Northeast Wyoming is easy to drive and easy to underestimate. Keep fuel in the tank, download what you need and give every leg more time than the map promises.
Getting here
I-90 is the main east–west corridor. Most travelers approach Devils Tower from Moorcroft to the south, Sundance to the southeast or Belle Fourche and Hulett to the north.
Best time to visit
Late spring through early fall offers the broadest access and the most open visitor services. Summer brings the most predictable availability and the largest crowds. Spring and fall can be beautiful but variable; winter requires a flexible weather plan.
Weather and road conditions
Conditions can change quickly. Check the National Park Service, the Wyoming Department of Transportation and a reliable local forecast before driving. Back roads may be muddy, snowy or unsuitable for your vehicle even when highways are clear.
Cell service and navigation
Download maps before leaving town. Coverage can be inconsistent around the monument, in the Bearlodge Mountains and on rural highways.
Fuel, food and water
Top off in Sundance, Moorcroft, Hulett, Belle Fourche or another full-service town. Carry water and a snack even on a simple day trip. Seasonal hours can leave fewer options than expected.
