Bengdwigul Cave - with a total length of 2.8 miles, Bengdwigul Cave is shaped like a maze and is one of the most complex structures of a lava tube in the world. For geologists, this cave is invaluable since it demonstrates how lava continuously flowed over the surface of the ground and the complex route it took to eventually form a tube deep underground. Created particularly close to the earth’s surface, this cave has a number of entrance holes throughout the length of its tunnel; however it is closed to the general public. Inside, the complex structure of the cave unfolds in the form of double-tiered or triple-tiered rooms. A range of lava formations such as lava columns and lava bridges have developed inside this mystical tube. This cave is a registered as a World Heritage Site of UNESCO.
