This hike is one of the most accessible that can be done in the southernmost city in the world. The main aim is to reach the Emerald Lagoon. After leaving the hotel we go in the north direction, about 20 minutes from the city. Once arrived the guide will explain to us that we must cross the Lasifashaj Valley along a very clear and marked path, we will cross several peat bogs and rocky terrain. After a little more forest, we continue along the Esmeralda River until we reach the amazing Laguna Esmeralda, a small lake of glacial origin, which owes this name due to its color produced by sediments that come from the Ojo del Albino Glacier. This color can only be seen in summer, while in winter it will be frozen and covered with snow. While we enjoy the view of the Lagoon we will load energies eating box lunch. We will be able to undertake the return. Once the walk is over we will meet again with the vehicle that will be waiting for us to take us back to the city of Ushuaia.
