Spiaggia di Calamuri

Spiaggia di Calamuri

“Calamuri” is a real place-name south of Otranto, also confirmed by the Speleological Register through Vora Calamuri. No institutional boundary for a standalone beach was found, so the pin is an area reference rather than a certified sea access.

Spiaggia di Punta San Nicola

Spiaggia di Punta San Nicola

The historic guide also used the local name “Filu de Mienzu”. The maritime ordinance officially identifies “Spiaggia San Nicola” on the cliff southeast of the harbour and defines a restricted sea area because of landslide risk.

Canale del Càfaro Cove

Canale del Càfaro Cove

A small rocky inlet on Otranto’s northern coast, between Staffa and the coves towards Grotta Monaca: clear water, paths and steps for access, an interesting seabed for snorkelling and virtually no facilities in the cove itself.

Spiaggia della Cattapìgnula

Spiaggia della Cattapìgnula

Cattapìgnula means “bat” in local dialect; local sources describe a cave used by bats and a sea-accessed cavity. The pin is approximate for the coastal sector.

A small rocky cove north of Otranto on the Hermit Trail, among caves and low limestone cliffs.

Cala di Grotta Monaca

Cala di Grotta Monaca

Grotta dell’Eremita

A large sea cave north of Otranto in the Mulino d’Acqua cave system, close to several neighbouring caves.

Scoglio di Sapunerò

Scoglio di Sapunerò

Sapunerò is a rocky landmark on Otranto’s northern coast, along the route between Grotta Monaca and Mulino d’Acqua; the pin is approximate because no standalone institutional coordinate was found.

Mulino d’Acqua Bay

Mulino d’Acqua Bay

A spectacular bay of cliffs, small inlets and sea caves. Today, however, the most important thing to know before you go is that sea access, bathing and remaining below the cliff are affected by safety restrictions.

Torre del Serpe

Lungomare di Otranto

This guide mainly covers Lungomare degli Eroi, the public promenade beside the historic centre; it should not be confused with Lungomare Terra d’Otranto or Lungomare Kennedy.
