Relax in the warm waters of these natural pools, surrounded by lush vegetation at the base of the Machu Picchu mountain. These pools, which give the town of Aguas Calientes its name, were formed due to the volcanic activity of the region. Soak in the comfortable waters, with temperatures that range from 100°F to 114°F. But don’t worry about the water’s slight yellow tinge—it’s caused by sulfur, iron and other minerals that are naturally present.

Many tours include a visit to Aguas Calientes as part of the Machu Picchu experience, and there are changing rooms, showers and lockers available.
