The skies of northern Chile are known around the world for their sharpness and clarity, thanks to the fact that it only rains about 60 nights a year. In the Atacama altiplano and the Andean area of Coquimbo, the skies offer some truly excellent stargazing. And it's not only scientists who come from all over the globe to enjoy the cosmos at immense observatories like Paranal. Travelers also can take advantage of centers for astronomy tourism.

Located east of San Pedro de Atacama at an altitude of 2,600 meters, Paranal is the largest and most important astronomy center from a scientific perspective. You can visit it during the last two weekends of every month except December.

The oldest center in the Southern Hemisphere is the Cerro Tololo Observatory, 87 km from La Serena in the heart of the Elqui Valley. If you'd like to see its eight telescopes, you have to make reservations in advance. Guided visits are held by day so that you can enjoy the local scenery as well.

The Elqui Valley is also home to the Mamalluca Observatory. While its telescopes are smaller, they still allow you to observe galaxies, nebulae and constellations. It's perfect for tourists because it offers presentations on the cosmos and is easy to visit, with guided visits every night and the possibility of same-day reservations during some months of the year

The Cruz del Sur Observatory of Combarbalá in the Limarí Valley features four observation domes that can be connected to cameras, an amphitheater, and specialized tours. Perfect for astronomy enthusiasts.
