This spectacular Marble Cathedral, an intricate system of water-filled caverns, is set in the General Carrera lake in Chile's Patagonia - the second largest freshwater lake in South America.
But to reach this remote place, located in the far southern tip of the country, visitors must fly from the capital Santiago, 800 miles to the next nearest large city, Coyhaique, and then drive on challenging dirt roads 200 miles south to the lake.
To get to the caves, one must embark on a long and difficult journey starting from a flight to the Chilean capital of Santiago. Visitors must then travel an 800 miles on major highways to the next big city Coyhaique, followed by a 200-mile drive on rough dirt roads towards the lake. Finally, a boat is needed to access the caves. But though the journey is long and challenging, many agree the enchanting beauty of the caves is definitely worth the effort.
