Almost a mile further north you can already see the first caves, including the Grotta di Pozzo Vivo and the Grotta dei Colombi, a natural cavity characterized by a hole in the rock, through which the sunlight penetrates and illuminates the cave and its clear waters.
Sailing further north you will be able to see from the sea the small natural port inhabited by fishermen, called Porta Alga, with its picturesque white houses and the trulli placed at the top.
