3. Waitomo Glowworm Cave
As also mentioned in my Most Alien looking places in the world video, This one will definitely leave you spellbound due to the millions of glowworms that have populated the cave. Added to this is another amazing fact- the cave is a part of a chain of caves, including Ruakuri Cave and Aranui Cave, that is called the Waitomo Caves. This is what makes it an attractive spot for the tourists and locals alike. One can take a small trip inside the cave in a small wooden boat. The Waitomo Caves also have large amounts of limestone, which is said to have formed around thirty million years back, due to geological changes.
2. The Cave of Crystals
Located about a 1000 ft. below the surface of Chihuahua, Mexico. The main chamber contains large amounts of giant selenite crystals and the largest found weighs over 50 tons. The temperature inside goes up to 136 degrees Celcius with approximately 95 percent humidity. These factors prevent scientists and other people from exploring the cave. Even with proper protection costumes and other safety measurements, a person can last for only about ten minutes inside stunning cave of Crystals.
1. Hang Son Doong, Vietnam:
Also known as the ‘mountain river cave’, Hang Son Doong is said to be one of the largest cave systems in the world. What makes it all the more interesting is that it has its own river, jungle and climate. For a long time, the locals had been reluctant of going nea r the cave area, because of the scary noises produced by the wind and fast-flowing water. Although the cave was discovered in the year 1991, it was not until 2009 that it became internationally known through a research conducted by a group of scientists. Although i really want you to go there yourself, National Geographic has done an awesome 360 photo tour, so you can check it out on your computer before you go. I’ll leave a link to all the videos included in this video and the photo tour down in the description below.
