This memorable natural wonder is a small complex of three natural features a few miles west of Cabrera (admission 100 pesos). It has recently evolved and has been made more like a park. A zip line (costs about $5) has been installed and one can jump off a cliff into one of the deep swimming holes. Most times there is a lifeguard below on a paddleboard.
There is a lagoon with cold, clean water that you can swim in. Then walk over to explore a nearby natural cave (bring your own flashlight if you remember). Then, across the way take stairs down into a spring that flows inside a cave; adventurous types swim into the mouth.
A restaurant now serves a small menu and cold drinks and there are toilets and even a shower.
