The skies over Chile’s Atacama Desert are blessed with over 300 clear nights per year, ideal for stargazing. These clear skies mean that this part of the country has become one of the world’s principal sites for astronomic observatories. Chile is now a major astrotourism destination.

Best places for stargazing

The towns in the altiplano in the Atacama Desert are the best place for star gazers to literally get their fill of the star filled sky. Towards the coast there is a higher chance of cloud cover, so inland at altitude, you are almost guaranteed clear skies. The smaller the town , the less the light pollution, and the more spectacular the panorama.

This is a year round activity. There is a greater chance of cloudy skies in the austral summer, December through March.

Beware of the full moon as the light it generates will “blot out” the majority of stars. The best time is with a new moon. Plan your visit according to the phases of the moon and to do so there are many online moon calendars.

 

Elqui Valley: The valley is just north of La Serena and the principal town is Vicuña. There are plenty of small and quaint places to stay and the place has a certain reputation for being mystical. The scenery is incredible and it is one of the principal producers of Chile’s national spirit Pisco, a grape brandy.

San Pedro de Atacama: This is the prime destination in the Atacama Desert. Nearby you will find salt flats where flamingos breed, geyser fields and pre-Columbian archaeological sites. Other attractions include incredible valleys with multicoloured rock formations, altiplanic lakes and much wildlife.

The night skies are a major attraction and you will find the options of several star gazing guided tours.

Putre: Inland from Arica and high up in the Altiplano is this off the beaten path town. Small and charming, it is within easy access of Lake Chungara (over 4,500 metres above sea level) in the Lauca National Park.

Visiting observatories

It is possible to visit some of the principal astronomical observatories which have sprung up in Chile after massive investment by many multinational agencies. However, if you wish to see the stars, a research astronomical  observatory is not the place to do so. Tours are arranged during the day leaving astronomers undisturbed and able to focus on their scientific research. They do offer a fascinating glimpse into the industry and the vast scale of its infrastructure.

The European Southern Observatory offers daytime weekend tours, which are free of charge and accompanied by an English speaking guide. These have to be booked in advance.  The following ESO observatories can be visited.
