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.

  • This trail can only be done if you sleep at the Puerto Blest Hotel, so you must have a reservation at the hotel beforehand.
  • Camping is not allowed at Puerto Blest nor at Puerto Frias.
  • Bear in mind what season you are in, daylight hours, when planning your trip. Also be aware that in the rainy season the trails get very muddy and slippery making it a lot harder.


The trailhead is right next to the Hotel Puerto Blest. It goes around the bay, crosses a hanging bridge and joins into the boardwalk to Cántaros Lake.

After heading up the steps, continue to the end where you will see the old Alerce tree. Next to it is the trail that continues on to the Ortiz Basualdo lake.

The trail is well marked and crosses part of the Valdivian forest, with lots of vegetation, moss and lichens and you can observe many of these huge Alerces. This is a very humid ambient due to the high amount of rainfall and snowmelt, lots of lagoons and marshland where bridges and boardwalks have been built to avoid having to wade through all the creeks.

Roughly after 4 km. you will reach what is known as “La Heladera”, a huge granite vertical wall, where there is almost permanent snow and ice. Further on you can observe the Cántaros creek waterfalls, after passing a unique forest of Alerces and 9 km. you arrive at “Playa de los palos”, at the shores of the Ortiz Basualdo lake, at the mouth of Cántaros river which drains into the bay at Puerto Blest, Nahuel Huapi Lake.

Follow the same way down.
