Cave layout

There are two entrances to the cave, both at the end of Spring Cave Trail. Most visitors prefer the nearest entrance, an over-two-meter-high passageway. From there one descends through several rooms leading to a permanent ladder, followed by more rooms leading to the river. It is the largest river inside a cave in Colorado. The level of the river rises and falls throughout the year, and can even rise to the level of the cave entrance on rare occasions. There are several series of rooms above and past the river, a few of which lead to an underground lake. Past the lake lie several sumps which must be passed through diving. The full extent of the cavern and underground waterways in it is still not completely known.
