On the dramatic coastline of Santa Cesarea Terme, in Puglia's Salento peninsula, the Piscina Sulfurea occupies a pool carved straight into the cliff, fed by water rising from a marine karst cave just below. The site is part of a group of four natural sea caves — Fetida, Sulfurea, Gattulla and Solfatara — whose waters, rich in sulfur and bromo-iodic salts, emerge directly from the limestone bedrock.

Rediscovered in the 19th century after centuries of neglect following the Ottoman conquest of Otranto in 1480, these springs led to the Gattulla thermal establishment, inaugurated in 1910. The Piscina Sulfurea today offers direct access to the Adriatic Sea and a cliffside solarium, set against the white limestone cliffs typical of the Salento coast.

Insider tip — Piscina Sulfurea near Tricase at the very tip of the Salento peninsula taps sulfurous thermal waters at 38°C emerging just metres from the Adriatic coast, creating a rare hot-spring-meets-sea experience. The surrounding Lecce limestone landscape of dry-stone walls, fig trees, and prickly pear gives the site a strongly local, unmanicured character. The aquamarine waters of the Adriatic can be seen from the pool edge. Visit in May or September when tourist numbers are low and the sea temperature remains pleasant for alternating hot spring and ocean dips.
