Exploring Tronador Foothills



This four day backpacking traverse along the foothills of Tronador Mountain will provide some amazing views of its hanging glaciers, overnight by an alpine lagoon and climb a scenic summit with the most dramatic mix of forest, lakes, glaciers and shear granite walls.

This hiking trip can be done using camping tents or a combination of Mountain Hut and Domes for each night in the wilderness. The hike starts at Pampa Linda area, located two hour drive from Bariloche and in the hart of the mountain range.

Day one is a 4 hour trek up to Ilon alpine Lagoon, on a well-marked trail covering different native forests. You will enjoy the firsts views of Tronador glaciers and impressive waterfalls. After gaining elevation on the switch backs, you will cross a beautiful meadow and continue towards the lagoon. Suddenly, the reflection of the mountain on the lake will mark the end of day 1 trek. Overnight and time to relax , maybe go for a swim!

Day two is the longest trek and does demand an early start so you can enjoy each stop on the way. You will be astonish by “Mirada del Doctor” lookout and the views from “Mar de Piedras” ridge. Hiking towards the glaciers makes the day very amusing and each hour you feel closer to the carving ice. After some ups and downs on the beach forest, you will gain the famous pass called “Paso de las Nubes” (Cloud Pass) Here you will overnight camping or at the hut called Refugio Rocca.

Day three, time to summit Cerro Constitución! This is a beautiful trek along its ridge overcoming snowfields and rocky slabs. The views get more and more impressive as you climb and suddenly you can recognize part of Nahuel Huapi Lake even though you are ways away. The day trek finishes enjoying the glide of Andean Condors right above you.

The last day in the mountain you will be descending back to Bariloche. There are two ways to do this, option A is to take the traditional trail up to the Mountain Hut and descend to Pampa Linda and drive back to the city. The other option is taking the trail that leads to Frias Lake which is a longer hike down a beautiful example of “Valdivean temple rainforest” discovering new species of plants and trees because of the high volume of rainfall this valley receives. Once at Frias lake, you will take a small commercial boat for 30 minutes and connect with a short bus drive followed by a second longer and even more beautiful passenger cruise on Bless branch of Nahuel Huapi lake. The ship navigates directly to Bariloche providing an incredible opportunity to sail this huge Patagonian Lake!
