When taking a break from reality and the hectic life in the city, aside from the classic beach vacay, most of us go to a forest, in the mountains, or a desert. But how many of us have spent time in the undergrounds, visiting the depths of nature?

Not many people have had the chance to explore a cave and see stalactites and stalagmites or the mysterious creatures that live in a world without light. And, that’s too bad because deep down there realms of darkness and wonders await.

Are you ready for a journey beneath the earth?
