Ayres Natural Bridge Park is nestled in the bottom of a stunning red-rock canyon. This beautiful park houses one of only three natural bridges in the United States with water beneath. If you enjoy history bites, you’ll be surprised to know that the Indigenous People who first inhabited these lands believed an evil spirit lived below this bridge.

If dinosaurs are your thing, you’ll love the Tate Geological Museum. Founded in 1980, it is one of a small number of geology and paleontology museums in Wyoming.  The Tate houses a collection of over 6000 fossil and mineral specimens, including dinosaurs and Dee the Mammoth, an 11,600-year-old Columbian Mammoth who lived in the American West during the Ice Age.

It’s possible you might know this place for the Teapot Dome Scandal. But, setting aside the political issues, this is a great stop to admire the geological processes of nature.
