Thermopolis to Evanston: Scenic Drive Guide & Stops

The drive from Thermopolis, WY to Evanston, WY covers about 340 miles via US-20 W and I-80 W, a route that passes through Wyoming's vast, varied terrain. Notably, this trip crosses the Continental Divide at South Pass, a historic milestone for westward pioneers.

Expect a drive time of roughly 5.5 to 6 hours without stops, but the journey offers ample opportunities to break up the distance with natural wonders and small-town charm.

This drive showcases the diversity of Wyoming's landscapes: from the red canyon walls near Thermopolis to the high desert plains, the Wind River Range, and the rolling hills of the Red Desert.

Notable natural attraction: Hot Springs State Park in Thermopolis features the world's largest mineral hot spring, with a free state bathhouse. Further west, the Wind River Indian Reservation offers scenic overlooks and cultural insights, though services are limited.

Local commerce along the route includes small-town diners and gas stations in places like Lander, a hub for outdoor enthusiasts. For a taste of local culture, stop at the Lander Bake Shop for fresh pastries or visit the Riverton Museum to learn about pioneer history.

Road safety is paramount, especially on two-lane highways where livestock may cross. Watch for wildlife, particularly deer and elk during dawn and dusk.

For families, consider a stop at Sinks Canyon State Park near Lander, where the Middle Fork of the Popo Agie River disappears underground and reappears a quarter-mile downstream. The park offers easy hiking trails and picnic areas. Another kid-friendly option is the National Museum of Military Vehicles in Dubois, about an hour north of Lander (slight detour).

Pet-friendly: Many rest areas allow leashed pets, but national parks and some state parks require pets on trails. Always carry water and waste bags.

Fatigue management: Plan rest stops every 2 hours. The rest area at South Pass offers scenic views and a break from driving. Also, the town of Rawlins, a key stop on I-80, has numerous services including hotels and fast food.

Navigating this route is straightforward: from Thermopolis, head west on US-20, which merges into US-26 near Shoshoni, then continue on WY-789 through Riverton and Lander. After Lander, pick up WY-28 over South Pass, eventually joining I-80 west toward Evanston.

• Fuel: Gas stations are sparse between Lander and Rawlins; fill up in Thermopolis, Riverton, or Lander.
• Food: Dining options are limited in small towns; consider packing snacks and a picnic lunch.
• Road Conditions: In winter, be prepared for snow and ice on South Pass; check weather forecasts and carry chains.
• Cell Service: Expect dead zones, especially in mountainous areas.
