Treat your family to some of Yellowstone’s special experiences. In summer, go “western” by saddling up for one- or two-hour guided horseback trail rides (minimum age 8; minimum height 48 inches) through valleys and alongside creeks. Try a cookout dinner and opt to arrive by horseback or by wagon. Take a stagecoach ride in an 18-passenger vehicle that’s a replica of the ones used by Yellowstone’s early visitors.
