Operator's Itinerary

Day 1: Transfer from Balmaceda to Cerro Castillo; La Casona

After your 2.5-hr flight from Santiago to Balmaceda, you'll be met at the airport and take a 1.5-hr scenic transfer to the town of Cerro Castillo. You'll be taken to your accommodation, La Casona, where you'll enjoy a private suite in an antique house. After settling in, you'll be picked up to head to town for dinner at a local restaurant and a meeting with your guides for the trek.

Transfer duration: 1.5hrs

Meals: Dinner

Accommodation: La Casona

Day 2: Trek to Cerro Castillo National Reserve; Camp Turbio

The first day's trek follows an old logging road for about 2hrs. We'll pass old gaucho camps that were used to take livestock to the mountains in the summer months and we'll get a glimpse of the first crystal-clear waters of Patagonia. Finally we'll reach the Cerro Castillo National Reserve entrance, pass the park office, register, and continue for the last 2km to Camp Turbio where we'll spend the night.

Length of trek: 15.4km, 6hrs

Meals: Breakfast, picnic lunch, dinner

Accommodation: Camp Turbio

Day 3: Trek to Glacier Pinon; Camp Bosque or Camp La Tetera

Our second day begins by following the Turbio River through the valley before beginning an ascent into the mountains. We'll cross the Pinon Pass at an altitude of 1,300m and negotiate the tricky descent on loose scree. The guides are excellent at pointing out the trail and we'll take a route alongside the hanging Glacier Pinon. Except for the months of February and March, you can expect to have a small amount of snow through the pass, but not on the descent. It's easily hike-able and is actually easier than hiking over the loose scree. After crossing the pass and arriving in the valley below, we'll have the option to camp at Camp Bosque, or continue for another 2km to the more scenic Camp La Tetera. This decision will be decided during the trip with your guides and depends on how you are feeling after crossing the first pass.

If we continue to Camp La Tetera, we can take a hike up to the glaciers in the evening. In the morning you can wake up early for some awesome shots of the sunrise coming up over the peaks of Cerro Castillo.

Length of trek: 9.5km, 6hrs (not including optional side-trail)

Meals: Breakfast, picnic lunch, dinner

Accommodation: Camp Bosque or Camp La Tetera

Day 4: Climb Morro Negro; Camp Porteadores

If we camped at Camp Bosque last night, we'll continue to La Tetera where we'll have a short break. From here we'll trek to Lake Cerro Castillo where we'll stop to take in the scenery before climbing up Morro Negro, peaking at 1,700m, and descending down steep rock scree to arrive at Camp Porteadores.

Length of hike: 8.8km, 6hrs

Meals: Breakfast, picnic lunch, dinner

Accommodation: Camp Porteadores

Day 5: Trek to Cerro Castillo viewpoint; Cerro Castillo; La Casona

We'll begin our last day by taking a short hike, without packs, to the upper camp, Camp Neozelandes. Here we can soak up the views of the north face of Cerro Castillo and the glacial basin that is made up of Cerro Palo and Castillo. This area of the reserve is stunning and, if it is warm enough, you can continue to Lake Yagan for a quick dip in the glacial waters.

We'll head back down to our packs and continue descending down the mountain back to the trailhead and road to Cerro Castillo. The hike down is easy, through southern beech forest, and only 4.3km from where we left our packs at Camp Porteadores.

After we reach the trailhead, we'll be taken to a local spot for dinner (not included) and then back to La Casona in Cerro Castillo where you can have a full night's rest.

Length of hike: 11.5km, 7hrs

Meals: Breakfast, picnic lunch

Accommodation: La Casona

Day 6: Transfer to Balmaceda Airport
