description Kaumana Caves Overview
Kaumana Caves is a publicly accessible section of a lava-tube system near Hilo on the island of Hawaii. The tubes formed during Mauna Loa's 1881 eruption, whose lava flow approached the town. Visitors enter through a collapsed skylight using a concrete stairway, but exploration beyond the entrance involves uneven volcanic rock, darkness, low ceilings, and no installed lighting, so sturdy footwear and personal lights are appropriate.

How were the Kaumana Caves formed?
The Kaumana Caves are a massive lava-tube system that formed during the Mauna Loa eruption of 1881 on the island of Hawaii. The flowing lava cooled on the outside while the hot magma continued to move, leaving hollow tunnels behind.
Where are the Kaumana Caves located?
This publicly accessible cave system is located just outside the town of Hilo on the Big Island of Hawaii. The main entrance is situated right off Kaumana Drive.
How do you enter the Kaumana Caves?
Visitors enter the subterranean tubes through a naturally collapsed skylight in the ancient lava rock. A concrete stairway has been installed to help people safely climb down into the main tunnel opening.
Do you need special gear to explore the Kaumana Caves?
Beyond the lighted entrance area, exploration requires strong flashlights or headlamps, as the cave is pitch black. Visitors are also advised to wear sturdy shoes due to the incredibly rough, uneven volcanic rock.
