Geisers of Tatio is located at 95 kms. northeast of San Pedro de Atacama at an altitude of over 4000 meters above sea level. It is one of the most exciting and interesting places to see in Chile. It is a geothermal field caused by the proximity of the El Tatio Volcano and in which an underground river runs and helps to produce the boiling phenomenon. The steam usually rises up to about 10 meters from a boiling-water pool. We must be very careful when walking through this area. The best time to visit these pools, is precisely at dawn (06.00 AM), when the sun begins to warm the icy morning. It is also possible to take a swim. Around the geisers there are several hot spring pools.
