02 Sep Arizona’s Hidden Wonders: 4 Cave Tours to Explore

Arizona is full of stunning natural landscapes, from the red rocks of Sedona to the giant cacti of Tucson’s Saguaro National Park. But some of the most awe-inspiring experiences lie beneath this breathtaking surface. Exploring Arizona’s natural caves is an exciting and unusual adventure! We share our favorite cave tours near Phoenix and some tips for safe spelunking.

Top Four Arizona Cave Tours Worth Seeing

1. Kartchner Caverns State Park – Benson, AZ

Kartchner Caverns, Arizona’s largest living cave system, has some of the best guided tours in Arizona. With two main tour routes, the Rotunda/Throne and the Big Room, you’ll see dramatic formations like stalactites and stalagmites, including the world’s longest soda straw stalactite. The guided tours provide an educational glimpse into a 200,000-year-old subterranean world. 

2. Lava River Cave – Flagstaff, AZ

Formed by a volcanic eruption nearly 700,000 years ago, Lava River Cave is a mile-long lava tube that is a self-guided adventure for brave explorers. Make sure to bring sturdy shoes and warm clothing, as temperatures in this cave stay between 35°F and 45°F year-round. And don’t forget to bring reliable light sources—it’s completely dark in this cave once you’re inside. In fact, it’s recommended to bring at least two sources of light (such as a flashlight and a headlamp) in case one dies out or breaks. 

3. Grand Canyon Caverns – Peach Springs, AZ

Located along Route 66, the Grand Canyon Caverns are the largest dry caverns in the United States. There are a variety of tours geared towards different age groups. After you work up an appetite spelunking, head over to The Caverns Grill for a hearty meal. If you’re planning a trip, you can even make a reservation for a charming cabin or cozy room at the inn—or sleep under the stars at the campground. 

4. Colossal Cave – Vail, AZ

Located just southeast of Tucson, Colossal Cave is one of the largest dry caves in Arizona—and in all of North America. Visitors can enjoy a 1.5-hour ladder tour that navigates narrow passages and rock bridges, or a classic 40-minute walking tour. The history in this cave is just as fascinating as its breathtaking views—legend has it that bandits used the cave as a hideout in the late 1800s. It’s a great destination for adventurers and history buffs alike. 

Safety Tips for Touring Caves in Arizona

• Wear Proper Footwear

Cave floors can be slippery, rocky, or uneven. Closed-toe hiking boots or shoes with a strong grip are essential.

• Bring Layers

Even in the heat of summer, caves stay cool. A light jacket can help you stay comfortable throughout the tour. 

• Use Reliable Lighting

For self-guided caves like Lava River, bring multiple light sources and extra batteries. Headlamps are a good idea, as they free up your hands for climbing or balancing. 

• Reserve Tours in Advance

Kartchner Caverns and Grand Canyon Caverns, in particular, are popular and often book up quickly—especially during peak travel seasons. Reserve your tour early to ensure you’re able to take the tour when you want. 

• Follow Park Rules & Conservation Guidelines

Caves are fragile ecosystems. Don’t touch formations, make sure to stay on marked paths, and listen to your guide’s instructions. Keep in mind that many parks are asking guests to take precautions to help prevent the spread of White Nose Syndrome in bats by avoiding wearing the same clothes or shoes you wore to another cave. 

• Check Accessibility & Tour Difficulty

Remember that every cave is unique. Some are well-lit with paved passages and handrails, while others require crawling, climbing, or squeezing through tight spaces. Know your limits and choose the right tour for your comfort level. 

Be Prepared with a Solid Estate Plan

Exploring caves may be exhilarating, but it’s also a lesson in preparedness. You wouldn’t walk into a pitch black tunnel without a flashlight and the right gear. In the same way, you shouldn’t attempt to navigate life’s unexpected twists and turns without an estate plan. 

Just like Arizona’s caves took millennia to form, your life’s work, savings, and legacy have been carefully crafted over time. Estate planning ensures that your wishes are protected, your family is cared for, and your legacy endures.
