Among the innumerable options that the Nahuel Huapi National Park offers, there is a little-known route but no less spectacular for that.
From Bahía López, 25 km from Bariloche, you can get to the Brazo Tristeza by motor boat. There, if the day is clear, you can see the glaciers at the top of Cerro Tronador, the highest in the park. When we reach the end of this Arm, we descend to land to walk a path through a dense forest, in which species known as the coihue and the cane alternate. Then we arrive at the Frey Stream Cascade. The flow of this stream varies according to the time of year, producing a peculiar and characteristic sound, which is generated when the water runs between wells, on a bed of rock polished by years of erosion.
