The Coolest Underground Attractions in Arizona

Arizona boasts stunning natural beauty, from its majestic mountains to its sprawling deserts and lush forests. However, beyond its surface charm lies a trove of captivating underground attractions waiting to be explored. Venture beneath the earth’s crust to discover a world of caves, mines, bunkers, and tunnels that add a thrilling dimension to Arizona’s allure. Here’s a glimpse into some of the most captivating underground attractions in the state:

Kartchner Caverns State Park

Nestled within Kartchner Caverns State Park lies a breathtaking underground marvel: one of the world’s most remarkable and well-preserved cave systems. Discovered by two amateur cavers in 1974, these caverns boast an array of stunning formations, including stalactites, stalagmites, and helictites. Guided tours offer visitors the chance to explore two sections of this subterranean wonderland: the Rotunda/Throne Room and the Big Room, where rare wildlife like bats and spiders dwell amidst the geological splendor.

Titan Missile Museum

History and military enthusiasts won’t want to miss the Titan Missile Museum, the sole surviving site among 54 Titan II missile silos deployed during the Cold War. Housed within a former missile complex operational from 1963 to 1987, the museum provides insights into the era’s technology and the lives of the crew members who manned the site. Visitors can experience a simulated launch sequence in the control room and view the authentic Titan II missile in its original launch duct.

Grand Canyon Caverns

Near the Grand Canyon National Park, the Grand Canyon Caverns beckon with their expansive underground chambers—the largest dry caverns in the United States. With a constant temperature of 56 degrees Fahrenheit, these caverns hold a rich history dating back to their use as Native American shelters and burial grounds. Today, visitors can embark on various tours and activities, including the Explorer Tour, Wild Tour, Ghost Walk, and Overnight Stay, to delve into the caverns’ captivating depths.

Colossal Cave Mountain Park

For those drawn to tales of adventure and mystery, Colossal Cave Mountain Park offers an enticing destination. Home to one of Arizona’s largest cave systems, this park boasts over 5 miles of mapped passages steeped in legend. Visitors can choose from a range of tours, including the Classic Tour, Ladder Tour, Wild Cave Tour, and Candlelight Tour, each unveiling the cave’s storied past and geological wonders.

Phoenix Tunnels

Delve into urban intrigue with a journey through the Phoenix Tunnels, a labyrinthine network beneath downtown Phoenix. Constructed in the 1920s and 1930s for utility and infrastructure purposes, these tunnels served as air raid shelters during World War II and clandestine escape routes during the civil rights era. While primarily used for maintenance and storage today, select sections, such as those connecting the Phoenix Convention Center, Hyatt Regency Hotel, and Symphony Hall, offer glimpses into the city’s subterranean history.

Arizona’s underground attractions promise a blend of natural wonder, historical intrigue, and urban exploration.
