09 – Kuna Cave

Kuna Caves, located just south of Kuna, Idaho, are a fascinating example of lava tube formations resulting from ancient volcanic activity. The main cavern is accessible via a caged ladder descending approximately 50 feet (15 meters) into the earth. Extending about a quarter mile north and roughly 1,000 feet (300 meters) south from the entrance, the cave maintains a comfortable year-round temperature of around 56°F (13°C), making it an inviting spot for exploration.​Wikipedia

While the cave has faced challenges such as graffiti and littering, local efforts are underway to preserve and enhance this natural wonder. In 2021, the Bureau of Land Management proposed the “Kuna Cave Recreation Site Improvement Project,” aiming to improve public facilities by adding a road leading to the caves, a parking lot, an improved ladder, and a new grate to deter vandalism. Visitors are encouraged to respect the site by following Leave No Trace principles, ensuring that the caves remain a pristine and enjoyable destination for all.​

Easy enough road in just took it slow given the bikes we were on. The cattle guard has a nice little step off but no drama. Went down in the cave and went back until the point were you would need to actually crawl, didn’t want to mess up the fresh digs so turned around.

Smells like feedlot out here. I didn’t go down in because there were a bunch of kids there going up and down the ladder. Pretty easy ride. Compacted dirt and ruts the last few hundred yards is all.

Glad I could be of service Chilly! I included a picture of Chilly “At least it’s not windy down here” Philly from the floor of the cave. Remember to take a flashlight and explore when you get down there. This is a cool spot. Another one of those places that I’ve been by a hundred times and never stopped to check it out. Thanks for putting this on the list of places this year!

We came in from the north. A little nasty water filled in the road here and there we had to dodge around, but the road wasn’t terrible aside from the potholes.

Spent a short time in the cave. Came back out (it was a cold and windy morning) and my little Princess decided she wouldn’t start because, well, it was too cold. Fortunately FW190Pilot had a strap and came to the rescue. He was able to tow me out to the main road and pull started the delicate girl. Thanks FW190Pilot!

First time here not a bad road but very rutty. A smelly ride though past all the ranches.

Mistook Kuna cave for Higby’s cave that I slept in as a youth. First visit for me.

There are some ruts, and you might be careful if it’s wet outside. Otherwise not too bad. Easily doable on a big bike.

I highly recommend exploring the cave if you have time. Brittan and I climbed to the bottom but didn’t have any lights to go further.

I suggest not attempting this if it is muddy. Deep ruts are manageable otherwise.

It’s been a few years since I’ve been out to this cave. The road is short and a lot more rutted then I remember.

This is a tricky find. My phone tried to take me through an operational cattle ranch. Rancher was super nice, and directed me to it. Traveling west on Kuna Cave Road, *JUST PAST* the second house on the left is a gravel road, take that over the cattle guard, and what you are looking for is just off to the left. This one was tricky!

Needed GPS to find the location as there are no signs posted that I could locate. The main dirt road was in good shape, but the closer you get to the site the road is full of deep ruts and other debris.

Went here on the way to the picnic. Never been before, cool little spot out in a field.
Didn’t have my bandana yet since it was on the way. Hopefully I get credit😁
