Tour the International Museum of the Horse, run in cooperation with the Smithsonian Institution. In addition to viewing the many exhibits on the ancient relationship between people and horses, you'll also be able to get close to real horses. There's a Parade of Breeds, horse-drawn carriage rides, and a 45-minute trail ride around the park—suitable even for those who've never ridden before. The park also houses the American Saddlebred Museum (that's the breed used for dressage). Tours of nearby horse farms are available for an extra fee.
