Perched atop Mount John near Lake Tekapō in the Mackenzie Basin, Mount John Observatory is one of the best stargazing locations in the world. Situated at an altitude of 1,029 meters, the observatory benefits from the region's clear skies, minimal light pollution, and dry climate, making it an ideal place for astronomical research and public tours.

Established in 1965, the observatory is operated by the University of Canterbury and plays a crucial role in scientific study. Its telescopes, including the powerful 1.8-meter MOA (Microlensing Observations in Astrophysics), help researchers observe stars, planets, and distant galaxies.

Visitors can embark on guided night sky tours through Earth & Sky, where professional astronomers guide you through celestial wonders such as constellations, planets, and the Milky Way. The observatory is also part of the Aoraki Mackenzie International Dark Sky Reserve, a UNESCO-recognized area that protects its pristine stargazing conditions.

By day, Mount John offers breathtaking views of Lake Tekapō, snow-capped mountains, and the surrounding plains, making it a must-visit for both astronomy enthusiasts and nature lovers.
