Overview of Kaumana Caves

Kaumana Caves are part of a lava tube system formed by the 1881 eruption of Mauna Loa. Lava tubes are natural tunnels created when the surface of a lava flow solidifies while molten lava continues to flow beneath it. This unique geological feature offers visitors an up-close look at the fascinating processes that shape Hawaii’s volcanic landscape. The caves are a free, self-guided experience and are a popular stop for both locals and visitors.

Key Features of Kaumana Caves

1. Lava Tube Exploration

• Formation History:
  • The lava tube at Kaumana Caves was created by Mauna Loa's 1881 eruption. Legend has it that Princess Ruth Keʻelikōlani prayed to Pele, the Hawaiian goddess of volcanoes, to spare Hilo, causing the lava to stop short of the town.
• Two Main Entrances:
  • A set of stairs leads down into the collapsed section of the lava tube. Visitors can explore both the upper (mauka) and lower (makai) sections of the tube, which extend in opposite directions.

2. Unique Geological Features

Lava Formations:

• Inside the caves, you'll see fascinating geological features such as lava stalactites, smooth and rippled walls, and areas where lava solidified mid-flow.

Natural Skylights:

• Portions of the tube have collapsed, creating skylights that allow sunlight to illuminate the caves, creating a dramatic and beautiful effect.

Vegetation Growth:

3. Adventurous Experience

Rugged Terrain:

• The cave floor is uneven and rocky, offering an adventurous experience for those who enjoy exploring natural landscapes. Visitors are encouraged to bring flashlights and wear sturdy shoes.
