Climbing in Sajama national park would not even be half as enjoyable without the relaxing thermal waters. While sitting in a 40°C+ warm water you can enjoy the view on Sajama 6548m, the twins Parinakhota 6330m & Pomerape 6280m  and Acotango in the distance.

 

Further up in the Valley are boiling water pools colored by the specialized micro organism living in this extreme environment.
