The caves of Salento are natural wonders that are absolutely worth discovering. These extraordinary cavities, carved by the sea, are found along both the Ionian and Adriatic coasts and hold fascinating stories and mysterious legends. Nature has been incredibly generous here, giving us numerous caves, some deeper than others, mirrored in crystal-clear waters and creating extraordinary plays of light and reflections.
For this reason, if you are looking for a unique experience, the best option is to join one of the many boat excursions in Salento and allow yourself to be captivated by the beauty of the sea.
The Most Spectacular Caves of Salento
Salento boasts numerous caves, but some deserve special mention. Below is an overview of the most beautiful and evocative ones, set along the Adriatic and Ionian coasts.
Grotta della Poesia
Grotta della Poesia is a spectacular natural swimming pool located in Roca Vecchia, on the Adriatic coast, in the municipality of Melendugno. Its emerald-green waters, surrounded by golden rocks rising up to 5 metres high, create an enchanting landscape reminiscent of the Mexican cenotes.
It is a natural cavity formed by the gradual erosive action of water and is itself divided into two sections: Grotta della Poesia Grande and Grotta della Poesia Piccola. The two communicate through an underground passage and are only sixty metres apart, with a small beach located between them.
The cave is called Grotta della Poesia because, according to an ancient legend, a long time ago a young woman used to dive and bathe in this natural pool. She was so beautiful that she attracted the attention of many people, who would come to the site simply to admire her. Among them was a great poet of the time, who made her his muse and dedicated some of his works to her.
It is also important to mention the discovery of inscriptions of Greek, Latin and Messapian origin on the walls, which made it possible to understand that the cave was a place of worship dedicated to the god Taotor.
This cave is part of one of the most important archaeological sites in Italy and, in order to preserve its integrity, an entrance fee of approximately €3 has been introduced for visitors who are not residents of the province of Lecce.
Grotta dei Cervi
Continuing along the Adriatic coast, at Porto Badisco, we find Grotta dei Cervi, a site of great archaeological importance. The walls of the cave are decorated with numerous rock paintings made using bat guano and red ochre, forming one of the most important Neolithic pictorial complexes in Europe, dating from between 4,000 and 3,000 BC.
The figures depict hunters, animals (dogs, horses and deer), objects, magical symbols, abstract geometric shapes and numerous hunting scenes featuring deer, from which the cave takes its name.
One of the most famous pictograms is the so-called Dancing God, depicting a dancing shaman.
Access is restricted and reserved for researchers and journalists accompanied by qualified speleologists.
Grotta Azzurra
Located in Castro, Grotta Azzurra is one of the pearls of the Adriatic coast and can only be reached by sea.
To explore Grotta Azzurra, visitors can take a small boat or kayak from the surrounding beaches and make a short journey to the cave entrance. The cave is fairly spacious and offers enough room for boats.
As you slowly enter, the magic is revealed when the sun’s rays penetrate the water and illuminate the interior with an iridescent blue light.
The water inside the cave is exceptionally clear, allowing visitors to see the seabed and underwater rock formations with remarkable clarity.
Grotta Azzurra is not only a spectacular sight for visitors but also an important habitat for many marine species. The walls of the cave are covered with algae and corals, and its unique environment provides shelter and nourishment for numerous fish and other marine creatures. During your visit, you may be lucky enough to see colourful fish and other creatures swimming around the boats.
These characteristics are what make swimming in Grotta Azzurra such a unique experience.
Grotta della Zinzulusa
The legend of Grotta Zinzulusa, discovered in 1793 near Castro, tells the story of a cruel Baron of Castro who, despite his wealth, left his daughter dressed in rags and caused his wife to die of grief.
A kind fairy appeared to the little girl, gave her a beautiful dress, and the rags (zinzuli) flew into the cave, where they turned to stone. This is where the name “Zinzulusa” comes from.
The fairy punished the Baron by throwing him into the sea, creating an infernal lake called Cocytus. The girl, meanwhile, married a kind prince and lived happily ever after.
In reality, the cave features unusual limestone formations hanging from its highest sections, which popular tradition identifies as the girl’s petrified rags. In the lake below, Cocytus, there live specimens of pigmentless, blind shrimp.
The name of the cave is therefore traditionally attributed to the events described in the legend. According to other interpretations, however, it derives from the Greek and Arabic name of a tree that was once widespread in the area: the jujube tree, known as zinzinusa.
The cave was discovered by the Bishop of Castro in 1793 and was subsequently studied throughout the twentieth century. Numerous Neolithic and Paleolithic artefacts were found there, along with Roman-period objects and fossils of various animals, including hippopotamuses, bears, deer, felines and birds.
After decades of exploration and research, the cave was finally opened to the public in 1957.
This 300-metre-long karst cave can be accessed from land only with a tour guide, who accompanies visitors as they discover its stories and legends.
The Caves of Santa Maria di Leuca
The area around Santa Maria di Leuca is exceptionally rich in caves, all of them fascinating and different from one another, although some are particularly noteworthy.
Near the Ciolo Bridge are the Cipolliane Caves, accessible via the Sentiero delle Cipolliane, an ancient path that connects Mediterranean vegetation with the deep blue of the sea.
Other caves worth exploring in the area include:
– Grotta del Diavolo, or Devil’s Cave, is said to have acquired its name from the sounds and echoes that popular imagination attributed to devils. It is located in Santa Maria di Leuca, on Punta Ristola, and can be reached both by sea and by land.
– Grotta del Soffio is a “mysterious” cave, almost impossible to identify if you do not know it exists. Its name comes from the strange phenomenon that occurs inside: sprays and gusts of air become trapped within the cavity by the waves and cannot escape regularly, creating the impression that the cave is “breathing”.
What makes this small cavity even more fascinating is the so-called “Fata Morgana Effect”: the meeting of seawater with fresh water emerging from springs inside the cave creates an optical illusion that distorts images because of the different refraction of light.
To visit Grotta del Soffio, one option is to reach the entrance of the cavity and wait for the backwash created by the waves to retreat, leaving the entrance open. That is the right moment for a short swim into the submerged heart of the cave, revealing its most precious and hidden side.
– Grotta delle Tre Porte is certainly the most famous and most photographed of the caves of Leuca. It consists of three large openings that reveal an immense cavity.
On the northern wall of the cave’s inner chamber there is a passage that ends, after approximately 30 metres, in a large chamber containing stalactites and stalagmites.
Inside what is known as Grotta del Bambino, a left upper molar belonging to a child of approximately 10 years of age, dating back to the Neanderthal period, was discovered. In the passage, remains of a rhinoceros, an ancient elephant and a deer were also found.
The Caves of Porto Selvaggio
Among the caves along the Ionian coast of Salento, those of Porto Selvaggio stand out. These include Grotta del Cavallo, near Santa Caterina, an important testimony to Neolithic social life.
Other significant caves are Grotta di Uluzzo and Grotta Capelvenere, famous for the ferns that adorn its entrance.
Grotta Sfondata di Otranto
Located near Baia del Mulino d’Acqua, named in memory of a watermill that once stood near the bay, Grotta Sfondata di Otranto is a true natural paradise.
It takes its name from its characteristic rocky “opening”, created by the partial collapse of the roof, which forms an opening toward the sky.
Swimming inside Grotta Sfondata allows visitors to enjoy both sunlit areas, created by the opening in the rock, and shaded areas.
The sheer cliff prevents access from land, which is why the site can only be visited from the sea.
To visit it, simply park near Baia del Mulino d’Acqua and then make your way to the charming beach of Santo Stefano. From there, Grotta Sfondata can be reached by swimming or by boat.
Grotta Verde
Located near Marina di Andrano, in the area known as “La Botte”, where the coastline is particularly low, Grotta Verde can be reached by descending the cliff and swimming for a few metres.
Inside, light enters through the cracks in the rock, creating incredible emerald-green reflections.
The caves of Salento are an authentic natural treasure, a journey through history, legend and landscapes of unparalleled beauty.
Each cavity, with its crystal-clear waters and rock formations sculpted by time and the sea, tells a story that fascinates and enchants those fortunate enough to explore them.
Whether you love adventure or are passionate about nature, a visit to these caves will give you an unforgettable experience.
All that remains is to set off in search of these hidden gems, immersing yourself in a world of beauty and mystery, where nature reigns supreme.
