Guided summit tours include sunset viewing above the clouds, stops at the Onizuka Center for International Astronomy, and access to the summit road that requires specialized 4WD vehicles. Tours depart from Kona, Waikoloa, and Kohala areas. No Hilo departures are currently available.

Who should not travel to the summit?

The summit area is safe for healthy adults, though some may experience altitude sickness. Due to high altitude and low oxygen levels, the following visitors should not travel beyond the visitor center: pregnant women, children under 16, those with respiratory or heart conditions, individuals with high blood pressure, persons with a BMI above 40, and anyone who has been scuba diving within the past 24 hours.

When is the best time for stargazing on Mauna Kea?

The best stargazing conditions occur on clear, moonless nights. Check a lunar calendar when selecting a tour date to maximize visibility of the Milky Way, planets, and deep-sky objects.
