Taking a look at the boat tour from Sperlonga to Gaeta offers a chance to explore some of Lazio’s most beautiful coastal sights from the water. While I haven’t personally taken this exact trip, the detailed reviews and itinerary paint a picture of a relaxing, visually impressive experience that balances sightseeing, swimming, and good company. What’s especially appealing is the chance to see iconic sites like the Montagna Spaccata and the Grotta del Turco, all while enjoying a casual cruise with snacks, drinks, and plenty of opportunity for a swim.
Two things I particularly like are the knowledgeable guides, like the friendly captain who told stories and pointed out key landmarks, and the variety of stops that give you genuine chances to swim in crystal-clear waters. The inclusion of a pizza and drinks package also adds a fun, informal touch that makes the cruise feel like a mini vacation rather than just another sightseeing tour.
One potential drawback to consider is that the sea can be choppier in the afternoon due to mistral winds, which might result in canceled trips if the weather turns bad. If you’re a confident swimmer or love spending time on the water, though, you’ll find the scheduled swim stops quite rewarding. The tour’s length of 4.5 hours strikes a good balance—long enough to see a lot without feeling rushed or overly tiring.
