Adriatic Coast, Italy
Bari, Polignano a Mare, and Monopoli sit within 30 km of each other on a stretch of limestone coastline with sea caves, clear water, and no road access to most of the best swimming spots.
Bari, Polignano a Mare, and Monopoli are all within 30 km of each other. The coast between them is made of limestone — which means sea caves, vertical cliff faces, and water clarity that's noticeably better than the Tyrrhenian side of Italy.
Bari has a large old town and the Basilica di San Nicola — better for a city cruise. Polignano sits on a cliff promontory with caves directly below the old town — better for cave tours. Monopoli has a quieter white harbor with fewer tourists.
The northern Adriatic is calmer and murkier; the central Adriatic near Puglia has better clarity — typically 8–15 m visibility in summer. The limestone seabed creates defined underwater features that make snorkeling more rewarding than sandy-bottom coastlines.
Puglia sees far fewer international visitors than Amalfi or Capri. In May, June, and September you can reach sea caves and coves on a shared tour with 8–12 people rather than queuing with 50. July and August are busier but still less crowded than the Tyrrhenian.
