This is an unforgettable trekking, starting from the small historic village of Colonia Suiza (Swiss Colony), 25 km west of Bariloche. Incredible views inside valleys and from mountain ridges, ascending peaks and getting closer every day a little more to Mount Tronador to touch its eternal glacier. Then, we complete the loop by motorboat on the Blest arm of Lake Nahuel Huapi to return to Bariloche.

Day 1: Hike from Colonia Suiza to Laguna Negra

Hike from Colonia Suiza to Manfredo Segre hut beside Laguna Negra (Black Lagoon). It’s a pleasant 14 km hike that starts very smoothly.  The last part of the trail, before reaching the hut, gets very steep and widing.

Day 2: Hike from Laguna Negra to Laguna Cab

We leave Manfredo Segre hut, surround the lagoon and hike up to the pass between Mt. Bailey Willis and Mt. Negro. We go down to the Brazuco stream, cross La Chata stream and hike up again to reach Laguna Cab (Cab Lagoon). We set camp and have dinner. Aprox 12 km, estimated time from 6 to 7 hours.

Day 3: Trekking from CAB Lagoon to Cretton Lagoon

We climb Mt. CAB to the ridge, we go down to the Mallin del Mate Dulce (swamp) and climb Mt. Cristales. When we descend from it, we will camp beside Cretton Lagoon. Aprox 14 km and estimated time from 6 to 7 hours.

Day 4: Trekking from Cretton Lagoon to Ilón Lagoon.

We continue west passing along the Azul and Jujuy Lagoons. We climb to the ridge of Mt. Capitán and go down to the Mallin de Ricardo (wet land). We keep going until we reach Ilon lagoon where we will set camp. Aprox 12 km, estimated time from 6 to 7 hours.

Day 5: Tekking to Paso de las Nubes

We surround Ilon Lagoon and hike to La Mirada del Doctor, one of the palces that probably has the best view of the whole traverse. The. we undo part of the trail and hike northwest, passing close to Mt. Mar de Piedras. We will be using a seldom used trail to reach Paso de las Nubes, extremely close to Mt. Tronador. We will have dinner in Agostino Rocca hut. Aprox 15 km, estimated time from 7 to 8 hours.
