Starting Point and Transportation
Your adventure begins with a round-trip transfer from Coyhaique, a common hub for exploring Patagonia’s northern reaches. The transportation is straightforward, removing the hassle of navigating remote roads on your own. The guide, often bilingual, will meet you here, setting the tone for a well-organized and smoothly run trip.
The First Day: Into the Wilderness
The trek officially kicks off in Cerro Castillo National Park, a less-visited corner that rewards explorers with untouched scenery. As you begin hiking, you’ll traverse rugged trails that wind through ancient lenga forests—these forests are typical of Patagonian landscapes and add a cool, shaded contrast to the open vistas.
Expect your guide to share insights about the local flora and fauna, enriching your understanding of this special environment. We loved the way the landscape gradually opened up to reveal the notorious Cerro Castillo itself—an imposing, rugged mountain that’s become a symbol for Patagonia’s wild spirit.
Day Two and Three: Scenic Highlights and Wildlife Encounters
Over the next two days, you’ll cover about 55 kilometers of varied terrain, passing glacial lakes with remarkably clear, turquoise waters—perfect spots for photos or a quick rest. The terrain includes steep sections, so comfortable hiking shoes and weather-appropriate clothing are essential.
One of the standout moments, according to travelers, is witnessing views of Cerro Castillo from different angles—each perspective offering a fresh appreciation for its majestic form.
