HERNÁN RIOS

Guide: Aconcagua

At the core of Hernán’s life is a profound love for the outdoors and an insatiable passion for exploring the world’s most beautiful wilderness areas. For Hernán, being a mountain guide is not just about numbers or years on a resume; it is about the pure joy of movement, the thrill of discovering new places, and sharing the deep freedom that only nature can provide.

​Rock climbing has been his lifelong sanctuary and a gateway to global exploration. He has spent years traveling and deeply exploring iconic crags and massive walls across France, Spain, Italy, Chile, Bolivia, and Peru. Among his most cherished memories are the countless pitches scaled in world-class destinations: from the legendary granite walls of Cochamó and the massive east face of La Esfinge in Peru, to his home climbing paradise in Arenales (Mendoza). His vertical journeys have taken him from the seaside limestone of Sardinia (Italy) and Sadernes (Spain) to the pocketed walls of Siurana and the conglomerates of Montserrat. Whether bouldering in the magical forests of Fontainebleau (France), exploring the volcanic rock of Valle de los Cóndores (Chile), enjoying the endless pockets of Piedra Parada, or climbing at high altitude in Hatun Machay (Peru) and El Edén (Bolivia), Hernán thrives on the diverse beauty of the vertical world.

​When winter arrives, his passion seamlessly shifts to the snow. Hernán loves spending his winters chasing perfect powder days between the majestic slopes of Argentina and Chile. For him, nothing compares to the serenity of ski touring (randonnée) through the imposing Andean peaks, mapping out clean lines in fresh snow and enjoying the mountains in their most wild, winter state.

​His connection to nature doesn’t stop at the summits. During the summer, Hernán loves to slow down and immerse himself in the sea, enjoying the crystal-clear waters of the Mediterranean Sea as a certified PADI Open Water Diver. This dual love for the highest peaks and the depths of the ocean reflects his lifestyle: a dedicated explorer who simply loves to live in harmony with the elements. Hernán brings this vibrant energy, love for adventure, and global perspective to every Alpine Ascents international expedition, inspiring climbers to not just reach the summit, but to deeply enjoy every step of the journey.
