Mount Fitz Roy (Cerro Fitz Roy)

The trek to Laguna de los Tres is one of the primary day activities in Los Glaciares National Park, providing a close-perspective view of the granite massif of Mount Fitz Roy (3,405m). The route follows an out-and-back trail through mixed forest and glaciated valleys, passing the Piedras Blancas viewpoint before the final ascent. The journey is defined by a significant transition from the low-lying valley floor to the high-alpine environment of the lagoon, which sits directly below the main peaks.

Consistently ranked as one of the best treks in the world, the Santa Cruz weaves through the heart of the Cordillera Blanca. Surrounded by dozens of 6,000-meter peaks—including Huascarán, Peru's highest mountain, and Alpamayo (often called often regarded as one of the most beautiful mountain)—this 3-to-4-day route cuts a dramatic path over the soaring Punta Union pass at 4,750m. Hikers traverse surreal turquoise glacial lakes, sprawling alpine meadows, and desolate moraines in a truly formidable high-altitude environment.
