This time I went about 100-200 meters, until I reached some stairs with something resembling railings. I didn't go any further because I was alone, without signal, and I was afraid of going any further.

A great cave for a stroll. This time it was harder for me because it was filled with water.

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.
