Why it's incredible: The marble walls reflect the turquoise color of the water in the cave, tinting them blue.
The Marble Caves are natural rock formations with curved walls covered in swirling mineral patterns. They sit on the shores of General Carrera Lake, a glacial lake in southern Chile. The lake floods the caverns with turquoise waters, which fill the caves with blue light and give them an ethereal appearance.
