Turbio IV - Adventure and climbing in a lost valley of Patagonia

In 2023, Vianney, co-founder of Peak Patagonia and a international team of climbers went on an ambitious expedition to the remote Turbio IV Valley. Their mission? To climb the untouched big walls of pristine granite in one of Patagonia’s last unexplored areas. This adventure included a blend of hiking, zip-lining, horseback riding, river crossings, climbing, and packrafting, offering an immersive experience in the heart of northen Patagonia’s wild landscapes..

The Journey begins with Vianney’s dream to explore the Turbio IV Valley, in 2016 after watching a movie about the region. However, finding information on this secluded area proved difficult, with no GPS coordinates or reliable maps available. Over the next few years, Vianney gathered information, connected with local explorers, and met Belén, his future climbing partner. Together, they pieced together a plan to explore the "Lost Valley." A chance encounter with John Collis while crack climbing in Arenales Valley completed their core team, and soon, other passionate climbers joined, bringing the dream of the expedition to life.

The Team

The Babel Expedition was composed of eight climbers from around the globe—representing Argentina, Chile, Brazil, the U.S., the U.K., and France. The multi-lingual team split into three groups, each focused on opening new climbing routes on distinct granite formations. Their goal : having fun and finding the best crack climbing on this untouched terrain.

The final expedition team included: - John Collis - Mike Coyle - Gareth "Gaz" Leah (the team's photographer) - Jose Luis Hartman (aka Chiquinho) - Belén Prados - Vianney Lhoumeau - Oscar Marin - Andrea Caceres.

Each climber brought unique skills and experience, contributing to the success of the mission.

 The Adventure

 For 18 days, the team tackled the rugged terrain of Turbio IV Valley, climbing virgin granite walls, navigating untouched rivers, and traversing the wilderness. One of the highlights of the expedition was the final day, when the team embarked on a 35-kilometer float down the Turbio River using packrafts. This peaceful journey gave the climbers a chance to rest and reflect on the adventure while enjoying breathtaking views. Their expedition ended with a boat ride across Lago Puelo, returning them to civilization.
