Recommended activities in Santa Cruz
Boat trip among glaciers on Lake Argentino
In summer, the excursions that depart from Puerto Bandera let you enjoy longer days and deep-blue skies that highlight the bluish-white tones of the Upsala and Spegazzini glaciers. These boat trips take you incredibly close to huge ice walls, while local wildlife—such as cormorants, southern gulls and occasional penguins—accompanies the journey in a bright, vibrant setting.
Hike to the Perito Moreno glacier
Summer is the best time to visit the famous Perito Moreno glacier, one of the most accessible in the world. The walkways in Los Glaciares National Park allow you to explore it from different viewpoints, while the summer sun intensifies the turquoise reflections of the ice.
The most adventurous can opt for the classic minitrekking or the demanding Big Ice, guided hikes on the glacier that reveal crevasses, moulins and unique ice formations.
Hiking and trekking in El Chaltén
Known as Argentina’s trekking capital, El Chaltén offers fully open trails in summer, with pleasant temperatures and long days that are perfect for extended hikes. Routes such as Laguna Capri, Laguna de los Tres or Loma del Pliegue Tumbado provide breathtaking views of Mount Fitz Roy and Cerro Torre.
The meltwater lagoons turn intense shades of blue and green and the forests fill with colour, creating the perfect setting for photographers and adventure lovers.
Visiting Patagonian estancias
Estancia Cristina and other ranches near El Calafate come fully to life in summer. Visitors can go hiking, horse riding or 4x4 crossings to discover the rural history of the region and observe wildlife such as guanacos, Patagonian rheas, grey foxes and migratory birds that take advantage of the warm season to breed.
Tierra del Fuego: glaciers, forests and legendary routes at the end of the world
Tierra del Fuego, world-famous as the “end of the world”, reveals in summer its green landscapes, clear skies and ideal temperatures to explore forests, mountains and glaciers. Daylight stretches late into the evening, turning each day into an opportunity to go further and discover remote corners of this unique province.
