The Neptune Caves: a place of relaxation and discovery located in an exceptional setting.

Located in the heart of the “Calestienne”, the site of the Neptune Caves offers you a unique and unspoiled natural setting.

Explore the caves to discover a fascinating underground world hidden in the depths of a rock aged hundreds of millions years,  or wander on our trails in search of the typical species of this protected area belonging to the Natura 2000 network.

Do you prefer relaxing while admiring the spectacular landscape? We welcome you under our covered terrace to enjoy an ice cream chosen among a wide selection, or to savour a local drink at your leisure.

Are you here for holiday or for a relaxing day? Your children will have the opportunity to climb and have fun in our brand new wooden playground.
