Watford City to Riverton Road Trip: Unmissable Stops & Route Guide

Driving from Watford City, ND, to Riverton, WY, is a 580-mile journey through the heart of the Northern Plains, traversing North Dakota, Montana, and Wyoming. The route roughly follows US-85 south and then US-16 west, crossing the Missouri River at the Garrison Dam and ascending onto the high plains.

This drive is a study in geological time, passing through the Badlands of the Little Missouri River and the Bighorn Basin, where ancient rock layers reveal 500 million years of history.

The following guide provides a comprehensive breakdown of the drive, highlighting key stops, logistics, and practical tips, so you can focus on the journey itself.

Driving Considerations

The most direct route begins on US-85 south from Watford City, passing through Belfield, ND, and continuing through Montana, eventually joining I-90 near Buffalo, WY. From there, take US-16 west to reach Riverton.

Expect sparse services between towns; plan to fill up when crossing the Montana border, as gas stations can be 100 miles apart.

• Fuel cost for a mid-size car: approximately $75 at current prices.
• There are no toll roads on this route.
• Cell service is spotty in remote areas; download offline maps.
• The route is well-maintained, with the worst sections in the Badlands of North Dakota.

Travel Essentials

Before departure, check road conditions in Wyoming, which can be unpredictable due to snow in mountain passes.
