Recommendations for the best experience:
A 4x4 vehicle is required to drive from the visitor's center to the summit.
Go on a moonless night for the best stargazing. The moon’s brightness can wash out the night sky and make stars appear less vivid.
Arrive at the Visitor Center in early afternoon. You’ll need to stop and acclimate for 30 minutes before continuing to the summit. If you’re pregnant or traveling with children under 12, it’s not recommended to go beyond this point. Instead, enjoy the sunset from Puʻu Kalepeamoa, a nearby lower peak with stunning views: Viewpoint location
Visit Lake Waiau on the way up to the summit. Park at the Lake Waiau parking lot: Parking location, Then take the medium hike to Lake Waiau, one of the highest lakes in the U.S. and a sacred site in Hawaiian culture: Lake Waiau trail
Plan to leave the summit before sunset. Rangers close the summit area at sundown. Head back down about 45 minutes before sunset and catch the view from Puʻu Kalepeamoa instead. Viewpoint location
Want a photo with the Milky Way? Book a stargazing session with our favorite local astronomer, who provides warm jackets and includes a free photo of you under the stars: Book with Epic Big Island
Don’t Have a 4×4 Vehicle? Book a Guided Tour Instead:
Mauna Kea Summit Adventures – best for comprehensive excursions with top-tier guides and stellar reviews.
Hawaii Forest & Trail – ideal for smaller groups and a deeper connection to culture and land.
Volcano Tours – perfect if you want to focus on astronomy with fewer distractions.
The Maunakea Visitor Information Station, also known as the Onizuka Center for International Astronomy, is a must-visit spot for stargazing enthusiasts and nature lovers alike. Located at 9,200 feet elevation on the Maunakea Access Road, this center offers daily hours from 9:00 a.m. to 9:00 p.m. Visitors can enjoy short hiking routes, browse through the First Light Store for souvenirs, and even catch a glimpse of the breathtaking Maunakea summit. Remember to drive a 4-wheel drive vehicle above the station and stay safe while exploring this unique and awe-inspiring destination!
TRAVEL TIPS:
Weather: Temperatures at the summit can drop below freezing, especially after sunset. Winds are strong, and clouds can roll in quickly—so dress warmly and consider booking an earlier tour to avoid afternoon overcast conditions.
What to Wear: Sturdy, closed-toe walking or hiking shoes are essential. Dress in layers, and bring a warm jacket, hat, and gloves—even in summer.
What to Bring: A small backpack, water, sunglasses, snacks, and an extra warm layer. An umbrella can help if you’re staying at the mid-elevation Visitor Center, but it’s often too windy at the summit.
Phone Service: Expect limited to no service once you leave Saddle Road and ascend Mauna Kea—especially near the summit and on hiking trails.
Bathrooms: Portable toilets are available at the Visitor Information Station (~9,200 ft). There are no restrooms at the summit.
Parking: There’s limited gravel parking at the summit and at Lake Waiau trailhead. Always lock your vehicle and hide valuables—especially if parking at lower elevations or during sunset viewing.
Check-In (if on a guided tour): Your guide will meet you at the Visitor Center or designated pickup point. Most tours include walking sticks, jackets, and snacks. Waivers may be required.
Photography: Cameras are welcome for personal, non-commercial use. Mauna Kea’s summit and Lake Waiau offer otherworldly photo opportunities—but stay on trail and respect sacred areas.
Accessibility: Due to steep, rocky terrain and high elevation, the summit and trails are not handicap accessible. Those with mobility or respiratory concerns should consult with a doctor before visiting.
Mauna Kea Summit – History, Culture, and Significance
1. The Highest Point in Hawaiʻi
Mauna Kea is the tallest mountain in Hawaiʻi, rising 13,803 feet (4,207 meters) above sea level—and more than 33,500 feet from its base on the seafloor, making it the tallest mountain in the world when measured from base to summit.
Its summit offers stunning panoramic views, stark alpine landscapes, and is home to some of the clearest skies on Earth, making it a premier location for astronomical observation.
2. Sacred to Native Hawaiians
To Native Hawaiians, Mauna Kea is a sacred mountain, known as Mauna a Wākea, or “Mountain of Wākea,” the sky father in Hawaiian cosmology. The summit is considered the piko (spiritual center) of the island—a place where heaven and earth meet.
It is home to:
Burial sites of ancestors
Sacred shrines and altars
Sites of ceremonial and spiritual practice
Because of its sacred status, Mauna Kea is treated as kapu (sacred, off-limits) in many contexts, especially its summit area.
3. Scientific Importance
Despite its cultural significance, the summit is also host to 13 telescopes operated by 11 countries, making it one of the world’s most important astronomical research sites. Its dry air, high elevation, and clear skies provide near-ideal conditions for observing space.
This dual identity—as a site of cutting-edge science and deep spiritual reverence—has led to ongoing controversy and public discourse about land use, stewardship, and cultural sovereignty.
4. The TMT Controversy
In recent years, Mauna Kea has been at the center of a major cultural and political movement due to opposition to the proposed Thirty Meter Telescope (TMT). Many Native Hawaiians and allies oppose further development on the summit, citing:
Desecration of sacred land
Historical marginalization of Indigenous rights
Environmental and cultural degradation
In 2019, peaceful protectors (kiai) held space at the base of Mauna Kea in a major movement that gained global attention, highlighting the call for cultural respect, environmental protection, and Indigenous sovereignty.
5. Visiting the Summit
Visitors can reach the summit via a steep, unpaved 4WD road, though access is restricted at times for weather, safety, or cultural reasons. A stop at the Onizuka Center for International Astronomy (at ~9,200 ft) is highly recommended for acclimating to altitude.
Important guidelines for visiting:
Show deep cultural respect
Do not remove rocks, build cairns, or disturb natural features
Dress warmly (temperatures can drop below freezing)
Avoid summit visits if you have health conditions or are pregnant
