The Remarkable History Of Colossal Cave In Arizona Spans From Ancient Times To Modern Day

There are many cavern systems crisscrossing under the vast Arizona desert landscape, but today, we're focusing on one in particular: Colossal Cave. This ancient labyrinth began forming 80 million years ago, serving as a home for indigenous peoples as early as 900 A.D. It's open to the public for tours, and this is an experience you don't want to skip.

You can find pictures of Colossal Cave dating to the 1920s, but not even an entire century can tell the full story of this ancient place.

Water erosion began forming the cavern system about 80 million years ago, and its first inhabitants -- the prehistoric Hohokam culture -- used the complex underground labyrinth as temporary shelter as early as 900 A.D.

Today, Colossal Cave is on the National Register of Historic Places, offering visitors a glimpse into its archaic history with geology that has hardly changed over the millennia.

Several different tours offer something for everyone, whether you want a bonafide spelunking experience or leisurely stroll through the vast underground chambers.

Most families prefer the classic tour, which takes about 50 minutes.

You'll descend six stories deep, marveling at incredible rock formations while a friendly, knowledgeable guide recounts stories about the cave's history and urban legends like ghosts and robbers. This tour costs $18 for adults, $9 for children 5-12, and kids under five get in for free.

Those looking to take the adventure up a notch should choose the Ladder Tour.

This 1.5-hour excursion turns you into a real cave explorer, leading through tight passageways and other hidden areas of the cave restricted from public access since the 1950s. You'll also learn about more unique geological formations not visible on the regular tour -- and perhaps get acquainted with a bat or spider along the way! You'll need to make reservations ahead of time, and the tour costs $35 a person.

Another option is the Wild Cave Tour, a 3.5-hour, down-and-dirty escapade that follows in the footsteps of early 19th century explorers and outlaws to the deepest, darkest corners of the cave.

Only those aged 16+ can participate, and rates are $85 or $125 depending on which difficulty level you choose. There's also a special kid-friendly tour, and special groups are welcome as well.

The fun doesn't even come close to stopping once you're back above-ground.

There's gem mining, a petting zoo, five miles of scenic trails, camping, and picnicking. And can we just take a second to admire this view?
