Gaeta offers some of the most captivating waters in Italy, with clear, inviting seas that make for excellent snorkeling. Unlike just lounging on the beach, these boat excursions and sea adventures let you see hidden spots and spectacular underwater landscapes that are unreachable from land. Personally, I find that the boat trip to Gaeta with snorkeling provides a perfect blend of scenic beauty, history, and fun in the water, especially with stops that showcase Gaeta’s ancient fortifications and natural pools. For a longer, more immersive experience, the Gaeta – Sperlonga boat tour takes you along the entire coast, offering multiple swimming and snorkeling spots. If you prefer exploring sea caves and discovering marine life at your own pace, then the snorkeling in Riviera di Ulisse is an excellent option with small group intimacy and flexible scheduling.
Below, I’ve compiled the three best snorkeling experiences in Gaeta, each with its own appeal — from quick, scenic boat trips to full-day coastal explorations and cave adventures. Whether you’re short on time or seeking a detailed underwater discovery, there’s a tour that fits your style.
