One of the Observatory's core values is Safety and good health is a prerequisite to spending time on Maunakea. Please familiarize yourself with the high altitude health information and consult your personal physician with any issues or concerns.
Tours are scheduled in advance to accommodate our operations and research priorities. We recommend that your visit is the day before or 48 hours after an observing run and not during, since it is an all day event. Visitors must be prepared for last minute cancellations due to hazardous weather conditions or other emergencies.
The interior of the telescope domes are kept chilled to match the evening ambient temperatures near freezing. It is important to dress appropriately with layers, long pants, covered low heel shoes, heavy coat, UV filtering sunglasses and sunscreen.
Observers must supply their own four-wheel drive vehicle (4WD) to transport themselves to the observatory. Most rental car companies restrict driving on the Maunakea Access dirt road. Harper Car & Truck Rental allows driving on these roads. See Transportation for more information.
