Use of Rocky Mountain Horses: Rocky Mountain Horses are used often on trail because of their surefootedness and smooth gait. They are also shown in open gaited horse shows, competing with Tennessee Walking Horses, Missouri Fox Trotters and other gaited breeds. Shows just for Rocky Mountain Horses feature classes in trail pleasure, show pleasure, western pleasure, pleasure driving, trail obstacle, pole bending, showmanship, equitation, bareback, costume, lead line and conformation.
