trail riding

Trail riding is riding outdoors on natural trails as opposed to riding on roads or a riding arena. The term may encompass those who travel on horses, on mountain bikes, or on motorcycles and other motorized all-terrain vehicles. Trail rides may be informal activities of an individual or small group of people, or may be larger events organized by a club. Some trail rides may even be directed by professional guides or outfitters, particularly horseback rides at Guest ranches.
