Lionel Daudet and Isabelle Autissier are renewing their collaboration for a combined sailing and mountaineering expedition to the Antarctic Peninsula. The crew consists of three sailors and three mountaineers, whose skills complement each other perfectly. Departing from Ushuaia, their goal is to reach summits that have rarely, if ever, been climbed. Isabelle's boat, "Ada Dos," will serve as their mobile base camp. Ice, wind, and fog are just some of the obstacles that make both sea and land routes difficult, making access to the continent complex and unpredictable. The ascents are technical and require meticulous planning. Their only regret will be not being able to climb Pierre Premier, as the risks involved are simply too great.
