The Grand Canyon State is filled with hidden gems, you just have to know where to look. One gem we've found is an underground cave in Arizona that's 600-feet long. It's a perfect place for adventurers to explore. 

The Coronado Cave is a massive cavern found near Hereford, Arizona. According to the National Park Service, it's only one of a few undeveloped caves in Southern Arizona that are open to the public. There's also no permit needed to hike there.

It's open year-round between sunrise and sunset. The trail to the cave is steep and approximately 1-mile roundtrip from the trailhead. It's rated as moderate due to the 500-foot elevation change, so plan accordingly.

There's only one way into the cave and once inside, its pitch black. Before you go on your underground adventure it's important to bring some essentials such as at least two sources of light, extra batteries, water, gloves, and a helmet.

You'll find the trailhead to the cave about .25-miles west of the visitor center on East Montezuma Canyon Road. Once inside, you'll be amazed at what you find. 

There are many rooms within the cave and some of them even have rock formations. Since oil from the skin can prevent new formations from forming, it's important to try and not touch the walls and rocks you may encounter.

The cave may be home to bats, so to ensure your safety and theirs, you should refrain from playing music or talking loudly since they are sensitive to noise. 

If you want to have a picnic or snack after your adventure there are some picnic tables and restrooms available near the visitor center and picnic area. 

Exploring underground caves are some of our favorite things to do. If you want to go on an underground hike that takes you through a lava tube, you can. It's the perfect outdoor adventure with friends.
