The Location of the Worlds Largest Cave

Quck answer

The world’s largest cave is called Hang Son Doong and it is located in the Phong Nha-Ke Bang National Park in Vietnam. Hang Son Doong was discovered in 1991 and is over 5.5 miles long with sections reaching heights of 650 feet and widths of 490 feet. It is estimated to be around 3 million years old and is known for its unique geological formations and underground river. The cave is a popular destination for adventurous travelers and offers guided tours for those who want to explore its magnificent beauty.


Are you an avid explorer? Our planet, Earth, is filled with numerous examples of natural beauty and marvels that are impossible to witness in just one lifetime.

From majestic waterfalls and powerful volcanoes to towering mountains and vast rainforests teaming with diverse forms of life, there is an abundance of places to discover. However, our focus often remains on the surface, neglecting the unexplored areas beneath Earth’s crust.

Have you ever ventured into a cave? If so, you are aware that a completely different world awaits below the surface of the Earth.

Scientists believe that caves have existed for millions of years, as the natural erosion processes by water take a significant amount of time to form them. Therefore, it is quite surprising that the world’s largest cave, as recognized by experts today, was only discovered in 1991!

Situated in the middle of Phong Nha-Ke Bang National Park in central Vietnam, near the border with Laos, is the Hang Son Doong cave (translated as “Mountain River Cave” in English). Its entrance was initially found in 1991 by a local farmer named Ho Khanh. However, he was unable to explore it due to the steep terrain.

Although Khanh reported his discovery to the British Caving Research Association (BCRA), he lost the location while trying to retrace his steps back to the cave entrance. It remained lost for almost two decades until he stumbled upon it again in 2008.

In 2009, Khanh successfully guided Howard and Deb Limbert from BCRA to the entrance of Hang Son Doong. They were the first explorers to venture into the cave, and their findings left the world in awe.

So, why did Hang Son Doong remain undiscovered for so long? The primary challenge was its location and difficult accessibility. To reach the cave entrance, one must trek through dense jungle and cross multiple rivers. Furthermore, accessing the entrance requires rappelling down over 260 feet of jagged stone walls.

Once inside the cave, visitors are astounded by its immense size. The entire length of the cave spans over 5.5 miles, with the main passage alone stretching over three miles long, approximately 650 feet tall, and nearly 500 feet wide.

To put this into perspective, the main passage is so vast that it could contain an entire New York City block, complete with 40-story skyscrapers. In fact, a Boeing 747 could fly through the cavern without any obstacles!

The cave features an underground river, a thriving jungle, and its own weather system that creates misty clouds near the ceiling. The jungle has formed due to dolines, which are large areas where the cave ceiling collapsed, allowing sunlight and rain to enter.

Trees and various vegetation flourish in the cave, over 600 feet below the Earth’s surface. Some trees reach heights of nearly 100 feet. The underground jungle has become a habitat for animals that are not typically found underground, including monkeys, flying foxes, and various bird species.

Hang Son Doong is also home to the largest stalagmite ever discovered, known as the “Hand of Dog” due to its shape, standing at approximately 262 feet tall.

In 2013, the Vietnamese government made Hang Son Doong accessible to the public. However, in order to protect its fragile ecosystem, only one tour company, Oxalis, is permitted to bring adventurers to the cave. Additionally, the number of people allowed to visit the cave each year is very limited.

If you’re seeking an extraordinary adventure, tours of Hang Son Doong begin at $3,000 per person. Be prepared to trek through the jungle, swim across rivers, rappel down stone mountains, and maneuver obstacles by crawling and climbing. The experience, however, is well worth it when you have the opportunity to camp inside the world’s largest cave for multiple nights!
