Grotta Sfondata
In Mulino d’Acqua bay there is a cave with a collapsed roof: from the water you see the hole to the sky and the light pouring in from above.

We pass it together with Mulino d’Acqua and Grotta delle Conchiglie, along the same cliff face.
Not a swim stop on its own — it’s the photo before heading back to swim at the Mulino.

A few stops on the NORTH tour — swipe for more or open the full list.
NORTHNORTH EXTENDEDGrotta Monaca
A narrow inlet between limestone cliffs north of Otranto, in the San Pietro channel: this is where Grotta Monaca opens, nearly 85 metres deep. Legend has it the name comes from the Mediterranean monk seal, once found in these waters.
NORTHNORTH EXTENDEDMulino d'Acqua bay
A bay set between cliffs north of Otranto, named after an old water mill that once stood here and is long gone — only the name remains. The beach has largely disappeared, and the bay is best seen from the sea.
NORTHNORTH EXTENDEDGrotta delle Conchiglie
Next to Grotta Sfondata, still in Mulino d’Acqua: a wide entrance and an inner tunnel you can swim through, with just enough headroom to breathe.
