About this experience

The experience begins at Puerto Bahía Túnel , just 18 km from El Chaltén , Argentina's trekking capital. From there, we embark to navigate the turquoise waters of Lake Viedma , surrounded by an imposing landscape where the sky, mountains, and ice merge into a single Patagonian postcard.

During the crossing, the boat hugs the southern shore of the lake, offering unique views of the Huemul Massif, one of the region's most iconic mountains. After about 40 minutes, we arrive at Cape Horn Bay , where we disembark for an easy hike to a stunning viewpoint.

From there, the view opens up to Iceberg Bay , where blocks of ice drift against the majestic backdrop of the Andes Mountains . It's a natural spectacle that combines silence, wind, and beauty in its purest form.

Then we returned to the boat to experience the most breathtaking moment: approaching the face of the Viedma Glacier . From the deck, you can contemplate the full magnitude of the glacier—its bluish hues, the deep crevasses, and the sound of the ice slowly cracking—while the guide explains its history, its geology, and the evolution of this ancient colossus.

Finally, we begin our return to the port with a profound sense of awe and connection to nature. An experience that combines adventure, contemplation, and the immensity of Patagonia at its finest.
