Kaumana Caves State Park

Tucked into the hillside just outside Hilo, Kaumana Caves State Park provides a window into the Big Island’s volcanic history. Formed by a Mauna Loa lava flow in 1881, the cave system remains raw and untouched, with mossy skylights filtering light and cooled lava formations creating an otherworldly landscape. Unlike the more frequented Thurston Lava Tube in Volcanoes National Park, Kaumana Caves offers a less crowded, more rugged experience. Visitors can explore at their own pace, navigating the natural tunnels and marveling at the unique geological features that surround them.
