The scenery on both sides of the fjord is quite similar to the canals on the southern side of Tierra del Fuego Island.
Port Blest, at the western end of the arm, is reputed to be one of the rainiest spots in Argentina, with an annual rain average and snowfall of nearly 140 inches. This explains the very lush vegetation and the temperate rain forest.
As an additional to this tour, we will continue on a ten minute bus ride southwards to Puerto Alegre on the Frías Lake. Here we’ll embark again to sail on Frías Lake for fifteen minutes. On this ride we’ll have the first view of Mount Tronador. At Port Frías, passengers will have to go through Argentine Customs. We’ll then continue by bus through the exuberant vegetation of the Andes Range, crossing the Argentinean-Chilean border at Vicente Pérez Rosales Pass, and driving 29 km. till we arrive at Peulla. Passengers will have to go through Chilean Customs at this point. The tour continues on catamaran along Todos los Santos (All Saints) Lake, from where we can admire Puntiagudo Mt. and the impressive Osorno volcano. Upon arrival at Petrohué, we’ll get on the bus again. We’ll make a stop at the Petrohue Falls , and then, going round Lake Llanquihue, we’ll be arriving to Puerto Varas. Twenty minutes later will be getting to our final destination on this breathtaking lake-crossing, namely, Puerto Montt.

Two-day crossing: The circuit is the same as described above, except that one overnight at Peulla (Chile) is included.
