Underground Wonderland

    Deep inside a jungle in Vietnam lies a special place. Some call it magical. Others find it terrifying. 

    For starters, it’s not easy to find. To reach its entrance, you’ll have to hike 15 miles through muddy rivers and forests. Then you must carefully climb down a rocky slope to get underground.

    Once inside, though, it’s like you’re on another planet. 

    Limestone walls stretch as high as skyscrapers. Giant stalactites—icicle-shaped structures made from minerals—hang above. At night, it is completely dark. The fish in the river have learned how to survive without sight.

    Welcome to Son Doong, the largest cave in the world. Every year, thousands of people dream of visiting it. 

    Some hope to spend the night camping inside. Others want to swim in the cave’s crystal-clear lake. Why here? It’s unlike any place on Earth. 

    First of all, Son Doong is huge. It’s about 5.6 miles long and as wide as one-and-a-half football fields. The cave is so big that a massive airplane could fit in it. Experts say the cave is anywhere from 2 million to 5 million years old.

    Most caves are entirely dark. But Son Doong has two giant openings in its roof. In these areas, light, air, and rain can get through. This allows jungles to grow and wildlife to survive.

    Scientists have even discovered new types of creatures in the cave. There are spiders, millipedes, and scorpions—all without eyes!
