description Kuna Caves Overview
Kuna Caves is a lava-tube cave in southern Idaho, within the volcanic landscape of the Snake River Plain. Visitors enter through a constructed opening and descend into a basalt passage formed when the surface of a lava flow hardened while molten lava continued moving beneath it. The undeveloped cave is used for informal exploration rather than guided tourism, so visitors need suitable lighting, sturdy footwear, and awareness of uneven rock and changing conditions.
