Stargazing in Mendoza, Argentina

Mendoza, at the foot of the Andes in western Argentina, combines a dry, sunny climate with quick access to high-altitude dark skies. The Bortle 7 city sits in wine country, but the Andean foothills and the high passes toward Chile reach Bortle 2–3 within a couple of hours, with exceptional transparency at altitude. At 32.9°S, the southern sky is superbly placed: the galactic core stands high overhead in winter, and the Magellanic Clouds and Southern Cross are brilliant from a dark site. Mendoza's reliably clear, dry nights and the dramatic Andean backdrop make it a rewarding base for stargazing.
