This circuit (1400m) descends to the river, passing delightfully close to falls on the way. At the end of the path prepare for a drenching at the hands of Salto Bossetti if you're game. Just short of here, a free launch makes the short crossing to Isla San Martín. At the same junction you can buy tickets for the popular boat rides under the falls.
