Carved into the Patagonian Andes, the Cuevas de Mármol (Marble Caves) are located on a peninsula of solid marble bordering Lake General Carrera, a remote glacial lake that spans the Chilean-Argentinian border.
Formed by 6,000-plus years of waves washing up against calcium carbonate, the smooth, swirling blues of the cavern walls are a reflection of the lake’s azure waters, which change in intensity and hue, depending on water levels and time of year.
The caves are accessible only by boat. Boats run from outside Puerto Rio Tranquillo or Chile Chico.
For photography, the caves of streaked marble provide fantastic photo opportunities, especially if your interests lie in abstractions and the interplay of negative and positive space.
