Marengo Cave
Marengo, IN · Indiana Cave Country
Two schoolchildren stumbled into Marengo Cave on a September afternoon in 1883, and tours have run almost without pause ever since, which makes this one of the oldest show caves in the country. The reason it became a National Natural Landmark is the sheer density of the decoration: the Crystal Palace and Queen's Palace chambers are packed wall to wall with stalactites, soda straws, and honey-colored flowstone draperies, earning it a reputation as the most heavily ornamented cavern in the region. Two walking tours split the difference, the quick Crystal Palace loop through the showpiece rooms and the longer Dripstone Trail past totem-pole formations and the cave's underground stream level, both held at a steady 52 degrees year round.
