Trail riding is riding outdoors on trails, bridle paths, and forest roads, but not on roads regularly used by motorised traffic. A trail ride can be of any length, including a long distance, multi-day trip. It originated with horse riding, and in North America, the equestrian form is usually called "trail riding," or, less often "hacking." In the UK and Europe, the practice is usually called horse or pony trekking.
Often, horses under saddle are subject to the same regulations as pedestrians or hikers where those requirements differ from those for cyclists. In most states, horses are classified as livestock and thus restricted from areas such as the right of way of the interstate highway system, though generally permitted to travel along the side of other roadways, especially in rural areas.
Rail trails, which are redeveloped disused railways converted into multi-use trails, often provide invaluable trail riding areas in many parts of the world. A bridle path, also called a bridleway, equestrian trail, horse riding path, bridle road, or horse trail, is a trail or a thoroughfare that is used by people riding on horses, though such trails often now serve a wider range of users, including equestrians, hikers, and cyclists. Such paths are either impassable for motorized vehicles, or vehicles are banned. The laws relating to allowable uses vary from country to country.
