The cave also has its own climate, a river, a jungle, and plenty of sunlight for anyone bold enough find it. This cave isn't for the faint of heart - visitors need to rappel down 250-plus-feet to enter, and likely camp out for at least a night to conquer most of this huge cave system.

The list also includes other 10 famous caves in the world, such as: Batu Caves - Kuala Lumpur, Malaysia; Blue Ice Caves - Skaftafell, Iceland; Benagil Sea Cave - Algarve, Portugal; Waitomo Glowworm Caves - Waitomo, New Zealand; Tham Lot Cave - Mae Hong Son, Thailand; Marble Caves - Patagonia, Chile; Reed Flute Cave - Guilin, China; Cango Caves - Western Cape, South Africa; Fingal Cave - Staffa, Scotland; Carlsbad Caverns National Park - New Mexico.
