In the rainy season, you may not be able to cross the tunnel without getting your feet wet. But it is impressive to find this at the beginning.

One of the most beautiful caves I have ever seen. First because of the location, second because of the small challenge of not getting lost to get there, and thirdly because it is super cool: a huge mouth and easy to travel (with a flashlight) a good stretch. Absolutely recommended.

Beautiful area, it is recommended or almost mandatory to carry a flashlight, since although the cave is short and does not involve much difficulty, it is always good to see where you put your feet

Very close to the beginning of the route, it is a surprising area.
