The morning chill of the Atacama Desert is beaten with the heat of the El Tatio Geysers located around San Pedro and overlooked by the Andean mountains. The site is great to observe at dawn when its 80 vents emit massive pillars of steam, which gradually disappear with the sunrise. The geysers form a network of hot streams, swimming pools, and mud baths which means that tourists may not only delight in the spectacular picture but also enjoy a warm bath. Besides El Tatio Geysers, there are the less popular Puritama Hot Springs (Termas de Puritama) also located around San Pedro. The Atacama Desert is best visited between September and March.
