Explore Crystal Cave as it reopens at Sequoia National Park for this season
After a four-year closure due to natural disasters, Crystal Cave in Sequoia National Park reopened to the public this weekend in time for Memorial Day, the unofficial start of the summer.
Crystal Cave is located near the Giant Forest area and has been one of the most popular visitor destinations in the park since it opened for public tours in 1940.
Since the announcement earlier this year that the cave was reopening for the 2025 season, “the response from the public has been overwhelming,” said Nicole Stivers, marketing and communications director for Sequoia Parks Conservancy.
“It’s a beautiful reminder of how people value these experiences in our national parks,” Stivers said.
For people in the Central Valley, Crystal Cave has been just more than a tour or a rite of passage.
“It’s a portal to something extraordinary,” Stiver said. “A hidden world beneath the forest floor with cool air, sparkling formations and fairy pools.”
Guided tours tickets for the first several weeks of the 2025 season — which runs from May 23 to Sept. 7 — are sold out, Stivers said. She said one-third of the entire season has been sold as of May 22. Tours are from 9 a.m. to 3 p.m. and can be booked online only. Tickets will not be available for purchase onsite.
Before its closure due to wildfires, floods and other nature incidents, an average of 51,000 people visited the cave each summer, according to the conservancy.
Clay Jordan, Sequoia and Kings Canyon National Parks superintendent, said the reopening of Crystal Cave is not only a milestone but a big step toward recovering from “the most unprecedented national disasters in the park’s 135 years history.”
For example, the road and infrastructure leading to Crystal Cave were greatly impacted by the KNP Complex wildfire in 2021, and again during the severe winter storms in 2022 and 2023, which created unsafe conditions for visitors.
The cave closed in 2020 due to COVID and was affected by the Castle Fire that year, as well. While the cave reopened for the 2021 season with limitations due to COVID mitigations, the season was cut short because the KNP Complex fire left “a much more catastrophic impact to the park’s infrastructure,” Jordan said.
According to Jordan several projects over the last three to four years helped restore access, including power line replacement, road stabilization, and clearing hazardous trees along Crystal Cave Road. About 4,800 hazard trees have been removed along the route to the cave.
“Although we are still under construction, we are happy that we could get this open at the earlier possible time in order to restore access for people to be able to experience (Crystal Cave,” Jordan said.
As crew continue to remove felled hazard trees along the roadway, visitors to the cave can expect traffic delays throughout the 2025 season. Road construction and other projects are expected to continue after the season ends.
The reopening of the cave is “a celebration of resilience and the deep love so many people have for this National Park and this place,” Stiver said.
“This moment in time, has been a labor of love to get here,” said Savannah Boiano, executive director of the Sequoia Parks Conservancy.
Boiano called the reopening a “historic moment” that represents the next chapter in the legacy of the national park.
“Crystal Cave is not only a source of inspiration to visitors. It’s a place where they become active participants in conservation and stewardship,” said Boiano. “We’re not just restoring access today, we’re ensuring the sustainability of this ecosystem for future generations.”
According to Boiano, more than 450 visitors a day will be able to experience the cave this season.
The cave is operated by Sequoia Parks Conservancy, the nonprofit partner of Sequoia and Kings Canyon national parks that manages the park stores inside the visitor centers. The conservancy has served as the tour operator for Crystal Cave since 1982.
