In the heart of an unspoiled natural setting, the NEPTUNE CAVES (Grottes de Neptune) offer you an educational and fun opportunity of discovery, with family and friends, come hell or high water!
Throughout a 45-MINUTES GUIDED TOUR, plunge into an extraordinary decor made up of wonderfully emphasised creations of nature.
Whether you are a child or an adult, underground enthusiasts or just simply looking for a unique experience, you will not fail to be enchanted by our boat trip along the underground river followed by a sound and light show!
After the visit, don’t miss a detour via our reception chalet where you can buy souvenirs, jewels and minerals but also cold drinks, beers from the region and ice creams.
Caution : due to the roadworks on the N5 (national network) in the suburbs of Frasnes-lez-Couvin, please follow the deviation signs “rue de l’Adujoir – Grottes de Neptune” to reach the caves.
