traverses the eastern side of the mountain from Torrey through Boulder and on to Escalante. A series of unpaved backcountry roads and jeep trails provide access to the top during the brief snow free time, which is usually only a few months from July to September. These jeep trails were originally created as the main route for wagons traveling between Escalante and Boulder. The trail was upgraded to a road in 1920 when the Ohio Drilling Company created a route to Wagon Box Mesa. A famous road on the mountain, Hell's Backbone Road, forks from Scenic Byway 12. Hell's Backbone then runs west toward Posy Lake/Pine Creek Road. The road eventually winds back to the town of Escalante which allows travelers to complete a 38-mile loop.
Fly fishing
Boulder Mountain is routinely held in high regard by Utahan's as a fisherman's paradise. Fishing opportunities began on the mountain in the 1950s when juvenile fish were carried via horseback and planted in the area's high alpine lakes and streams. Brook trout are the prominent species stocked on Boulder Mountain. Colorado River Cutthroat are the fish species native to the area. In 2014, a committee consisting of anglers and local residents convened to determine the future management of the fisheries on Boulder Mountain. This committee assisted the Utah Division of Wildlife Resources in resolving the issue of overpopulating brook trout in the alpine lakes of Boulder Mountain. Based on the discussion, 35 percent of the lakes would be managed for trophy brook trout. The management plan categorized each of lakes into ten different sections: North Creek, North Slope, South Slope, East Slope, West Slope, Boulder Top, Griffin Top, and Escalante Mountain. The management plan introduces splake, tiger, and cutthroat trout to the waters that the committee deemed appropriate. Colorado cutthroat populations have steadily decreased since the introduction of brook trout to the area. Emphasizing the importance to re-establish a healthy population of native trout to the area sterile brook trout, along with other sterile trout species, such as tiger and splake trout, were introduced to increase fishing opportunities.
The mountain is home to some of the biggest elk in the state of Utah, consistently producing some of the largest bull elk during the hunt each fall. The mountain is also known for mule deer. Predators are also prevalent, mountain lions and black bears are commonly seen throughout the area.
