Departing from Puerto Natales, board a crossing to the Ultima Esperanza fjord, reached after two hours. Once there, you'll see Mount Balmaceda (2,035 m), at the foot of which the immense frozen waterfall of the glacier of the same name has been flowing for millennia. The cracking sound of ice breaking off the glacier and falling into the fjord is striking.
Sailing through a unique mix of green slopes covering the mountains and turquoise waters merging with the towering glaciers, you'll be able to spot sea lions and cormorants. Go ashore for a short walk of about one kilometre through a forest of native trees, leading to the foot of the majestic Serrano glacier, where you'll take in this natural wonder.
