Stargazing in Atacama, Chile

The Atacama Desert is arguably the finest stargazing location on Earth. Sitting at 2,400m in one of the driest places in the world, it regularly achieves Bortle 1 conditions — the sky is so dark that the zodiacal light, gegenschein, and zodiacal band are routinely visible. The area hosts ALMA, Paranal (VLT), and the forthcoming ELT (Extremely Large Telescope). Over 330 clear nights per year and sub-arcsecond seeing make this the gold standard for visual and astrophotographic observation. San Pedro de Atacama offers tourist stargazing tours nightly.
