Freshwater chalk quarry at Lac bleu with clear blue water, club-managed access, and a calm low-current setup. Divers come for the stepped shore entry, a rocky wall, a small wreck and freshwater life such as perch, pike, carp, roach and crayfish. Plan around fixed sessions and the summer closure, and keep a light finning style because the chalk bottom can cloud the water quickly.
