What strikes the visitor who arrives to Rurutu are the high grey jalouses perfores of numerous caves. Quite vast. As from it emerged the ancient coral reefs suffer the intense erosion of tropical rains loaded with gases of organic origin.

These acid waters have infiltrated, enlarging the little creaks where numerous forms of calcite concretions have been formed, stalactites and stalagmites. If certain caves are visible with no problem and easy access, there are others well hidden and only a guide could experiment to discover. We should realize therefore, the reticence to have this cavities discovered, since some of them have been wreck after disrespectful trespassing by beauty visitors and of underground patrimony of Rurutu. The speleologist at Rurutu find the land virgin but also a very difficult progression in the richest areas in the dangerous makateel at the calcarious needles areas.
