W. M. Keck Observatory Headquarters is at 65-1120 Mamalahoa Highway in Waimea, on Hawaiʻi Island. Its exhibits introduce the astronomy carried out with the twin Keck telescopes on Maunakea, including telescope models and materials used in their mirrors. Staff-led tours share information about current and future projects. The high-altitude observatory site also gives you a chance to look across the mountain landscape; the drive is more comfortable in a 4x4 vehicle, and temperatures can drop even in May.
