“Catedral de Marmol” – Patagonia Chilena

Marble Cathedral (located next to the Marble Chapel) is a mineral formation of calcium carbonate, on the shores of Lake General Carrera in Chile. In 1994 it was named a national monument. Over the years, the lake waters have eroded coastal cliffs, creating these formations, which when the lake is at a low level, you can go inside in small boats.

It consists of a few islets located a few meters from the lakeshore, which are named Marble Cathedral, Chapel of Marble and Marble Cave.

You can access these formations through the lake in small boats from the town of Puerto Río Tranquilo (in the municipality of Rio Ibanez, 223 km from Coyhaique, capital of the Aysen region). From here you can rent small boats, which run through the area of Marble Cathedral.
