Declared a National Natural Landmark in 1976, Black Chasm Cavern is abound with helictites, which are formations that seem to defy the laws of gravity with how they grow every which way, a formation that is found in only 5% of caves in the world. You can tour the caverns, as well as take a tour of the Miners Trail, dating back to the California Gold Rush during the 19th century.
Ape Caves — South Cascades — Longview, Washington
Ape Caves in Washington is for those who want to explore on their own — there are no tours; they are simply part of a hike. The caves are actually lava tubes formed by an eruption of Mt. St. Helen’s 2,000 years ago, and are located within Mount St. Helens National Volcanic Monument and Gifford Pinchot National Forest. You can choose to hike the lower cave, which is less strenuous than the upper cave, and gives you a chance to see a geographical anomaly, the “meatball,” which, according to a local newspaper, is a “block of cooled lava which fell from the lava tube ceiling while lava was still flowing through the cave.” The upper cave requires an eight foot wall climb, narrow passageways and climbing over rock formations.
Luray Caverns — Luray, Virginia
The largest caverns in the Eastern United States, the Luray Caverns have been dubbed “Geologies Hall of Fame” according to the official website. A registered natural landmark, you’ll be dazzled by sights like the Great Stalacpipe Organ, the world’s largest musical instrument, which, according to the official website, “literally makes stalactites sing by gently tapping them throughout three acres of the caverns.” It is played live during each tour, so you should get a chance to hear it if you go. You’ll also be amazed by the mirror image of the stalactites given by Dream Lake, and Titania’s Veil, which showcases calcite in its purest form.
Moaning Caverns — Vallecito, California
Getting its name from the “moaning” sounds that the caves sometimes would emit (due to low water levels in holes in the rock), Moaning Caverns houses the largest single cave chamber in California. Although rare now, the moaning sounds were thought to have lured gold miners to the caverns in the 19th century, while MiWok Indian lore said it was a stone giant who lured people into the caves, and ultimately to their deaths. Which might explain why several human remains have been found in the cavern, some dating back as far as 12,000 years ago. Their most popular tour is the Spiral Tour, which leads you down a hundred-foot high 7-spiral staircase, and is for visitors of any age. For the more adventurous (and those older than 12 years old), there is the Expedition Tour, which requires hard hats, crawling and lots of wriggling!

Boat tours on glass-bottomed boats will take you to the lost sea after a tour of the caverns, and there for groups of twelve or more, there is the option to experience the wild cave tour, where you not only get a more close up look of the cave, but you can spend the night!
