Cheyenne to Green River Drive: Scenic, Safe, and Worth It

At the start of the Transcontinental Railroad's golden spike ceremony, Cheyenne was a rough-and-tumble frontier town, but today it's the gateway to a drive that showcases Wyoming's geological drama. This route follows I-80 west for 284 miles, climbing from the high plains (6,062 ft) to the Continental Divide at 7,084 ft, then dropping into the Green River Basin.

Expect a journey of about 4 hours and 20 minutes of pure driving, but plan for at least 6 hours to enjoy the sights. The highway's straight sections and vast horizons can lull you into a trance, so schedule breaks. This guide helps you find the best stops Cheyenne, WY to Green River, WY has to offer.
