Safety reminder: The summit of Maunakea at nearly 14,000-feet altitude, presents unique challenges to visitors. Visits to the summit require a 30 minute acclimatization stop at the 9,200-foot Onizuka Visitor’s Center, warm clothing for the summit, sunscreen for protection from excessive UV radiation, and water. A four-wheel-drive vehicle is required beyond the 9,200 foot level as the air is too thin to adequately cool a vehicle’s brakes upon descent.

The Mauna Kea Visitor Information Center , located at the 9,200-foot basecamp, and provides information about cultural, environmental, and geological features of Maunakea as well as information about the world-class astronomy it provides. After dark, there are free stargazing programs.

Temperatures on the summit can fall to 20 degrees Fahrenheit, or -4 degrees Celsius, within a matter of hours: it is highly recommended that all visitors to the summit take warm clothing and sturdy footgear sufficient to withstand the elements should the vehicle break down. High winds on the summit can often result in blowing snow, sleet, fog and sometimes, flying rocks. Winds can reach 150 mph.

The summit of Maunakea is one of the most remote locations in the Islands. Medical and auto help is a minimum of two hours away. Most car rental companies void the rental contract if their cars are driven on Saddle Road and to the summit. It is a safety requirement of the road-maintenance organization for the summit that all vehicles driving up and down the mountain beyond the Hale Pohaku basecamp be four-wheel-drive vehicles. Caution is advised.
