The Hudson Valley is very rich with history. The region contains historic sites such as the Rockefeller Estate, Washington Irving's home, and the Philipsburg Manor. The Philipsburg Manor is a 17th/18th century farm that was once owned by a Dutch family. At one point, the Philipsburg Manor was the biggest property and milling complex in New York. Today, it has become a working farm, maintained to educate the public. Once you start the guided tour, you'll be greeted by costumed historians who will take you through the various parts of the farm, providing you with the history and explanation of the agricultural processes. This is a must see for history buffs. However, you don't need to be one to appreciate this place.
If you are looking for an easy day trip to escape the hustle and bustle of the city, this is what the doctor ordered. The natural beauty of the valley will ease any tensions. You can get to the Hudson Valley by catching a train at the Grand Central Station or there is also a boat tour that comes to the location as well.
