Day 1: Arrival to Aysen Region and Transfer to Cerro Castillo National Park. Trek begins.

Balmaceda and Villa Cerro Castillo, Chile

Welcome to Patagonia! Following a two and a half hour flight from Santiago to Balmaceda Airport, we will pick you up and take a scenic drive to the town of Cerro Castillo in Northern Patagonia.

Here we'll begin the adventure by hiking approximately 15 kilometers along the trail known as “Las Horquetas.” We'll follow an old logging road for about two hours, which gently winds through the mountain valley and passes the camps of local gauchos who used to take their livestock into the mountains in the summer months. We will make the first stream crossing here and get a glimpse of the crystal clear waters of Patagonia.  

At the reserve entrance, we will register our details with the park administration and then continue hiking 2 km, until reaching Camp Turbio and setting up tents for the night.

Overnight at Camp Turbio

Day 2: Challenge: Portezuelo El Peñón

After a restful sleep, the second day of trekking begins! We'll the Turbio River through the valley until the ascent into the mountains. We’ll then cross Pinon Pass, which has an altitude of 1,300 meters and has a challenging descent along loose, steep rock scree and even a small amount of snow (except February and March).  

After making our way past the hanging Pinon Glacier and over the pass, we will arrive at the campsite, La Tetera Camp, where we can settle in and rest until the next day.

Day 3: Cerro Castillo Lagoon and transfer to Balmaceda Airport.

After an early start, we'll continue to the famous lagoon of Cerro Castillo. We can take a short break here to take in the scenery and marvel down at the valley we've spent the last two days hiking through.
