Spectacular cave formations reward visitors on a two-mile, guided tour.

Even though the fantastic geological formations inside the Caverns of Sonora are the primary attraction, consider also that the cave is cool in the summer: a steady 71 degrees. And this year, the Caverns celebrate 50 years of public tours. As one expert, George Veni, Executive Director of the National Cave and Karst Research Institute in Carlsbad, New Mexico, explains, these caverns, located in the southwest quadrant of the state, “are internationally recognized as the most beautiful show cave on the planet.”

You’ll find the Caverns of Sonora 15 miles southwest of Sonora, off Interstate 10. The best driving route is to take Exit 392 south onto RR 1989 (Caverns of Sonora Rd.), and follow the road signs. The Caverns open daily, year-round, except Christmas Day; guided tours are offered throughout the day. Special “adventure tours,” photography tours, and large-group tours must be arranged in advance. The visitor center offers fossils, rocks, books, and jewelry, as well as snacks (including homemade fudge). RV and tent camping are available, along with potable water, electricity, and restrooms with showers.

Caverns of Sonora staff will host a public celebration in July to mark the 50th anniversary of the first public cave tours. For updates on the event or details about the Caverns, including admission fees, call 325/387-3105 or 325/387-6507;
