Equestrian When you go out on a trail in New Hampshire on horseback, your options are almost limitless. With the help of volunteer organizations throughout the state, there are more and more trails built to sustain horseback riding in New Hampshire's State Parks, Forests, and on Recreational Rail Trails. Not all trails and areas are open and suitable for horseback riding, and many parking areas may not accommodate large trailers. Please check with the Bureau of Trails before you ride. To ensure a pleasurable and safe visit for both equestrians and park visitors, please take the time to familiarize yourself with the Division of Parks and Recreation's Rules.
