Are there natural hot springs in Sajama?

Yes, Sajama National Park is where you find pristine naturally heated volcanic hot springs, Termas de Sajama. They keep the bathing temperature near 35°C (95°F), so you can soak while you still get an uninterrupted sightline to the tall Nevado Sajama.

Meanwhile, compared with the crowded pools in Uyuni, the thermal baths around Sajama feel incredibly distant, calm, and pleasantly rustic. They’re looked after by local indigenous families, and the place asks for a small entry fee to use simple stone changing huts, so visitors can bathe in the steamy waters while alpaca herds graze nearby.
