The Marble Caves Of Patagonia, Chile

Dubbed as the most beautiful cave network in the world, Cuevas de Marmol is a 6,000 year-old sculpture hewn by the crashing waves of Lake General Carrera of Patagonia in Southern Chile.

Also called the Marble Cathedral, the intricate caverns are part of a peninsula made of solid marble surrounded by the glacial Lake General Carrera that spans the Chile-Argentina border. The swirling pattern on the cave interiors are a reflection of the lake's azure waters, which change depending on the water levels dictated by weather and season.
