After pickup from your accommodation in Bariloche, board a comfortable coach and enjoy the scenic drive to Puerto Pañuelo.
Upon arrival at the port, board your waiting vessel and set sail on Nahuel Huapi Lake toward Puerto Blest, located about an hour away. Learn about the surrounding forest and its abundant bird life from your guide as you enjoy the alpine scenery.
Board a bus at Puerto Blest for the trip along the Frías River to Puerto Alegre. Sail aboard another boat on turquoise Lake Frías in the shadow of the majestic Cerro Tronador, the region's highest mountain and host to nine glaciers. At Puerto Frías, you'll go through Argentine customs before continuing to Peulla, Chile, by bus.
Enter Vincente Pérez Rosales National Park in Chile and arrive in Peulla, where you can enjoy lunch (own expense) after completing the official entry to Chile.
In late afternoon, set sail on Todos los Santos Lake, with marvelous views of Osorno Volcano, Puntiagudo Hill and Cerro Tronador if the weather cooperates. Continue to your destination, Puerto Varas, with an optional stop at Saltos de Petrohué (Petrohué Waterfalls; admission not included.)
