Arizona is filled with natural wonders just waiting to be explored. From natural bridges to magical waterfalls, the Grand Canyon State has it all, and exploring the following cave is one of the most unique hikes you'll ever take - we promise. Check it out:
Arizona's only known lava river cave is a rare natural wonder.
At just under one mile long, it's entirely underground and was created by a volcanic eruption more than 700 million years ago.
As a red-hot river of lava flowed during the eruption, the edges of the tube hardened, while the hottest lava continued to flow and eventually emptied out of the tube.
What remains today is a lava river cave, with ridges on the floor and lava spikes "dripping" from the ceiling. Exploring the lava river cave is surreal and, at times, a bit dicey.
The entrance to the cave is a slight opening that drops sharply by way of a rocky incline until it levels off. The temperature in the cave remains a chilling 40 degrees Fahrenheit year-round (sometimes less), making ice underfoot a distinct reality in some places.
If you want to explore Arizona's only lava river cave, be sure to bring plenty of light! The light on your cell phone will not be enough.
Also, wear appropriate boots: the terrain can be unsteady. At some points along the way, the height of the cave can be as high as 30 feet, but at other points, it's as little as three feet. Watch your head for those overhead dangling lava drips.
The lava river cave is located approximately 15 miles outside of Flagstaff, deep in the Coconino National Forest.
Wear warm clothes and bring extra light sources. Many reviews from hikers recommend that this adventure is not appropriate for really young children. If they are unable to walk the distance, or maneuver through the difficult terrain inside the cave, then this could put you both at risk in the event that you end up carrying the little one.
Learn more about Arizona's Lava Tube Cave at this link on the website of the US Forest Service. The cave is open year-round and entrance is free - however, make sure to check the website for current closures while planning your trip, as sometimes inclement weather or other things may cause the Forest Service to close the cave to visitors. The road leading to the cave can be unexpectedly closed due to winter weather or wet conditions, as well, so it's important to double-check. You'll find the entrance to the cave at this Google map location.
