Mammoth Cave is one of the largest lava tubes in Utah, with over 2,200 feet of passage and four chambers on the Markagunt Plateau in Dixie National Forest. It was formed by cooling lava roughly 2,000 years ago and sits at about 8,050 feet elevation. The cave stays cool year-round and has five entrances with multiple interconnected tubes. It remains undeveloped—no lights or paved walkways—so self-guided exploration requires a headlamp and sturdy shoes. Difficulty is moderate, with some crawling and tight passages.
