Kuna Caves are lava tubes found south of Kuna, Idaho. There is currently one publicly known entrance to the cave, an opening in the ground with a caged ladder leading down into the cave.
The caves are about 50 feet (15 m) deep and run about a quarter mile north and around 1,000 feet (300 m) south from the entrance. The southern portion of the cave requires you to crawl through a trench dug out of the clay floor of the cave leading to a small space approximately 4 feet (1.2 m) long by 3 feet (0.91 m) wide by 3 feet (0.91 m) high in which you can turn around to return to the main cavern.
It is important to note that the caves are not monitored. While it is interesting to see, young kids may not be well suited for this venture. The caves are riddled with graffiti and litter.
