Sheridan to Moscow Road Trip: Ultimate Guide

The 530-mile route from Sheridan, Wyoming to Moscow, Idaho traverses the high plains of Wyoming, crosses the Bighorn Basin, and ascends the Rocky Mountains before descending into the rolling Palouse. A little-known fact: the section from Sheridan to Cody follows the old Bozeman Trail, a 19th-century emigrant route to Montana goldfields, now paved as US-14 and US-16.

The journey takes about 8–9 hours of pure driving time, but with scenic detours and stops, plan for at least two days. The route is worth driving for its dramatic transitions: from sagebrush steppe to alpine forests, volcanic badlands, and fertile wheat fields.

Curated insights on how to find the best stops and hidden gems between cities can transform your trip. Below are essential logistics to prepare for the journey.

Safety factors: wildlife (elk, bison, deer) frequently cross roads in Yellowstone and Montana. Drive at dusk with caution. Police presence is moderate; speed traps near small towns. Road conditions: I-90 is well-maintained; US-14 may have frost heaves in spring.

• Fatigue management: rest zones exist at pullouts near Yellowstone Lake and along I-90 at Whitehall (Sheridan rest stop, mile marker 134).
• Family suitability: Yellowstone is highly kid-friendly; junior ranger programs available. Bozeman has a children's museum.
• Pet-friendly: pets are not allowed on Yellowstone trails or boardwalks; kennels available in West Yellowstone. Many Montana hotels allow dogs.

For culinary infrastructure, Cody has the Irma Hotel's buffalo burgers, while Missoula's 'Upside Brewery' serves food truck fare. Between West Yellowstone and Bozeman, the Roadhouse Café in Big Sky offers hearty breakfast. In Moscow, the 'Black Cypress' features wood-fired pizzas. For local commerce, check out the handmade leather goods at Diamond & Gold in Cody or the Moscow Farmers Market on Saturdays.

Primary highways: US-14 West from Sheridan to Cody, then US-16/US-20 through Yellowstone (summer only). From West Yellowstone, take US-191 to Bozeman, then I-90 West to Missoula, and US-93 South to Moscow. Winter closures at Yellowstone's East Entrance (early Nov to late Apr) force a detour via I-90 through Butte and Missoula, adding about an hour.

• Gas stations are sparse between Cody and West Yellowstone (90 miles). Fill up in Cody.
• Cell service is unreliable in Yellowstone and parts of Montana. Download offline maps.
• Road quality: excellent on interstates, fair on US-14 and Yellowstone roads (potholes possible in spring).
• Speed limits: 70 mph on I-90, 55-65 on US highways, 45 in Yellowstone.

Fuel and route economics: average gas price along route is $3.50/gal (as of 2025). Budget $90-$120 for fuel for a midsize car. Tolls: none. National park entry fee: $35 per vehicle (valid 7 days). Lodging: average $120-180/night in summer; book ahead in Yellowstone and Missoula.

From Sheridan, drive through the Bighorn Basin's high desert, punctuated by red rock cliffs and sage. Near Cody, the Shoshone River Canyon offers dramatic limestone walls. Yellowstone's geothermal features—Old Faithful, Grand Prismatic Spring—are must-sees.

• Best stops: Buffalo Bill Center of the West (Cody), Mammoth Hot Springs, Lamar Valley (wildlife).
• UNESCO World Heritage Sites: Yellowstone National Park (designated 1978).
• Hidden off-route spot: the ghost town of Kirwin, Wyoming (accessible via forest roads near Meeteetse)—an abandoned mining camp.

After Yellowstone, the Gallatin River Canyon on US-191 offers whitewater views and fishing access. Bozeman's Main Street has farm-to-table restaurants and craft breweries. Further west, I-90 crosses the Continental Divide at Homestake Pass (elevation 6,329 ft). Near Missoula, stop at the smoking gun: the 'M' trail for panoramic views. Into Idaho, the Palouse hills roll like green waves, with grain silos and farm stands selling huckleberry jam and fresh apples.
