AAA Editor Notes

Harriman State Park is 9 mi. s. on US 20 to 3489 Green Canyon Rd., following signs. Occupying the site of the 11,000-acre Railroad Ranch owned by Union Pacific Railroad investors from 1902-77, today the park is a wildlife refuge within the greater Yellowstone ecosystem. More than 20 miles of hiking, mountain biking and equestrian trails traverse the park, which is known for its spectacular summer wildflower displays. Horseback rides are offered in summer and fall, and winter draws Nordic skiers, fat tire snow bikers and snowshoers. Eight miles of the meandering Henry's Fork, one of the country's best fly-fishing streams, lie within the park's borders. The expanse encompasses woods, sage plains, meadows, streams and lakes and shelters a wide variety of wildlife, including moose, elk, bears, sandhill cranes and trumpeter swans. Note: Pets must be leashed and are allowed in day-use parking lots only. Recreational activities are permitted. Picnicking is permitted. Time: Allow 1 hour minimum.
