Swimming season at Akçakoca (Düzce)

Since it's on the Black Sea coast, the sea can get choppy at times; water visibility is around 2-4 meters, so Mediterranean/Aegean-level clarity shouldn't be expected, though it's enough for swimming. Because the Black Sea's salinity is roughly half that of the Mediterranean, it's said to generally cause less irritation for sensitive skin. Along the 35-kilometer coastline, rare black-pearl-grained beaches (like Ceneviz Kalesi Beach) stand out.

When to go Summer months; beaches within coves are generally less choppy than open beaches.
Who it suits For those curious about the Black Sea's cool, distinctly different character; not for those expecting crystal clarity.
