Este servicio en todos los casos se abona extra a la navegación a Puerto Blest. En caso de utilizar un solo tramo de navegación, este se tiene que abonar en su totalidad (ida y vuelta).

Para este trayecto de navegación también se pueden contratar servicios privados de navegación. En tal caso es importante verificar que las embarcaciones y las empresas estén debidamente habilitadas por la Administración de Parques Nacionales para brindar el servicio.

Hotel Puerto Blest

Temporada baja. Desde Semana Santa hasta el 14 de diciembre. En este período puede haber días en que el Hotel permanezca cerrado. El resto del año se considera temporada alta. En caso de reservar el hotel el costo del viaje en catamarán se encuentra incluido en la tarifa, ya sea que se utilicen los dos tramos (ida y vuelta) o sólo uno de ellos.


The trail starts right next to the hut, it is very well marked all the way. The trail descends through a Lenga forest and close to getting to the valley floor there is a big rock outcrop with great views of the hanging Frias glacier. From here it is a rocky trail down to the valley. You cross a small creek (bridge) and continue through the Valdivian forest staying always on the right side of the Frias river. After roughly 9 km. there is a hanging bridge to cross the Frias river.

The ticket for the boat ride can be purchased in Bariloche before starting out with a fixed date or reserve up at the Agostino Rocca Hut. This option is best so as to have some flexibility on dates, either way make sure you have a reservation for the boat.

You will navigate Lake Frías from Puerto Frías to Puerto Alegre, then a short bus ride to Puerto Blest and finally the last leg from Puerto Blest to Puerto Pañuelo. (all included in one ticket).

This trail can also be done in the opposite direction, starting at Puerto Blest and finishing in Pampa Linda staying the night at Agostino Rocca Hut. On either direction you can also include a night stay at the Hotel Puerto Blest to enjoy its surrounding trails.

To improve the trekking experience, it is recommended to contact a Mountain Guide authorized by the AAGM (Argentine Association of Mountain Guides)

  • Camping is not allowed at Lake Frias nor at Puerto Blest.
  • The trail has markings (01/12, 02/12, 03/12) which indicate the distance you have covered, this will help calculate the time needed to get to the pier in time for the boat.
  • Have always in mind the boat departure timetable.
