Entrance to the lava tube.

The cave is located on the island of Hawaiʻi near the city of Hilo.

A collapsed skylight^[3] provides easy access to two of the tube's entrances which became a tourist attraction. Some parts of the tube are located under private property,^[4] and so are some of the entrances.

Many natural features, such as the stalagmites and the stalactites have since been broken off by tourists as souvenirs.
