A cool wind pushes through lenga and coihue as the trail opens onto a river that seems to lead straight to a green mirror. The path rises and falls across peat-stained hummocks, crossing wooden plank bridges and narrow streams until the bright, sediment-heavy water of Laguna Esmeralda appears, glacial-born and startling against the dark mountains.
