Catedral de Mármol, Natural marble formation on General Carrera Lake, Chile.
The marble cathedral consists of caves and tunnels formed by calcium carbonate deposits, displaying intricate patterns along the lake's shoreline.
Over 6000 years of constant wave action from General Carrera Lake carved these natural marble caves into their current geological structures.
Local fishermen from Puerto Rio Tranquilo share their knowledge of the caves by guiding visitors through the marble formations in small boats.
Tours to the marble caves depart from Puerto Rio Tranquilo between September and March when water levels allow optimal cave access.
The mineral composition of these caves creates walls with swirling patterns of gray, blue, and white, reflecting in the glacial waters below.
