, Van Cortlandt Manor, and Union Church of Pocantico Hills. Most locations do allow self-guided tours, but tickets can be purchased for guided tours of each location. Best part is, several of the landmarks are located near each other, so guests can visit more than one location in a day.
