The Basics

Mauna Kea tours depart from Hilo, Kona, and Waikoloa Village, and usually last upwards of eight hours. Whether you choose to visit for sunrise, sunset, a midday summit tour, or after-dark stargazing, the mountain makes for a popular day trip on the Big Island.

The Mauna Kea Visitor Information Station sits at 9,300 feet (2,790 m) and features interactive displays and videos, with telescopes, talks, and tours. It’s important to stop here even if you’re headed to the summit to acclimate to the altitude. In addition to checking out the magnificent night sky, you can learn about Mauna Kea’s formation and why the mountain is considered sacred to native Hawaiians.

Best Mauna Kea Summit Tour (Free sunset and star photo!)
Tour guide was knowledgeable and courteous. Van was comfortable and safe. Veggie and BLT sandwiches were good. Great experience viewing summit at sunset and viewing stars after sunset. Warm jackets provided. Photos taken by guide turned out great. The best option tour of Mauna Kea Summit if you are staying in Hilo. Met tour van at Gilbert Kahele Recreation Park. Excellent parking and clean restroom facility.

Hunter and Heather were great guides and worked hard to accommodate everyone. The stars were amazing. Plenty of snacks and well planned excursion. But please clean the bus windows as the views are everything and the windows were filthy!

I loved learning about the stars. This was an outstanding trip. Even though it was a thoroughly great experience, it didn't feel COVID-safe. There were 9 people on our bus which didn't allow for any distancing. We were enclosed for an 30-60 minutes at a time. Masks were required, but this was a lot of close exposure. As long as you're ok with that, this is a phenomenal trip.

Our guide was Hunter who did an amazing job! He was very friendly, laid back and very knowledgeable about the history of Mauna Kea, the various observatories and astronomy in general. We would highly recommend this tour to anyone looking to have a once in a lifetime experience and see a different side of Hawaii!

What Makes Mauna Kea Ideal for Astronomical Sightseeing?

The Subaru Telescope, the W.M. Keck Observatory, and the NASA Infrared Telescope Facility take advantage of Mauna Kea’s ideal location near the equator and above most of the atmosphere’s water vapor, which means a clear view of stars in both of the earth’s hemispheres.

Best Ways to Summit Mauna Kea

You can make an ambitious go of the summit on your own (on foot or in a vehicle), or join an organized summit adventure tour during visiting hours (from 30 minutes before sunrise to 30 minutes after sunset). From the Visitor Information Station, a roughly 10-hour, roundtrip hike on a rugged trail takes you to the top and back. Be prepared for a workout, and be sure to wear layers and sturdy closed-toe walking shoes; you’ll encounter all kinds of weather as you ascend above the Big Island’s layer of cloud cover. You must bring your own water and pack out your waste; there are no amenities on the trail.

If you’d rather drive to the top, you’ll need a 4-wheel drive vehicle, plenty of water and sunscreen, and a keen eye for hazards. Depending on conditions, summit attempts can be particularly dangerous in winter. Mauna Kea is one of the only places in the world where you can drive from sea level to nearly 14,000 feet in a few hours.
