Neptune Caves

The cave network features natural limestone formations along the Eau Noire river, creating passages that visitors explore through guided walking tours and boat rides.

The Eau Noire river shaped these underground cavities over 300 million years, forming one of Belgium's earliest documented cave systems through limestone erosion.

Multiple language tours in French, Dutch, German, and English connect visitors with local geological heritage while explaining the formation processes of stalactites and stalagmites.

The cave maintains a constant temperature of 12 degrees Celsius throughout the year, requiring visitors to bring warm clothing regardless of external weather conditions.

Visitors can navigate sections of the cave system using packrafts with headlamps, offering an alternative perspective of the underground waterways and rock formations.
