Located in the heart of the Hudson Valley, just 40 miles from New York City, the Arden House is the country’s first – and still among its premier – conference center properties. An elegant 100,000 square foot+ mansion set on the top of Mount Orama, Arden House is surrounded by 450 acres in the protected Palisades Interstate Park.

This beautiful home was built in 1909 for Ned and Mary Harriman by architect Edward Adams (Eddie) for their son W. Averell Harriman (1891-1986). Unlike many other Gilded Age estates, this was intended to be used as a private residence and is unique for its American expression of elegance and its setting within the secluded 450-acre rambling landscape.

Today the Arden House continues to serve as an important cultural, historical and environmental asset for the Village of Arden, Ardentown and Ardencroft, the state of Delaware and the greater New York metropolitan area. Arden House is also one of the nation’s finest architectural and historic treasures – an elegant mansion in the tradition of European country houses surrounded by rolling woodlands, breathtaking views and a private 125-acre lake.

The 111th Arden Fair was held on Saturday, Sept. 1, 2024.

The Arden Club is a non-profit organization whose proceeds from the Fair help maintain the Arden Gild Hall, where the public enjoys concerts, musicals, plays, dances, Saturday evening dinners and other programs throughout the year. The Arden Pool is an additional amenity for Club members, with a fee and refundable deposit required to join the Swim Club. See the Swim Club website for more information.
