When we first see the great granite pinnacles of Torres del Paine it is worth remembering that the Andes is the youngest chain of mountains in the world. One can imagine the great pressures and movements of the earth that created these spectacular vertical peaks. The trekking starts on the slopes of the Almirante Nieto Mountain that borders the River Ascensio. We make a pronounced ascent to arrive at the River Ascensio Valley and then a further two hour climb to reach the Chilean refuge. We continue our walk crossing the forest of coihues, a Chilean evergreen used for thatching, with the objective of reaching the base of Las Torres. This is popular point for the mountaineers to begin their climbing, with vertical faces of more than 880 metres. Later we arrive at the Las Torres viewpoint, a natural amphitheatre with magnificent views that is situated at the base of the vertical granite towers that are more than 2,700 metres high. Here we can see la Torre Sur, Central y Norte, el Nido de Cóndores and the North face of the Almirante Nieto Mountain. Also we can see la Morena, a rocky formation, that has an altitude of 1,000 metres. Finally we return by the same path. Duration: 7-8 hours round trip. Accommodation at Las Torres Inn.
