Onda Azul is a hostel situated on the bank of the Río Azul in Chubut, Argentina, near the town of Lago Puelo. It serves as a notable waypoint on the Andean Circuit's Stage 32, a 14. 9-kilometer route of low difficulty that is accessible year-round.

The property sits along the river's flood barrier and is reached by following an old gravel road that runs down to the riverbank from the paved highway connecting El Bolsón with Lago Puelo.

From Onda Azul, trekkers continue along a local street toward the Lago Puelo Tourism Office before proceeding to Lago Puelo National Park.
