It is the most direct way to get to Chaitén from the continent since there is no continuing road between the two cities, separated by fjords. Leaving Puerto Montt, the ferry crosses the interior sea of the Chiloé archipelago, through calm waters protected by the Isla Grande of Chiloé. With good visibility, it is possible to see a chain of high summits and volcanoes on the continent. There are about 6 services per week. Unfortunately, most trips are done during the night, which spoils the chance to enjoy the view.

This journey is made by Naviera Austral with its vessel Agios. It carries cargo, vehicles, and passengers since the maritime route is one of the best transport and communication options in the zone. The ship has space for 300 passengers on comfortable seats, but no berths nor cabins.

Usually, there is space for passengers until shortly before the departure. However, if travelling by car, it is important to make the booking ahead, especially during the summer holidays.

The Agios ferry has 300 pullman-type seats with USB ports on the side to power electronic devices. It has a spacious passenger room with large windows to enjoy the beautiful landscapes of your route; It offers satellite TV, air conditioning, bathrooms for men and women, a bathroom for the disabled, and two cabins with showers. Next to this room is the cafeteria, which offers a wide range of products.
There are seats on the upper deck so the passenger can enjoy the trip, comfortably observing the beauty of the landscape outside.
