At 08:00 in the morning we leave Puerto Natales on the boat 21 de Mayo, and set sail through Última Esperanza Fjord. During the voyage, we enjoy the beauty of the fjords and observe cormorant and sea lion colonies as well as condors. After about three hours we arrive to Balmaceda Glacier, which pours from the summit of Mount Balmaceda into the sea. Here we have plenty of time to enjoy the view from the boat and snap some pictures.
About 20 minutes later we arrive to Puerto Toro, gateway to Bernardo O'Higgins National Park. Here we walk to the viewpoint of Glacier Serrano. If we are lucky, we’ll be able to contemplate the blocks of ice calving and splashing into the lagoon below.
After lunch at Hostería Monte Balmaceda, we will receive a warm waterproof outfit and life jackets to enjoy the next part of our adventure warm and dry. We board semi-rigid boats and head up the Serrano River (1:40 hours approximately) until we reach Salto Serrano (a geologic depression that makes for strong water rapids). This obliges us to leave the boat and take a short walk of five minutes, where we pass the rapid and board another boat to continue with the last 20 minutes of our trip, where we reach the Serrano River Sector of Torres del Paine National Park.
