Caribou-Targhee NF OHV

The Caribou-Targhee National Forest encompasses 3 million acres of eastern Idaho and western Wyoming, covering the Teton foothills, the Island Park caldera, the Henrys Lake country, and the Bear River Range in Caribou County, the most geologically dramatic national forest in the northern Rocky Mountain West. The forest OHV trail network spans three major riding zones: the Island Park area (7,000-foot volcanic plateau south of Henrys Lake, bordering Yellowstone National Park), the Teton Valley foothills (the western slope of the Teton Range above Driggs and Victor, with views directly into the Teton peaks), and the Big Springs and Warm River corridors that thread through the forest's interior. Each zone has distinct character. Island Park is rolling plateau riding through lodgepole pine forest with meadow openings and the geothermal features that signal the Yellowstone hotspot beneath; the Teton foothills provide the most visually dramatic setting of any Idaho OHV area with the Teton peaks forming the eastern horizon on every ridge traverse; the Big Springs and Warm River areas follow the headwaters of the Henry's Fork of the Snake River through aspen-lined canyon terrain. ATVs, UTVs, dirt bikes, and full-size 4x4s on appropriate routes are all accommodated across the forest's designated motorized corridor. Idaho OHV registration required. The Ashton/Felt Ranger District office (208-652-7442) manages current trail designations and seasonal closure information across the Island Park and Teton foothills areas.
