Significant sunset snarl happening atop Mauna Kea
Sunset is an epic time of day on the Big Island for residents and visitors alike as the sun sinks in the western horizon over the vast Pacific Ocean, creating breathtaking scenes of orange, yellow and sometimes red that fade to dark blue and purple as the first stars appear then finally black with the entire cosmos overhead.

There are probably two “zones” to get the best views: any beach, park or coastal spot on the island’s west side and — perhaps the more coveted of the two because of its lack of light pollution and most often amazingly clear skies — above the clouds atop Mauna Kea.
Mauna Kea has apparently become even more of a popular place as of late to check out sunset, and it’s causing some traffic congestion issues.
University of Hawai‘i at Hilo, which oversees the Center for Maunakea Stewardship, reports that traffic on Mauna Kea Access Road, at Onizuka Center for International Astronomy Visitor Information Station and in the summit area has become significantly heavier than usual during sunset hours, particularly on weekends and holidays.
Even larger crowds and heavier traffic can be expected when there is snowfall on the mountain.
To help manage the summit snarl and protect people, as well as Mauna Kea’s delicate ecosystem and cultural sites, those who are making the trek up the mauna are urged to:
- Plan ahead and allow extra time for travel.
- Carpool whenever possible.
- Arrive early to secure parking.
- Follow all parking guidelines.
Parking is only allowed in designated areas at the summit and the Visitor Information Center. Parking outside designated areas is strictly prohibited.
Visitors are also advised to follow the guidance of Mauna Kea rangers, who are on-site to manage traffic flow, ensure safety, assist visitors and protect natural and cultural resources.
Weather conditions on Mauna Kea can change suddenly, too, bringing freezing temperatures, strong winds, snow and icy roads.
Be sure to check the latest weather conditions, road status and forecast on the Center for Maunakea Stewardship website before making the summit ascent.
