Afton WY to Choteau MT: Scenic Guide, Stops & Tips

Before you leave town, note the 110-foot-tall Afton arch—the world's largest elk antler arch—spanning US-89. That quirky landmark is just a prelude to a route that climbs from the Star Valley floor (6,230 ft) to the Continental Divide at Togwotee Pass (9,658 ft), skirting the Gros Ventre and Absaroka ranges. This stretch of US-89 and US-26/287 crosses three national forests and the Wind River Indian Reservation, with a total elevation gain that directly influences both your fuel economy and your timeline.

How long to drive Afton, WY to Choteau, MT? The 525-mile route usually takes 9–10 hours of pure driving, but expect to add at least 3–4 hours for meals, fuel, and photo stops. That puts a comfortable one-way trip at a full day, so is it worth driving Afton, WY to Choteau, MT? Absolutely, but only if you intentionally choose the scenic path—the interstate alternative takes 8 hours but misses the high desert geology and Yellowstone-adjacent wildlife corridors that define this journey.

Road quality is good, but wildlife collisions and sudden weather changes are the primary hazards. From May through September, thunderstorms and hail are common in the afternoons; from November to April, anticipate snowpack on Togwotee and high winds near Choteau. Keep a sleeping bag, water, and a shovel in the trunk—you may wait out a road closure.

• Rest zones: Afton's first 4-way stop (the world's only) is at the town entrance; take breaks at Jackson's Cache Creek Trailhead and at Buffalo Bill State Park south of Cody.
• Family suitability: Kid-friendly stops include the National Museum of Wildlife Art (free for under 18) in Jackson, the Wyoming Dinosaur Center in Thermopolis, and the Cody Firearms Experience. An under-5 can enjoy a splash in Hot Springs State Park pools.
• Pet-friendly framework: Most hotels and motels along the route accept pets (ask about fees). Designated pet areas are at Wind River Canyon viewpoints and at the forks of the Shoshone River near Cody; always keep pets leashed due to wildlife and fragile vegetation.
• Hidden off-route spots: 30 miles south of Dubois, off US-287, the Pinnacle Buttes in the Wind River Indian Reservation offer colorful hoodoos and solitude, but require a recreation permit from the Shoshone and Arapaho tribes.
• Fatigue management: The longest drive between services is Dubois to Thermopolis (~2 hours); plan a stretch stop at the scenic overlook over Boysen Reservoir at milepost 144. Switch drivers every 2 hours if possible.

From Afton, the climb to Salt River Pass offers a panorama of the Salt River Range; east of Jackson, the Gros Ventre Slide area shows the largest known landslide in the U.S. (1925), an impressive scar on Sheep Mountain. Near Dubois, the Wind River canyon walls reveal ancient sea floors, and at Thermopolis, you'll hit the world's largest mineral hot spring—Hot Springs State Park. Local commerce thrives at small ranches selling homemade jam and trading posts on the Wind River Reservation—stop at the Fort Washakie museum for Shoshone and Arapaho history.

UNESCO World Heritage Sites are not on this route’s direct path, but two are within a 90-minute detour: Yellowstone National Park (entrance fee $35/vehicle) and Grand Teton National Park. If you're considering a side trip, the South Entrance to Yellowstone is 60 miles from Jackson. In Cody, the Buffalo Bill Center of the West offers five museums under one roof—a deep dive into Plains Indian cultures and natural history.

Major highways are paved and well-maintained year-round, but winter conditions between October and April demand all-wheel drive and traction tires for Togwotee Pass. Summer sees clear roads but occasional construction delays. Cell service is sporadic west of Lander and north of Cody, so download offline maps. Fuel stations cluster every 60–80 miles along the corridor; the most isolated stretch is between Dubois and Thermopolis—127 miles—so fill up in Dubois.

• US-89 from Afton to Jackson is a winding canyon with wildlife crossings (elk, moose).
• US-26/287 through Wind River Canyon is a 15-mile geological wonder; reach it after Thermopolis.
• Fuel in Afton: ~$3.50/gal; in Dubois: ~$3.80/gal; in Cody: ~$3.60/gal; in Choteau: ~$3.40/gal (prices as of 2025).
• Roadside dining is sparse between Dubois and Thermopolis—carry snacks.
