About this dive site

This dive site is located at the Les carrières de molasse, an area characterized by extensive limestone quarries. These quarries offer a unique underwater landscape created by ancient sedimentary rock formations. The dives here are often conducted within these large, open spaces, providing a striking contrast between the natural environment and the human-made structures. Visibility can vary significantly depending on weather conditions and water clarity. The quarries present interesting photographic opportunities due to their scale and unusual shapes. It’s important to note that currents can be strong in certain areas of the quarries, potentially making navigation challenging for less experienced divers. The area provides a compelling dive experience with its distinctive geological features.
