Reventón del Rio Mundo, Natural waterfall in Sierra del Segura, Spain.
Reventón del Rio Mundo is a waterfall in the Sierra del Segura that emerges from a cave opening and descends in a series of cascades. The water collects in natural pools as it flows down the mountainside before continuing into the valley below.
The waterfall developed from an underground drainage system that accumulated water over millennia before forcing through the cave opening in the mountainside. This formation resulted from geological processes that shaped the cave network over countless ages.
Local communities maintain traditional practices related to the waterfall, incorporating the natural water system into their agricultural and social patterns throughout generations.
Access is best done on foot along a marked trail that runs through the riverbed and past the cave opening. Sturdy shoes are essential, and care is needed on wet rocks since the path can become slippery.
The water does not emerge from the surface but flows out through a cave opening where it comes from underground rivers running through the entire mountain mass. This hidden origin makes it a rare example of how underground water systems can carve through stone over time.
