Depending on the conditions, you may have the option to take the Wild Cave Exit! Wear your water shoes, water sandals, or bring extra shoes to change into after your tour (no flip flops, slides, or bare feet). It is totally optional because you will get your feet completely wet, but it is a lot of fun.

This alternate ending to your tour is a special highlight for guests who would prefer to leave the cave using a path cut by the same active stream which carved the cavern. Water depths can be up to 4 inches during the rainiest season but usually is only about an inch deep.

Our Gift Shop even sells water booties so that you can enjoy the Wild Cave exit safely without getting your shoes and socks soaked.

A MUST DO IF YOU'RE IN KINGS CANYON! This cavern is unlike any I've previously visited. It's smaller and much more intimate, but it's a solid 45 minute tour that allows you to explore all of its crevices.

I loved it. Stella was our guide and she was amazing, fun, informative. Due to COVID all tours are given with just your group - which is awesome. We had a private, intimate tour and the cavern was really really cool. Especially the ending when we exited thru the creek in the Cavern.

This is an absolute must do excursion in Kings Canyon. Because of Covid my family had a private intimate tour of the cave and the photo opportunities were endless. Our tour guide was so patient with my kids and went over the history of Boyden himself and the intricate details of the cave. She took us to the end of the cave and turned off all the lights so we could experience pitch blackness in the cave. And to top it all off, we did the water exit in the end which was so cool and in my opinion, the best way to exit. Definitely the cave experience of a lifetime!

A small cave but very interesting. I love how the formations are pristine unlike other caves I have visited where they are broken or rubbed smooth from too many hands. The tour guide was very friendly and knowledgable. Tours leave on the hour. It takes a bit to walk up a very steep path of about 800 paces. Easy to find right off the highway in King's Canyon

Frequently Asked Questions

Q Is the cavern open year round?

No. Highway 180, the road to access the cavern, is closed every winter. The road is generally open between mid-November and late April, but exact dates can vary.

Q What should I bring on my tour?

You will need to bring yourself, a face covering/mask, hand sanitizer, your camera (photos are allowed and encouraged!), and a small bottle of water if needed. It is 55°F (~12.5°C) year-round inside the cave, so you might want to bring a jacket. Wear shoes that you would wear hiking. Depending on the season and weather conditions, you may have the option to get your feet wet by walking in our natural creek bed. We recommend having a change of shoes, or hiking/water sandals (closed toe recommended). No Flip Flops!

What you cannot bring:
Tripods, monopods, walking sticks

Backpacks (including baby carrier backpacks)

Food or drink, gum, candy, etc.

Strollers or other wheeled items (the cavern is not wheelchair accessible)

We recommend leaving these items in your vehicle, but if you forget and have them at the entrance, we have a small box in which you can leave them.

Q How strenuous is the tour?

The walk up to the cavern is generally the most difficult part. It is a short but very steep walk that takes most people about 5 minutes. Once inside the cave, you will need to duck, stoop, turn sideways, walk on loose rocks, walk up and down stairs and slopes, and navigate slippery areas.

At this time all guests and guides are required to wear masks/face coverings inside the cavern and gift shop. We discourage guests with pre-existing conditions, or high risk factors from taking the tour. The cavern tour has some tight areas and can be an uncomfortable environment for some people. Wearing a mask may exacerbate any breathing conditions and may make the tour more difficult for some people.

Q Do I need a flashlight?

On the regular walking tour, the cavern will be lit for you, but you are welcome to bring a flashlight to peer into corners and crevices! Please avoid shining the flashlight into others’ eyes (and instruct your kids to keep it pointed down).

Q How long is the tour?

Tours last 45-60 minutes round trip. Your tour will depart at your tour time, and the walk up to the cave takes about 5 minutes. We ask that visitors arrive 15-30 minutes before their tour. So, if you plan to take a 12 pm tour, arrive by 11:45. At 12 pm, we will send all ticket holders up the path. At about 12:10, your guide will arrive to cover the safety briefing before leading you into the cave. The tour goes back about 750 feet into the cave. You can expect to be reemerging into daylight at about 1 pm. You can walk back down the path at your leisure (it’s a beautiful view of the canyon!).

Q What is the cancellation policy?

If you need to cancel or reschedule your tour, contact us by email as soon as possible! We will always try to work with you to come to a resolution.

For cancellations made by you: Any cancellation made at least 72 hours in advance is fully refunded. Cancellations between 72 hours and the midnight prior to your tour are refunded minus a fee of 18% or rescheduled at no cost to you to any available date and time. Same day cancellations are not refunded, but we still encourage you to contact us ASAP!

For cancellations made by us: We hate to cancel tours, but unexpected things can happen! If we have to cancel your tour for any reason (natural disaster, government closure due to pandemic, staffing issue), we will automatically refund you 100%. While we’d love for you to rebook with us if you can, we don’t believe in-store credit for our guests; as for many of you, the trip here is once or twice in a lifetime. So we’d rather not give people the extra step of having to cash in-store credit for a full refund. If we cancel a tour, we will contact you by email as soon as we can.

Q Can I use flash photography?

Yes! As long as there are no bats present, you can use flash photography. Your guide will let you know if there are any restrictions in place. We also offer private extended tours, which are perfect for people who want to take their time to get the perfect shot, set up external flash or other lights, or use a tripod/monopod.

Q Are there bats in the cave?

Sometimes! Bats don’t frequent our cave very often. However, there are many other caves in the area that bats use. We occasionally will have bats – if we do, your guide will let you know not to use your flash, and we will pass through that room quickly and quietly. Don’t worry; the bats won’t bother you!

Q What age is appropriate for the cave tour?

We have had babies up to octogenarians on our tours. The walk up to the cave is very steep, so it can be strenuous for children and the elderly. However, we can let you start walking up the path early so that you can take your time! Babies can be worn in carriers only if they are worn in front. Some babies love the cave – but some have not and have left the tour early. You’re the best judge of whether or not you or someone in your group can take the tour. If you’re not able to complete the tour, just let the guide know you need to exit early, and they will make sure that you get to the gate. Then talk to us in the gift shop about a refund.

Q Can I buy snacks or drinks at the gift shop? What else do you sell?

Yes! We sell water, soda, and other beverages in the gift shop. You can also buy chips, candy, granola bars, and other snacks. If you want a hot meal, your closest option is in Cedar Grove, 10 miles away, or Grant Grove, 19 miles away. We also sell souvenirs like shirts, hats, mugs, shot glasses, and magnets. Check out our cool collection of rocks and minerals for sale! We even have unopened Geodes that you can choose and crack on site. Geodes are a special kind of rock that, when cracked or sawed open, reveals beautiful crystals!

If there is something you wanted that we didn’t have, let us know!

Q Can I have a picnic?

Only if you promise to enjoy it! We might be biased, but we think our picnic areas is one of the best places to have a meal or take a rest before or after your tour. You’ll have a fantastic view of the canyon and river. Just a warning, though, we are next to the Windy Cliffs, which live up to their name! So please be careful with napkins and small items that may blow away to avoid littering our beautiful canyon.

Q Are there restrooms?

We have three primitive pit toilets in our parking area. There is no plumbing/running water at Boyden Cavern.

Q Can I still take a tour if it is raining?

Yes! One of the great things about the cave is its constant temperature and protection from the elements! If it is raining during your trip, do take your time driving and watch for falling rocks in the road. It rarely rains during the summer season, but if it does, we’d ask you to also take extra care on the trail to the cave.

Q When did the cave reopen?

The cavern and gift shop was closed from August 2015 to May 2019 due to the Rough Fire of 2015. A new company has taken over operations as of 2019, and we are excited to be offering tours again. We reopened on May 15, 2019. We hope to see you in the cave!

Q I am interested in working at Boyden Cavern, how do I get more information?

You can get more information by emailing us at We strive to hire people who are enthusiastic and can provide excellent guest service!! Cave knowledge is not required. We can teach you all you need to know, and most guides end up learning on their off time, too; caves are just that fascinating!
