Route description

Leave Idaho Falls north on US-20 to Ashton, about 80 km away, and turn onto ID-47, the Mesa Falls Scenic Byway. The road passes through forest to Lower and Upper Mesa Falls on the Henrys Fork. Upper Mesa Falls has boardwalks to the brink. The byway then rejoins US-20 a short drive south of Harriman State Park, a wildlife refuge with trumpeter swans and moose along the river.

US-20 continues north through Island Park to West Yellowstone, a busy gateway town with fuel, RV parks and supplies. Yellowstone’s main roads are generally open from late April to early November. From the West Entrance, follow the Madison River to Madison Junction, then turn north to Norris Geyser Basin, where Steamboat Geyser occasionally erupts. Old Faithful lies the other way, 25 km south of Madison.

From Norris, it is 19 km east to Canyon Village and the Grand Canyon of the Yellowstone. Drive the South Rim Drive to Artist Point and the North Rim Drive to the Brink of the Lower Falls. Canyon Campground takes reservations, and it is a good base for exploring the area. South of Canyon, the road runs through Hayden Valley, where bison often cross the road.

Past Mud Volcano, the road reaches Yellowstone Lake at Fishing Bridge, where the RV park only takes hard-sided vehicles because of bears. Continue along the shore to West Thumb Geyser Basin, then return to Fishing Bridge and take the East Entrance road over Sylvan Pass. It descends through the Wapiti Valley past Buffalo Bill Dam to Cody, about 160 km from West Thumb.
