We set sail from Hotel del Paine located in Villa Serrano, Torres del Paine”. We navigate the Serrano River, in zodiac type boats. This is fed by the melting of the Grey, Tyndall, Geike, and Balmaceda glaciers, after about 40 minutes of navigation we arrive at the Serrano River waterfall and where we must leave the Zodiac to walk through native forest for about 15 minutes until we find the second boat, we went to the viewpoint of the Tyndall Glacier (which is part of the Southern Ice Field) and then arrived at the Bernardo O'Higgins National Park. Where we will walk for about 30 minutes to reach the Serrano Glacier lagoon at the foot of Mount Balmaceda. We will have a small snack and return upriver, to enjoy a replenishing lunch at Hotel del Paine.
