Why Stargazing in Aoraki/Mount Cook is Unique
Aoraki / Mount Cook National Park is one of the most remarkable places in New Zealand to experience the night sky. Located within the Aoraki Mackenzie International Dark Sky Reserve, the region benefits from exceptionally low levels of light pollution, crisp alpine air and vast open skies. Join us on the only stargazing tour in the Aoraki/Mount Cook National Park.
Surrounded by New Zealand's highest mountains, Big Sky Stargazing offers a unique perspective on the cosmos. On a clear night, the Milky Way stretches overhead in extraordinary detail, while distant galaxies, star clusters and planets become visible through our powerful telescopes. Our resident astronomy guides will take you on a 90-minute tour of the night sky through high powered telescopes along with discussing incredible features visible to the naked eye.
Unlike many urban stargazing experiences, the night sky in Aoraki / Mount Cook remains largely untouched by artificial light, creating ideal conditions for astronomy and astrophotography throughout the year.
