Fodor's Expert Review Buffalo Bill State Park
About 6 miles west of downtown on U.S. 14, you'll pass through the Shoshone Canyon Tunnel (the state's largest, at 2.8 miles) and emerge at the northeast end of Buffalo Bill Reservoir, which was formed in 1910 by the construction of a 350-foot-tall dam. The reservoir, which is popular for boating and fishing, forms the heart of Buffalo Bill State Park, which also has a campground and picnic area. Just after exiting the tunnel, you can also stop by the visitor center operated by the U.S. Bureau of Reclamation, where you can peer over this immense dam from a viewing platform, and watch a film and explore exhibits on this impressive feat of engineering and the region's natural and human history.
