See Visiting Maunakea Safely and Responsibly for important safety information. Due to the hazards of altitude sickness, pregnant women, persons in poor health, and children under 13 should not venture above the Visitor Information Station. Drivers are required to use 4-wheel drive vehicles above the VIS because the road to the summit is unpaved, rough, and quite steep. Those traveling to the summit should always use 4WD Low Range to reduce brake failure and overheating. Make sure your vehicle and any items taken to Maunakea are clean to prevent the spread of invasive species.
