1 Best Sight in Cody, Sheridan, and Northern Wyoming, Wyoming

The land that became Wyoming's first state park in 1897 had always been sacred to Native Americans because of its healing natural hot springs. You can partake of these waters by soaking indoors or outside at the free 104°F mineral pools at the State Bath House, which is a central feature of this impressive 1,104-acre park that's also home to two waterparks (which charge admission fees) with more indoor and outdoor hot mineral pools, waterslides, and other amusements. You can also hike or bike on 6 miles of trails, view the park's sizable bison herd, traipse across a swinging suspension bridge that traverses the Big Horn River, offering views of the dramatic travertine mineral terraces.
