Explore Stunning Marble Caves in Chile
When most people see photos of Chile‘s Marble Caves for the first time, they think that they must be looking at a photoshopped image with a slick filter. Photos of turquoise water lapping against swirling marble arches streaked with ribbons of pale yellow, sea green, and deep blue appear too vibrant and beautiful to be real. The splendor of the Marble Caves has inspired some admirers to refer to them as a Marble Cathedral.
Located on remote Lake General Carrera—which is a glacial lake situated on the border of Chile and Argentina—the Marble Caves were formed when mineral-rich water crashed against marble rocks for thousands of years. The waters of Lake General Carrera are a striking shade of blue thanks to deposits from a nearby glacier. The smooth walls of the Marble Caves appear to be an arresting shade of blue when sunlight shimmers on the vibrant waters of Lake General Carrera.
The Marble Caves are located in the remote Chilean region of Patagonia and can only be accessed via boat. Several tour companies offer kayak and boat tours for visitors to explore the caves. The Marble Caves are a photography lover’s dream come true, as the ornate formations, textures, and constantly changing colors of the caverns create magnificent images that are impossible to duplicate because the light is forever changing.
Visitors can also explore nearby Cerro Castillo National Park, which is home to jagged peaks, winding hiking trails, and plentiful wildlife such as pumas. The Carretera Austral—a scenic road that winds through Patagonia—is also located near the Marble Caves. Patagonia is filled with gorgeous scenery, but there are few places on Earth that are as spectacular as the Marble Caves. Be sure to pack a camera because the beauty of the Marble Caves will instantly transform you into a star photographer.
