Union Pass Historic Route

Union Pass sits at 9,210 feet on the Continental Divide, marking one of the lowest crossings of the Divide in Wyoming. This 35-mile route follows the historic path used by Jim Bridger and other mountain men starting in the 1820s, later becoming a crucial link for settlers and freight wagons heading to the Pinedale area and Jackson Hole. The road passes through diverse ecosystems from sagebrush flats to alpine meadows, with excellent wildlife viewing opportunities for moose, elk, and the occasional grizzly bear.

Moderate difficulty requiring high-clearance 4WD due to rocky sections and potential snow at the pass even in summer. The route is typically accessible June through October, though early and late season can present snow challenges. No services exist along the route, so carry extra fuel and water. Multiple dispersed camping opportunities exist on both sides of the pass. This is a perfect introduction to Wyoming backcountry with manageable challenges and rich historical significance without extreme technical demands.
