Gardiner, MT to Evanston, WY: A Scenic Road Trip Guide

This 400-mile journey from Gardiner, Montana, the North Entrance to Yellowstone National Park, to Evanston, Wyoming, a historic railroad town near the Utah border, traverses the Greater Yellowstone Ecosystem and the high desert of the Wyoming Basin. The route follows US-191 South and US-287 East to Dubois, then US-26 East to Riverton, and finally US-287/US-20/US-26 to Muddy Gap, where it joins I-80 West to Evanston.

Driving time is roughly 7–8 hours without stops, but plan for at least 10–12 hours to absorb the scenery and attractions. The route's elevation ranges from 5,300 feet in Gardiner to over 8,000 feet at South Pass, so expect variations in weather and temperature.

This route is family-friendly with several rest areas and short hikes. Yellowstone's North Entrance is a top attraction, but for a break, pull off at the Wind River Canyon, a narrow gorge with excellent photo ops. The Red Desert's sand dunes are a hit with kids, though remote.

For pets, keep them leashed at all times due to wildlife. Many motels along the way, like the Riverton Budget Inn, accept pets. Fatigue can creep in on long stretches; plan stops every 2 hours. Rest areas are well-maintained, but in winter, some close. Always carry water and blankets.
