Comb the Cave

An unusual attraction along Historic Route 66 in Peach Springs, Arizona, takes guests deep underground for a unique tour of the largest dry caverns in the U.S.
Just 3% of the world’s caverns are dry, meaning you won’t find bugs, bats, or any other signs of life, other than the tourists, because there is absolutely no moisture in the caverns. Grand Canyon Caverns falls within that 3%, without any water seeping in.
These caverns were discovered in 1927 when a young man named Walter Peck literally stumbled into them, falling through a hole. Peck originally thought he had found gold in the caverns, but it was only iron oxide, so instead of mining, he made money by starting tours. He charged 25 cents to lower guests into the cave by a rope.
This early method was later coined “dope on a rope,” because if the person became detached from the rope or lost their light source, they were all alone in complete darkness. Today, there is a dope on a rope replica display outside of the caverns.
Guests now ride in an elevator down 21 stories to enjoy a much more comfortable tour of the caverns. There are a few different tour options to suit your needs, running from 9:30 a.m.-6 p.m. The regular tour is most popular, lasting about 45 minutes and visiting a good portion of the caverns, with views of the Cavern Grotto, Cave Motel Room, safety bunker and several selenite and limestone crystal formations.
Due to the dry conditions of the caverns, any creature that had fallen in years ago was preserved inside. Visitors will catch a glimpse of a mummified bobcat and a replica of a prehistoric beast that left scratches on the cave walls trying to get out.
The regular tour requires climbing up and down some steps, so those who are not physically able may choose to do the short tour, which is handicap accessible. The short tour lasts about 25 minutes, so it may also be a good option for those with time constraints. Children 5 and under are free on both the short and regular tours.
If you seek further exploration of the caves, you can book an explorer tour, lasting about 2.5 hours, which will take guests off the trail into deeper parts of the cave.
For an even more exciting experience, book the wild tour, which takes guests to the “Mystery Room” — the newest section of the caverns that has been seen only by a select few visitors. See GCCaverns.com/tours-activities/ for pricing and more information on the tours.
For those with paranormal curiosities there is yet another option — the ghost walk. Over the last 50 years, eight people have died or been buried on the caverns property, and guests have claimed to experience ghost sightings. This one-hour tour starts at 5 p.m. or 6 p.m., with guests being lead through the dark with EMF meters to register any possible activity in the caves.
Guests can dine on property at the Caverns Restaurant, open for lunch and dinner from 11:30 a.m.-6 p.m. And don’t forget to check out the gift shop and pick up a souvenir.
Dubbed as one of the world’s top 10 most unusual places to stay the night, the Cave Motel Room is available to sleep overnight, if you dare. Deep, dark and eerily quiet, the suite is set up with two double beds, a queen sleeper sofa, a table and chairs, bathroom, a library of books and magazines, a record player and personal lighting. It’s an experience you simply cannot find anywhere else.
If the Cave Room isn’t your cup of tea, there are several other options for staying at the Caverns. The Caverns Inn is a 48-unit motel next to the general store, bar and laundromat. The Ranch House is a three-bedroom, three-bathroom space great for large families. There is also a 48-site RV campground with water and electrical hookups.
Aside from the caverns, there are several other activities to enjoy if you are staying on property, including horseback rides, hiking trails, disc golf and more.
Peach Springs is also the gateway to the Havasupai Waterfalls. It is the closest place to stay the night before departing for a hike to the falls at the bottom of the canyon. Rafting adventures within the canyon are also available at Grand Canyon Caverns. Call 928-422-3223 for more information on these tours.
After finishing your tour at the caverns, continue the loop on Route 66 back to Interstate 40 and check out the historic town of Seligman, known for its novelty gift shops, antique cars and fun diners.
