Welcome to the Marble Cathedral, a natural wonder that could be the world's most beautiful cave network.
An azure temple is created by nature. The walls of this network of water-filled marble caverns show just how magnificent the precious geography of our planet can be.
Visitors to the water-sculpted blue caverns see light reflected off the turquoise waters of South America's second largest freshwater lake, General Carrera in Patagonia, Chile.
How beautiful is this?
