Mauna Loa

Mauna Loa stretches across 5,100 square kilometers and rises 4,169 meters (13,678 feet) above sea level, forming half of Hawaii Island's total landmass. The volcano's gently sloping sides run through multiple climate zones, from tropical rainforests to barren alpine deserts near the summit.

The volcano has produced 34 documented eruptions since 1843, with the most recent in 2022 after a 38-year quiet period. Earlier eruptions threatened nearby settlements multiple times with lava flows that moved slowly downhill over weeks.

Hawaiian families consider the volcano the home of Pele, the goddess who rules fire and molten rock. During eruptions, some locals leave small offerings near lava flows to honor their connection to the land.

Visitors can reach the summit area through the Mauna Loa Observatory Road, which requires a four-wheel-drive vehicle and preparation for high altitude conditions. The air becomes thin above 3,000 meters (10,000 feet), so travelers should ascend slowly and watch for headaches or dizziness.

The weight of this massive structure causes the Pacific Ocean floor to bend downward several kilometers beneath its base. Measured from the seafloor to the summit, the mountain's true height exceeds Mount Everest.
