Visiting the Mauna Kea Summit and Observatories gives you the feeling of being on top of the world for good reason: You’re actually pretty close.

The Mauna Kea Observatories (MKO) feature some of the world's largest telescopes, including equipment from Canada, France, and the University of Hawaii, due to its designation as an unparalleled destination for stargazing.

Top tier experience
Our tour guide John was great- he shared some wonderful photos. It was great to be able to reach the summit and see all twelve telescopes. The two stops along the way to acclimate to the elevation were very helpful
