Fodor's Expert Review Sweetwater County Museum
Green River
Free
Learn about the history of southwestern Wyoming in this renovated post office in downtown Green River. Permanent exhibits go in-depth about the Shoshone and Ute tribes who once lived here, as well as the cowboys, explorers, railroad workers, miners, and fur traders who later called the area home. Sweetwater County hosted the first Rocky Mountain Rendezvous in 1825, and several emigrant trails passed through these parts, including the Oregon, California, and Overland.
