Grotte de Hnanawae

The Hnanawae Cave extends 11,410 meters beneath the surface, featuring an intricate network of chambers connected through three main sections at 20 meters depth.

French speleologists conducted the first scientific exploration in 1995, documenting the cave's formation process that began 125,000 years ago through seawater interactions.

Melanesian people utilized the cave entrance area for shelter during tribal conflicts and water collection, leaving behind cave paintings, fire sites, and skeletal remains.

The cave entrance lies 4.7 kilometers south of Wedrumel at 95 meters above sea level, accessed through a five-meter-deep sinkhole.

The eastern network contains geological formations including stalactites, stalagmites, sinter basins, and tubular formations functioning as a natural museum.
