Jackson to Hamilton Road Trip: Wyoming to Montana Guide

The route from Jackson, Wyoming to Hamilton, Montana covers approximately 300 miles via US-191 and US-287. A notable geography quirk: you traverse the Continental Divide twice, at Togwotee Pass (9,658 ft) and near Monida Pass (6,820 ft). This alpine-to-valley transition defines the journey.

Estimated driving time is 5.5 to 6.5 hours without stops, but allocate a full day to enjoy the landscapes. Key highways include US-191 from Jackson to Pinedale, then US-189/US-191 to Daniel Junction, US-287 through Dubois and the Wind River Reservation, and finally US-287 to I-15 at Monida, then MT-287 to MT-43 and MT-551 into Hamilton.
