Dive-site story
Located off the Biokovo coastline near Drašnice, this site centers on a submarine freshwater spring known locally as a vrulja. Subterranean runoff from the limestone massif discharges directly into the sea, producing visible shimmering haloclines and pronounced thermoclines where icy mountain water collides with the Adriatic. The seabed transitions from shallow gravel into stepped limestone drop-offs riddled with crevices and small fissures.
