Hell Hole

Hell's Door
Kara Kum Desert, Turkmenistan

It has a beautiful view especially at night since its glow is visible miles away. This was a result during an excavation on 1971 for natural gas but the floor collapse like a sink hole and then the authorities decided to ignite the cave rather than letting the gas fume out and poison people. As a result a never ending glow due to a burning natural gas.

The Great Blue Hole

This natural sinkhole lies 60 miles off the coast of the Central American country of Belize. Formed when sea levels were much lower, it was originally a limestone cave.
As sea levels rose, the cave collapsed, leaving a hole more than 300 metres across and 125 metres deep. Jacques Cousteau declared it one of the best dive sites in the world.
