Lying 15km east into the mountains from Fiambalá, these thermal springs emerge from rock and cascade down the mountainside in a series of pools: the highest is around 40ºC; the cooler ones are below. The views over the desert valley are epic. It's best after 5pm when there's more shade. Weekends are rowdy. There's a campsite and various simple accommodation options here. It's AR$170 in a remise from Fiambalá.
