This stalagmite-filled chamber is a historic and magical place.

You can also get in touch with your inner explorer by signing up for the Expedition Tour to crawl and wiggle through less-accessible cracks and crevasses below the main chamber.

Now, visitors can enjoy a safer, more comfortable tour; walk along 440 steps to discover well-lit treasures and cave formations showcasing the captivating, spiky aragonite crystals. Other remarkable formations even earned their own nicknames—look out for "Bridal Veil," "Drapery," and "Lasagna Factory."

Caverns in Southern California 

Arroyo Tapiado Mud Caves

Tucked within Anza-Borrego Desert State Park—one of the most underrated state parks—Arroyo Tapiado Mud Caves consists of 20 to 30 caves. While it has yet to be mapped out, this network of caves is confirmed to be the most extensive cave system in the world. (These intricate caves can be dangerous, though, so don't enter alone or without proper safety precautions.) Turn your excursion into an exhilarating camping trip, and go spelunking in California to trek through tiny corridors, huge halls, and open-air chambers.

Cave of Munits

Location: 24501 Vanowen Street, West Hills

Situated within El Escorpión Park, this cave has a very gripping history—according to oral accounts of the Chumash people, it was the home of a shaman who murdered the son of a politically important chief and thus met his own end.

To reach this mysterious natural landmark, hike along the El Escorpión Trail until you reach the inviting chimney cave, where you can discover its hidden cracks and surprisingly large main hall. If you're brave enough, climb up the chimney and continue on the trail to arrive at Castle Peak (an enormous rock pile) and take a well-deserved break, savoring the gorgeous vistas of the City of Angels. 

Mitchell Caverns

Nestled within the Providence Mountains State Recreation Area, the caves beckon to outdoor buffs with their lovely limestone cave formations that have withstood the test of time.

Walk along the path to visit both caves of the Mitchell Caverns—El Pakiva (The Devil’s House) and Tecopa (named after a Shoshonean chieftain)—which were discovered and operated by Jack and Ida Mitchel for 20 years. As you follow your guide from the El Pakiva Cave along the bridge over the Bottomless Pit to reach the Tecopa Cavern, you'll learn about the rich history and nature of the region.
