Crystal Cave Is Finally Reopening This May At Sequoia National Park

Crystal Cave, Sequoia and Kings Canyon National Parks

While Sequoia’s massive trees grab all the headlines above ground, something just as cool has been hiding underneath. Crystal Cave, a maze of marble tunnels and crystal formations, is ready to welcome visitors again after three years.

Here’s what you need to know.

Four Years in the Making

This place has been locked up since 2021 when the KNP Complex wildfire tore through. 

The road, trail, all the visitor spots. Everything got hammered, first by fire, then by the biblical winter storms of 2023. 

The fire left a graveyard of dead trees near the cave entrance, death traps waiting to fall, while the rains that followed ripped apart the only road in. While the cave slept, die-hards had to settle for virtual tours shot in better days. 

Now, after years of work, the paths and visitor areas are finally patched up and ready for your muddy boots.

Mark Your Calendar for May 23rd

The gates to this underground realm swing open May 23rd and stay that way until September 7th. Tours run from 9 to 3 daily. 

Get there 15-20 minutes early or you’re not getting in. 

The drive up is a 45-minute crawl on roads that twist like intestines. 

Skip the summer entrance lines by grabbing your pass on the NPS app beforehand.

Tickets went on sale end of March, and the prime summer slots are vanishing faster than free drinks at a press event.

A Natural Wonder Worth the Wait

Inside waits a half-mile loop lined with rock formations that’ll make your jaw drop Stalactites hanging like stone icicles from the ceiling, flowstone that looks like frozen waterfalls, mineral curtains draped like some alien theater. 

First spotted back in 1918, they’ve since paved the walkways and added solar lights, concessions to safety that somehow don’t kill the magic. 

You’ll see polished marble along Yucca Creek, hollow stone straws thinner than your pinky, and tiny dams built by nothing but water and time. 

One of the State’s Largest Cave Systems

Crystal Cave is the second-largest of 275 known caves in these parks and the fourth-biggest in all of California, with over three miles of mapped tunnels. 

Most of the park’s 865,952 acres are wild backcountry, caves included. 

No lights, no paths, no handrails for the timid. 

These parks hoard half of California’s mile-long caves, including the longest in the state, a subterranean empire most visitors never know exists. 

Guided Tours Only

The crystal formations here break if you breathe on them wrong, so you’re only getting in with a 50-minute guided tour where you can learn about the cave’s geology, ecology, and history.

There’s a 4-6 hour Wild Cave option for anyone over 16 – belly-crawling through tight spots, climbing past drops that would end you, seeing the formations most tourists never will. 

The Family Cave Tour (10 and up) gives you helmets and lights to see The Well.

Be Ready for a Workout

This isn’t some flat walk through a gift shop. The trail has stairs equivalent to a 20-story building. 

At least the cave stays a crisp 50°F year-round – nature’s air conditioning when the surface feels like a hot kitchen. 

The whole trek runs 1.5 miles, with a brutal 320-foot climb packed into just a half-mile on the return.

Block out 3-3.5 hours for the whole experience. Drive time, hiking, the tour itself, and waiting around for stragglers. 

Book Your Tickets Now

Tours run every half hour, priced at a reasonable $20 for adults and $10 for kids under 10, plus the usual fees they tack on for everything these days. 

May’s practically sold out, but June through August still has slots for the procrastinators. 

Book at least a month ahead or kiss the summer dates goodbye. 

And don’t expect to charm your way in at the entrance. 

It’s online tickets only at sequoiaparksconservancy.org, not a cash dollar accepted. 

All food and anything scented goes in the bear boxes at the parking lot.
