Maui's Volcanic Wonders

Maui’s landscape is defined by two primary volcanic masses: the massive Haleakalā shield volcano and the older, deeply eroded West Maui Mountains, or Mauna Kahālāwai. This list explores the island's geological evolution, from the 10,023-foot summit of Haleakalā Crater to coastal cinder cones like Puʻu Olaʻi. These sites showcase unique features including high-altitude peat bogs, ancient rift zones, and colorful mineral deposits formed by eruptions and erosion over nearly two million years.

Haleakala Crater

Haleakalā, or the East Maui Volcano, is a massive, active shield volcano that forms more than 75% of the Hawaiian Island of Maui.
