The winners for the largest caves in the world can be based on several different conceptions. If the largest caves are those with the largest chambers, then there is a clear winner. The cave with the largest chamber is the Malaysian cave Gua Nasib Bagus, located in Gunung Mulu National Park, with the chamber in question being named Sarawak Chamber. Sarawak Chamber is 2,300 feet (about 700 m) long, 1,300 feet (about 396 m) wide, and around 230 feet (about 70 m) high. The runner-up is Carlsbad Caverns, located at Carlsbad Caverns National Park in New Mexico, in which the Big Room, a natural limestone chamber, is almost 4,000 feet (about 1,219 m) long, 625 feet (190.5 m) wide, and 350 feet (about 107 m) high at the highest point.
The longest cave system is Mammoth Cave in Kentucky, it's length is 367 miles (591 kilometers).
Mammoth cave in Kentucky is big in fact the biggest cave in the world! (By total surveyed length.)
Taking "largest" to mean longest... Not easy to establish - different sources quote different lengths but the most extensive is the Flint Ridge - Mammoth Cave system, in Kentucky,with over 350 miles of surveyed passages. Caves over 100 miles long are unusual; one of this magnitude rare.This length is notof a single passage but a complex network.
The Mammoth Cave is the largest cave in the United States.
Caves are recorded by passage length totals, not area, except perhaps when analysing their local geographical context. The World's longest is the Mammoth Cave - Flint Ridge Cave system.
Not a very good question. Longest in passage length: Flint Ridge / Mammoth Cave system (USA) Largest single chamber: Sarawak Chamber (Sarawak!)
Mammoth Cave, located in Kentucky's Mammoth Cave National Park in the United States.
Actually it depends, Fern Cave is the largest cave in volume and Honeycreek is the longest. Hope this helps!
The Son Doong cave is the largest cave in the world. This cave is located in Quang Binh province,Vietnam.
It is in central Kentucky near Brownsville.
Mammoth CaveADDED: Depends on how to defines largest; but Mammoth - Flint Ridge Caves system has certainly world's longest knowntotal of surveyed passage length, I believe now >400 miles.
The Mammoth Cave system, located in Kentucky, is the largest cave in the world.
