Thongs to do in Marble Caves

Although its official name translated to Spanish is Marble Chapels (Capillas de Mármol), you can find different rock formations and caves in the lake. The largest one is called Catedral de Mármol (Marble Cathedral) and many know the place by one of these names.

Declared as a Nature Sanctuary in order to protect them, these mineral formations composed of calcium carbonate and located on the shores of General Carrera Lake, the largest in Chile, have been eroded over millions of years by water and wind, exposing the marble as they can be seen today.

The beauty of the place and the tourist attraction is given by the visit to the caves that were created by the erosion of the lake water on the rock and where you can observe the different shades that acquire the rock formations along with the turquoise color of the lake water.

You will also notice the imposing formations over the lake known as the Marble Cathedral and the Marble Chapels.

Best time to visit Marble Caves

Although the excursion can be done all year round, the best time to visit the Cathedral and the Marble Chapels is during the autumn and spring of the southern hemisphere. In summer the water level of the lake rises and it is often impossible to enter the caves with the boat.

In the middle of winter, due to the cold and the low number of tourists, the offer is considerably reduced and it may happen that there is not the minimum of five people required to go on the excursion.

Getting to Marble Caves

There are three options as a starting point to do the excursion to the Marble Caves.

  • Contract a tour with a travel agency in Puerto Río Tranquilo, a small town where there is a lot of offer. From here, boats leave on General Carrera Lake to the Marble Caves.
  • Go on your own to Bahía Mansa, five kilometers south of Puerto Río Tranquilo, where there are boats and kayaks with guides and cheaper prices. In addition, navigation on the lake to reach the Cathedral and the Marble Chapels is much shorter. On the downside, be careful with the road that goes down from Route 7 to the bay (it is a kilometer and a half) because it is steep and is usually in pretty bad conditions.
  • Hire a tour from Coyhaique, 220 kilometers north of Puerto Rio Tranquilo. We only recommend this if you arrive by plane to this area of the Carretera Austral from Balmaceda airport and you are not going to visit any attractions south of Puerto Rio Tranquilo. In this case, the excursion is a full day trip.

– Arriving from Argentina

The Marble Caves can be visited from Argentina by car. To do this, take Route 40 to the town of Perito Moreno (not the glacier). Then Route 43 that borders General Carrera Lake to Los Antiguos, the border crossing to Chile.

The first town on the Chilean side is Chile Chico. From here along Route 265, which also borders the lake and Route 7, you get to Bahía Mansa or Puerto Río Tranquilo, where the excursions to the Marble Caves start.

From Perito Moreno to Puerto Río Tranquilo there are 240 kilometers, of which only 60 kilometers are paved, rest is gravel. The duration of the trip may vary according to weather conditions (we don’t recommend doing it in winter) and the time it takes to get through customs on the Argentinean and Chilean side.

Also keep in mind that there are many curves, downhills and uphills on this road.

📷 If you are visiting from Argentina, there is a full day excursion that includes transfers, boat or kayak, snack and lunch, departing from Los Antiguos or from the town of Perito Moreno. Highly recommended!
