Boyden Cavern is a showy cave in the Giant Sequoia National Monument along the Kings Canyon Scenic Byway in Fresno County, CA. Daily tours are offered at the cavern and, on-site, there is an international gift shop and picnic tables. Many tourists unfairly compare this to the Crystal Cave, but Boyden Cavern has a beauty of its own, and the history associated with Boyden Cavern is far more interesting.

The cave is a perfect example of a solutional cave that was formed in metamorphosed limestone. It houses a vast variety of natural speleothems, including the beautiful ‘shield’ formations. It is not renowned for being a bat cave, but one can spot a few caves sleeping blissfully inside the cavern during summer. 

How Big is Boyden Cavern?

The Boyden Cavern, which is in Kings Canyon, lies beneath the King’s Gates’s huge 2000 ft marble walls. The main passageway has a length of 1000 ft, but visitors are allowed to explore 2/3rd of the length. 

History of Boyden Cavern

Boyden Cavern is a great example of Karst Cave, but it was originally outside the boundaries of NPS or the National Park System.

Putnam Boyden discovered it in the late 1800s. Boyden was the first to find and claim the cave and the first human resident of the cave. The cave had several favorable conditions, and all these convinced Boyden to live in the cave along with his friend Denver Church.

Both the men lived in the cave for many years, but Boyden contracted hypothermia and breathed his last in the cave.

Soon after, the government took control of the cave in 1893 and it was eventually made a part of the National Park System.

In the 1930s, the Civil Conservation Core built several bridges and ramps in the cave to become accessible to visitors to the park. Sadly, some of the formations got destroyed by this developmental work. The only positive from this is that those bridges and ramps are still used by visitors today.

Geological Cave Formations in Boyden Cavern

Boyden Cavern is bound to impress every visitor with its magnificent collection of stalactites, stalagmites, and other rock formations with thousands of years of geologic history attached to it. There are some popular formations, and various nicknames have been assigned to them as per their shapes, such as pancakes and the group of stalactites called Upside Down City.

If you look closely, you will find a group of stalactites that look like a collection of skyscrapers hanging from the rock. The Drapery Room is the most impressive as the stalactites resemble hanging curtain drapes. Since it is a living cave, touching any of the formations is strictly prohibited. 

Wildlife in Boyden Cavern 

We know that caves form a natural habitat for bats, but they are not really common in the Boyden Cavern. They do, however, frequent other caves in the vicinity. People have also reported seeing lots of small insects and animals that are usually found near all caves.

Is Boyden Cavern Haunted?

The cavern is open to tourists every year, and there has never been any complaint of the cavern or its immediate surroundings being haunted.  

Boyden Cavern Tours

The tours at the Boyden Cavern are fully compliant with COVID guidelines. The tours last for around 60 min (round trip), but departure timings are based on the availability in the season. The Walking Tour starts with a short but steep uphill walk along the paved trail to the cave’s entrance. The trail begins from a gift shop shack. It is a beautiful climb, and the journey is fantastic with the sound of the roaring river as the background sound. 

People tend to compare this cave with the more popular Crystal Cave, but this cavern is undoubtedly less touristy than its ‘competitor’. The main passageway is 1000 ft long, but only about 750 ft is open for public tours. You can explore the remaining 250 ft, but it would require a lot of crawling and scrambling.

If you love adventure, you can surely try them.

The visitors are led through paved paths, which are well-it and have handrails. On the way, you would be able to see a wide array of natural formations. The sheer collection of stalactites and stalagmites are bound to impress all. You cannot touch the formations as this is a living cave, and the chemicals from our bodies can make them stop growing.

There is a Bat Grotto in the cave, but it is improbable that you will spot any bats as they rarely visit this cave. 

It is one of the best caves in California to take pictures, but the truly magical moment would come when the guide turns off all lights so that the visitors can experience total darkness. It might feel a bit weird in those ten-odd seconds of complete darkness, but the experience is unforgettable.

It is a perfect way to understand how Mr. Boyden would have felt when his lantern went out! When the tour nears the end after 45 min, the guide will invite the visitors for an adventure trail that is challenging and will entail some squeezing and climbing. So, if you are okay with it, you can take this trail to make your trip memorable.
