CUEVAS DE MARMOL
On the border between Argentina and Chile in Patagonia, freshwater mermaids frolic in an astoundingly colorful Marble Cave Cathedral. These intricate marble caverns were hewn by the waves of the glacial-fed Lake General Carrera over thousands of years. Glacial silt helps make the water shine with an insane vibrant blue.
The different colors bouncing off the walls and water depend on the lake’s seasonal water levels; shallow waters create a lighter blue, while deeper waters will result in a darker blue.The caves accessible by boat only are best seen at sunrise or sunset. Check out a video tour.
