Kaumana Cave Big Island

This cave is actually a skylight in a 25-mile long lava tube that was created by an 1881 flow from Mauna Loa. Located near Hilo, the opening to the tube is overgrown with plants due to the abundant rain on this side of the island.Kaumana Cave Big Island

Long, thin roots reach all the way down to the floor of the lava tube. Kaumana Cave Big Island3

The opening is well-marked and a concrete staircase allows for easy entry to the cave.  Bring a flashlight if you plan to explore the 2-mile long opening in the tube.   Use caution when climbing the stairs as they may be slippery.

Use caution when climbing the stairs as they may be slippery. The cave entrance is well-marked and easily accessed via the stairs.4

History reports that the 1881 flow stopped within 1 1/2 miles of Hilo due to the intervention of Princess Ruth. She camped in front of the flowing lava and prayed to Pele to spare the city. Her prayers were answered!Kaumana Cave Hawaii - The Big Island
