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.
Visitors are enamored by the Marble Cave’s unique ability to constantly change its appearance. In early spring, the shallow waters are turquoise and creates a crystalline shimmer against the caves’ swirling walls. Come summer, the water levels increase and create a deep blue hue which gives the cave a unique unearthly shade. The water levels are significantly affected by the freezing and melting of the surrounding glaciers. It’s also from these glaciers where the lake takes the fine silt sediments that rest on the lake bed.
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.
