Mauna Kea

From beach to snow in one drive — the world's tallest mountain base-to-summit. Altitude, not distance, is the challenge; acclimatize at the visitor station.

Summit temperature is estimated from the Hilo forecast using the −6.5°C/1,000 m lapse rate. Expect much stronger wind and lower visibility on the tops, and treat the freezing level as a guide rather than a measurement.
