Located in a collapsed lava tube, Bandera's ice cave never rises above 31º Fahrenheit. You feel the temperature change dramatically as you descend the stairs. The igneous (volcanic) stone insulates like the ultimate Yeti cooler. The ice has been accumulating for more than 3,400 years (based on core samples tested). It is more than 20-feet deep and regenerates as new rain and snow melt seep into the cave.
