Located on the grounds are the Morven Park Mansion, the Winmill Carriage Museum, formal boxwood gardens, miles of hiking and riding trails, and athletic fields.

The park is also home to the Museum of Hounds and Hunting of North America with displays of art, artifacts and memorabilia about the sport of foxhunting.

The Westmoreland Davis Memorial Foundation operates Morven Park, which is a 501c3 nonprofit organization supported by contributions from donors.

Judge Swann's son, Thomas Swann Jr., began a remodeling program around 1850, using the Baltimore firm of E.G. Lind and William T. Murdock as architects, converting the Palladian house to the Italianate style with four towers, including one that was five stories tall, stated by The Buildings of Virginia to resemble Queen Victoria's Osborne House on the Isle of Wight.

He and his wife were the last private owners of the estate, which is now run as a nonprofit organization that raises money to keep the park open to the public.
