By far the most popular sight in the park and accessible from the park’s main entrance, is the incredible Ventisquero Colgante, or “hanging glacier”. Wedged between two peaks, forming a V-shaped mass of blue-white ice, the glacier indeed seems to hang suspended over a sheer rock face. Long fingers of ice feed two thundering waterfalls that plummet 150m down to a glacial lake. From the parking area by the Centro de Información Ambiental, follow the signposted 250m Sendero Miradór Panorámico to a spectacular viewpoint. If you cross the suspension bridge over the river and turn right, you will find the 600m Sendero Laguna Témpanos, which leads to its namesake lake through dense native forest, from where you get excellent views of the glacier.
Left of the bridge, the steep Sendero Ventisquero Colgante climbs 3.2km to a higher viewpoint. Another trail, the 6km Sendero Valle Río Ventisqueros, starts at the same car park and follows the southern bank of the Río Ventisquero Valley, passing through evergreen forest and numerous viewpoints overlooking the Ventisquero Colgante before ending up at a beautiful beach. Allow five hours for a return trip and consult the rangers regarding trail conditions.
