The Kuna Caves are underground lava tubes located in Kuna, Idaho. These lava tubes were formed when lava flowed freely underground and were left hollow when the volcano became extinct.

The Kuna Caves have one entrance. Spelunkers climb down a caged ladder at the entrance of the cave to descend into the lava tube. The decent is about 50 feet. The ladder and cave system are unmaintained so visitors should take safety precautions when exploring the Kuna Caves.

Once at the bottom of the cave the tunnel extends about a quarter mile to the north and a quarter mile to the south. Both directions have places where explorers can stand and walk and tighter places where explorers must crawl. The cave is a cool 56 degrees year round. Spelunkers should bring their own flashlights or lanterns. 

This area is called the Kuna Caves because the single remaining cave used to be a part of a much larger system that is now inaccessible. The remaining cave system has graffiti and litter along the cave. Parking is available on the dirt road at the cave entrance. 

Kuna Cave is an exciting lava tube to explore and enjoy climbing and crawling around in. Visitors and locals in Idaho can enjoy this unique adventure in the dusty desert.

Lava Tube - Cave. These are formed when fluid, molten lava flows out of the ground, it behaves like a stream of water working its way downhill. But soon the "stream" surface cools and hardens. This crust then insulated the molten lava inside, enabling it to keep flowing. The molten lava inside the crust eventually flows out leaving the crust as the walls of a lava tube or "cave."

Eureka Cave is a lava tube. In other words, this was previously a tunnel for lava flows. There's a large hole to get into the cave. While climbing equipment is helpful, most relatively fit individual are able to make the descent without much difficulty. Sadly, like most of these caves, there has been a considerable amount of vandalizing and littering. Please pack out what you pack in and leave the place better than you found it.

Owl Cave is located out by the Dead Horse Cave and Spider  Caves (Mckinley Butte Lava Tubes). Owl Cave is about 100 yards from Spider Cave and is also closed Seasonally from Nov-May but ocassionally open longer This is a massive lava tube as you enter you will climb up in to a gate you enter through the gate when open and goes back a good ways great cave to explore

Located near Mountain Home, this is unlike most caves in the area. It's not a lava tube but a fissure. A crack that opened when the lava cooled. The entrance is closest to the corner. For the most part there are arrows pointing which way to go. The entrances and exits in some rooms took us a long time to find so be prepared for a couple of hours underground. Just before the cave decends to the bottom of the lava flow there is a good 20 ft vertical drop. After the bottom the caverns slowly begin th regain altitude, eventually leading to the exit, abut 100 yards north of the entrance.
