This dive site, Vaumarcus, is an old gravel quarry located on Lake Neuchâtel. The unique underwater landscape was formed by the exploitation of gravel, leaving behind a distinctive relief reminiscent of the Pyramids of Euseigne. Divers can explore these pyramid-like formations, which are separated by small canyons. The north side of the site features a steep slope that quickly descends beyond 40 meters. It's important to note that the pyramids can be unstable, requiring careful navigation and excellent buoyancy control.
The waters of Vaumarcus are home to various freshwater species, including pike, perch, and crayfish. Additionally, the invasive Quagga mussel, originally from the Black Sea, has colonized Lake Neuchâtel and can be observed here, contributing to the unique ecosystem.
While specific seasonal highlights are not provided for Vaumarcus, temperate months typically offer better diving conditions in Swiss lakes. Divers should be mindful of the cold water, especially at deeper sections, and the potential instability of the pyramid structures. Freedivers will find suitable depths and interesting topography for exploration, particularly along the steep slopes and around the canyons.
