Butch Cassidy was a well-known character around Thermopolis, although not by any means the only outlaw who favored this rugged country. Visitors who want to relive a Wild West getaway can join the annual Outlaw Trail Ride in August, and journey 100 miles up through the dry, hidden canyons of Hole-in-the-Wall country. Only about 100 people can participate in the weeklong event, and it's popular, so book well in advance. You must BYO horse and sleep on the ground.
