4:14 PM LOCAL TIMEMauna Loa is a colossal shield volcano and one of the most important natural landmarks of Hawai'i. Rising over 13,681 feet (4,170 meters) above sea level but descending deeply to near -33,500 feet (−10,210 meters) when measured from its summit to the ocean floor, it spans much of the Big Island; its vast bulk shapes regional climates and weather. The volcano features wide, gentle slopes that host popular trailheads, to more remote high-elevation craters, and extensive lava plains from historic eruptions. Visitors typically access the volcano via Hawaii Route 11, stopping at visitor centers, trailheads, and lookout points; activities include high-elevation hikes, mountain camping (where permitted), and observing volcanic landforms. Active and monitored, Mauna Loa offers a rare direct connection to planetary volcanic processes and natural hazard awareness.
