Best for intermediate divers, shore entry, strong current.
Le Sec des Chardons is a combined reef and wreck site located off the coast of Brittany and Normandy. This shore-entry dive is suited for intermediate divers due to the strong currents that define the area. Divers should plan their entry around slack water to manage these demanding conditions. The site is characterised by cold water temperatures and variable visibility, requiring the use of a drysuit or thick wetsuit. Boat traffic is a consistent hazard, making the use of a surface marker buoy essential for all ascents. Always confirm local tidal information and current conditions before entering the water.
