The rectangular tunnel carved into the rock is 20 m long. If you are sure-footed, you can get across dry straight from the beach. A magnificent view of the harbor bay and the grottos opposite awaits you.

The region offers two main types of caves: dramatic sea caves along the coast, particularly around Polignano a Mare, and extensive inland karst cave systems like the Castellana Caves. Sea caves are carved by the ocean, while karst caves feature intricate underground formations of stalactites and stalagmites.
The most recommended way to experience the sea caves around Polignano a Mare is by boat tour. This allows you to admire their unique colors, light reflections, and access caves like Grotta delle Rondinelle and Grotta Azzurra, which are best viewed from the water. Some caves, like Tunnel to Grotta Piana and Grotta del Bassi, Porto, can be accessed by foot if you are sure-footed.
Yes, the Castellana Caves (Grotte di Castellana) are a major regional attraction. Located inland, they are one of the largest karst cave systems globally, stretching over three kilometers and reaching depths of 70 to 120 meters. They feature stunning stalactites, stalagmites, underground lakes, and the famous Grotta Bianca.
Some coastal grottos are accessible by foot, especially around Polignano a Mare. For example, Ardito Cave is situated along a rocky coast with numerous grottos offering views of the historic city center. For more adventurous explorers, St. Anthony of Monacoli Cave is a less touristic option, requiring appropriate footwear and suited for enthusiasts.
One unique experience is dining inside Grotta Palazzese in Polignano a Mare, a high-end restaurant set within a natural sea cave. The Castellana Caves also offer a unique experience with their extensive underground tours, including the breathtaking Grotta Bianca known for its rich alabaster formations.
Yes, the Castellana Caves offer guided tours suitable for families, with options for a shorter 1 km route. The Lama Monachile and Chiangella Cave area in Polignano a Mare is also considered family-friendly, offering a beautiful urban beach with clear water and the magical Grotta della Chiangella.
For inland karst caves like Castellana, the internal temperature is a constant 16.5°C, so a light jacket is advisable. For sea caves or those requiring walking, wear comfortable, sturdy shoes. If exploring less touristic spots like St. Anthony of Monacoli Cave, appropriate footwear for uneven terrain is essential.

Yes, for those seeking a more challenging experience, the Smugglers' Caves at Lama San Giorgio offer a demanding technical route. Similarly, St. Anthony of Monacoli Cave is described as suitable for enthusiasts and young explorers due to its non-touristic route and access difficulty.
The region is rich in karst phenomena. The sea caves are characterized by erosion from water and wind, creating unique formations and dramatic cliffs. The inland Castellana Caves showcase classic karst features like stalactites, stalagmites, columns, and underground lakes, formed by the dissolution of soluble bedrock such as limestone.
The sea caves are best visited during warmer months (spring to early autumn) when boat tours are more frequent and sea conditions are calmer. The Castellana Caves, with their constant internal temperature, can be visited year-round, though booking in advance is recommended during peak tourist seasons.
