What Travellers Say
Reviews Summary
Visitors are captivated by the unique underwater ruins of Baia and the historical significance of Castello di Baia, offering stunning views. While the journey and some aspects of Naples can be gritty, the archaeological discoveries and the authentic Italian experience are highly rewarding.
"Nice place charming beach. It is not very well marked on google. It toom us some time to get there and find it. You have to take a small boat that comes every 10 min to pick up people. You pay on arrival, although they wrote 35 euros they took 50 for 2 people, 1 umbrella and 2 chairs.
There is also a place to eat.
Nice experience in general:)"
