Vanderbilt Mansion National Historic Site was designated on December 18, 1940, and a few years later on October 15, 1966, added to the National Register of Historic Places. The historic site encompasses a total area of 212 acres of land that is located in the Hudson River Valley in Hyde Park which is 90 miles north of New York City and 70 miles south. The park is accessible using US Highway 9.
The main attraction of the historic site that makes it a great place to visit is the 54-room palatial mansion built by Frederick W. Vanderbilt who was a grandson of Cornelius Vanderbilt who was an American business industrialist and philanthropist that made his wealth in railroads and shipping ventures.
This magnificent, Beaux-Arts architecture style building that was built between 1896 and 1899 is an excellent example of how 19th-century millionaires constructed their homes. When at this historic site, you can also get to enjoy picnicking, hiking, and guided tours of the property.
These activities are made possible by the park's management through several facilities and amenities including a visitor center, restrooms, a picnic area, and an exhibit. Dogs are allowed into the Vanderbilt Mansion National Historic Site but definitely not into this specific building or into other historic buildings or properties at the landmark site.
Furthermore, for areas of the park where dog owners are allowed to visit, dogs should be kept on a leash at all times. When your tail-wagger is not on a leash, then they should be in a secured enclosure. Also, dog owners are expected to clean up after their dog right away and dispose of solid waste in the proper manner. As such, it is a good idea for a dog owner to bring with them some disposable poop bags for their pet.
