Sea in Naples: Guide to Beaches, Facilities, and Swimming Areas
When you think of Naples, you think of pizza, chaos, and history. But Naples is also a seaside city, overlooking one of the most beautiful bays in the world. During theholidays in Naples, many tourists do not consider the idea of swimming in the city, thinking that the sea is polluted or unreachable. In reality, there are free beaches, equipped facilities, and protected marine areas where the water is clean and swimming is safe. This guide shows you where to go, what to avoid, and how to enjoy the sea of Naples without straying too far from the city.
Swimmability in Naples: Myths and Realities
The problem of urban beaches
The beaches closest to the center (Mergellina, Rotonda Diaz, Santa Lucia) have historically been discouraged for swimming due to sewage discharges and poor water circulation. The ARPAC (Regional Agency for Environmental Protection of Campania) data updated to 2025 indicates thatmany sections of the central waterfront are not suitable for swimming.Swimming in these areas is prohibited and dangerous for health.
Where the water is clean
The good news is that just a few kilometers from the center – or even within the city in some areas – there are beaches with clear and certified water. The best areas are:
Gaiola(Posillipo): protected marine area, excellent water
Monache Beach(Posillipo): small cove, safe bathing
Gaiola Underwater Park:diving spot, but also for swimming
Lake Averno(Pozzuoli, but easily reachable)
Bagnoli Beaches:undergoing redevelopment, some open
