Capillas de Marmol near Puerto Rio Tranquilo in southern Chile is a stretch of marble cliffs and freestanding rock islands carved into hollow chambers at the edge of Lake General Carrera. Protected as a Santuario de la Naturaleza since 1994, the formation sits in the Aysén Region and is reached entirely across the lake’s surface.
Marble, lake and light at Capillas de Marmol
Capillas de Marmol lies on the western shore of Lake General Carrera, a large glacial lake shared between Chile and Argentina in the Aysén Region of southern Chile.Lago General Carrera in Aysén The rock itself is marble, a carbonate formation whose pale surfaces are exposed directly to the lake, forming cliffs, projecting headlands and small islands.
The name Capillas de Marmol refers not to a single cave but to a group of formations, known locally as Catedral de Mármol, Capilla de Mármol and Caverna de Mármol, spread along a short section of the lake shore.Catedral, Capilla and Caverna de Mármol At lake level the marble is cut into arches, recesses and chambers where the water meets the stone, creating shaded hollows that are directly open to the lake.
Catedral, Capilla and Caverna: the core formations
The Catedral de Mármol is a marble outcrop attached to a low peninsula on Lake General Carrera, its base sculpted by the lake into recesses and passages that are accessible only from the water.Catedral de Mármol on the lake Nearby, the Capilla de Mármol forms a small marble island separated from the shore, rising from the lake with eroded marble at its base and vegetation on its upper surface.
The Caverna de Mármol name is used for caves along the same section of coast, where the marble cliffs are hollowed at the waterline into chambers that can be entered by small boats and kayaks when lake conditions permit.Marble Caves on General Carrera Lake Taken together, these three labels have become shorthand for the wider group of marble formations known in English as the Marble Caves of General Carrera Lake.
