Hiking Crystal Cave Trail
Crystal Cave is a short and popular tour within Sequoia National Park. The tour features the park’s only commercial cave which is part of a larger cave system. Tours range anywhere from forty-five minutes to six hours as a guide takes people through the intricate cave system and explains the cave details and history. If you’re at all interested in booking a tour to see the inside of Crystal Cave, check out the park’s website. Tours range anywhere from forty-five minutes to six hours. I recommend going with the forty-five minute tour. It will tell you all you need to know.
Crystal Cave Fun Facts and History
Crystal Cave is what is known as a karst – a type of landscape layered with soluble rocks like limestone. The limestone can give way to sinkholes, sinking streams, underground drainage systems, and in this case, a cave. Between Sequoia and Kings Canyon, the two parks contain over two hundred and seventy-five cafes. In fact, in these two parks lay half of California’s caves and the longest cave in the state. Within the caves are delicate ecosystems full of unique animals, Pleistocene era fossils, and rare minerals.
The porous landscape that makes up Crystal Cave allows snowmelt and other water sources to flow within the cave. The cave’s water source helps to keep temperatures cool – especially during the summer. Crystal Cave features some exciting topography including speleothems (long curtains of eroded stone), stalagmites, pools of water, and angular curving growth forms.
On an interesting note, the first documented knowledge of Crystal Cave was on April 28th, 1918 by Alex Medley and Cassius Webster. Medley and Webster were two trail workers who were doing a little exploring on one of their days off. The two reported their finding to their supervisor, Walter Fry. Fry originally came to the area as a logger. However in the span of about a week Fry had immense guilt after realizing the significance of chopping down giant sequoias. Fry went on to become superintendent of Sequoia National Park and worked to create the National Park Service.
Some things to keep in mind when touring Crystal Cave:
Flash photography is not allowed. Prohibited items include purses, bags, backpacks, baby carriers, hiking sticks, tripods, monopods, food or flavored beverages (water is okay), or pets (service animals are okay).
Most importantly, any articles of clothing, shoes, or any gear that have ever been in any cave in any part of the world since 2005 are not allowed. This is due to white-nose syndrome. White-nose syndrome is a debilitating disease that has been killing bats who make their home in caves. The disease is spread by fungus and can be carried into caves on gear, clothing, and shoes. White-nose Syndrome is originally from Europe but has spread to North America since around mid-2000’s.
The fungus grows on the skin of bats while they hibernate during the winter. The skin becomes so damaged that their temperature increases and causes the bats to wake up. Their awakened state causes the bats to use energy that needs to be saved to last through the winter. In many instances bats die from starvation. In other instances when bats are awoken they think it’s time to go look for food. The bats leave the cave during winter and can die from hypothermia. White-nose syndrome is a sad but constant reminder that we as people need to take caution to not disturb natural ecosystems.
On A Personal Note:
Of all things to do in Sequoia National Park, a cave tour is not something I expected to do. I personally did the forty-five minute cave tour and thought that it was the perfect amount of time. The park rangers were incredibly informative about the cave history, cave species, and other fun facts. I highly recommend Crystal Cave as something different to do in Sequoia National Park.

Crystal Cave Trail Conditions:
The trail does give a couple views of nearby hills/canyons but this trail isn’t really known for it’s open panoramic views. There are also a few hazards along the trail: poison oak does line certain portions of the trail and rattlesnakes are common in this area as well. Staff for the Crystal Cave tour does a very well job of describing what poison oak looks like and what to do if a rattlesnake is encountered. For the most part, poison oak is maintained and kept away from the trail.
Once to the bottom of the trail there is a small waterfall near the cave entrance that makes for a crowded yet pleasant photo opportunity. At the cave entrance the guide will gather the group and lead everyone through the cave. Once inside the cave the path gives way from paved to marble, limestone, and granite surfaces. The conditions inside the cave are cool, dark, and damp. When I visited the park, temperatures were in the high 80’s and cave temperatures were probably in the high 50’s. For me the cool temperatures were a nice relief to the heat outside.
Despite the dark conditions, the majority of Crystal Cave is lit with dim lighting installed by the National Park Service. The tour guide is well informed and throughout the tour shares standout features inside the cave, how certain cave features are made, and historical facts about the cave.
