Introduction

Mauna Kea is a dormant volcano on Hawaii's Big Island, ~4,207 m (13,796 ft) above sea level — Hawaii's highest peak and the world's tallest mountain measured from its oceanic base (~10,203 m). Its summit hosts the world's densest cluster of astronomical telescopes, world-renowned stargazing conditions and spectacular alpine sunsets — one of the Big Island's most scientifically fascinating and naturally dramatic attractions. The summit is one of Earth's best astronomical sites — its extreme altitude, minimal light pollution and dry, stable atmosphere draw 13 telescopes from 13 countries. The Visitor Information Station (~2,800 m) offers free astronomy exhibits and evening stargazing programs. The road to the summit requires 4WD; the landscape shifts from tropical vegetation to barren alpine desert. On clear days, summit views are spectacular with clouds below and dramatic sunsets. Note: the ~4,200 m summit carries altitude sickness risk; acclimate at the visitor station first. Visiting Mauna Kea and gazing at the pristine night sky from this world-class observatory is a unique Big Island science and nature experience.
