Union Pass is a maintained dirt road connecting the town of Pinedale to Dubois (the locals pronounce it "dew-boys"). This route showcases many mountain vistas that the Teton National Forest is known for, including Gannett Peak, the highest point in Wyoming, and numerous lakes and streams. This is a great trail if you want to see this special area via dirt instead of asphalt. Any passenger vehicle can handle Union Pass but might be bumpy without airing down your tires.
