In short. The coast around Vieste, on the Gargano, is drilled through with sea caves — emerald to deep turquoise, reachable only from the water. You can join an organised boat trip, hire a small motorboat, or for a few of them simply paddle. The best-known ones have names, and the names explain them.
Seeing this coast from the sea is a different experience from seeing it from the road above. The cliffs are higher than they look, and the caves are the reason people come back.
🚤 How to see them
- Organised excursion — the simplest, and the guides know which caves take the light at which hour
- Hired motorboat — more freedom, and necessary for the caves further out
- Pedalo or kayak — enough for a few of the closer ones only
The setting is white limestone cliffs falling straight into the water, broken here and there by inlets, caves and tiny beaches that can only be reached by sea, with broom and orange blossom on the rock above. Kestrels and gulls overhead; below, shoals of fish and, with luck, a turtle.
🕳️ The ones worth asking for
- Grotta dei Contrabbandieri — the smugglers’ cave, with an entrance to the north and another to the south, which is exactly why they used it. A trabucco sits on top of it.
- Grotta Calda, also called Viola — there is a warm spring inside, so both air and water are warm; the violet comes from the light.
- Grotta dei Due Occhi — two clefts in the rock let the light in like a pair of eyes.
- Grotta Sfondata — the roof has collapsed over time, and Aleppo pines now lean in over the opening, throwing green reflections on the water.
- Grotta dei Pomodori — the walls look studded with cherry tomatoes. They are red marine invertebrates, and they sting: do not touch.
- Grotta Campana Grande — about 50 metres high, lined with green moss, with a pebble beach inside and room to linger.
- Grotta della Tavolozza, or delle Rondini — ten metres long, coloured like a painter’s palette, and full of swallow and bat nests.
The colours change through the day. The light entering a sea cave from below is what produces the emerald and the deep blue — so the same cave looks different at ten in the morning and at five in the afternoon. Ask when you book.
The sirens. Local legend gives the caves to the sirens, who are said to have used them to imprison the most beautiful girls of the coast out of jealousy. One of the caves is called Grotta delle Sirene for exactly that reason.
🧭 Where you are
Vieste sits on the eastern tip of the Gargano, the spur of the Italian boot — limestone, forest and sea, and the most dramatic coastline in Puglia. The caves are spread between the headland itself and the bays of Campi, Portogreco, Pugnochiuso, the Gabbiani and the Zagare, so any trip from Vieste, Peschici or Mattinata reaches some of them. Offshore lie the Tremiti islands.
