Grottes de Pethoen, Natural cave in Médu, New Caledonia.
Pethoen Cave contains a large freshwater pool beneath numerous limestone stalactites that form a mineral curtain within the rocky chamber.
The cave structure developed through geological processes on Maré Island, resulting from the gradual uplift of ancient coral reefs.
The Médu tribe maintains strong connections to this cave, which serves as a natural swimming spot and gathering place for local residents.
Located fifty meters from the main road, visitors can reach the cave through a forest path hidden before the first houses of Médu.
Water droplets falling from stalactites create shifting light patterns on the surface of the clear underground pool.
