Additional Tips

Best Time to Visit: The best time for astronomical tourism in northern Chile is during the dry season (April to October), when the skies are clearer and the nights are cooler. The new moon phase is also ideal for stargazing, as there’s minimal light interference.

Altitude: Many of the observatories and stargazing locations are at high altitudes (over 4,000 meters), so be prepared for altitude sickness. Drink plenty of water, avoid strenuous activities on the first day, and allow your body to acclimatize.

Clothing: The desert can be extremely hot during the day and very cold at night. Be sure to pack layers, sunscreen, sunglasses and a good jacket for the evenings.

This itinerary offers an in-depth exploration of northern Chile’s natural wonders and its world-class astronomical tourism opportunities, including some of the most famous observatories and stargazing locations on the planet. It’s an unforgettable experience for anyone fascinated by the cosmos!
