Naples offers some of Italy’s most accessible and beautiful waters for snorkeling. Its stunning coastline, historic sites, and clear waters make it an ideal destination for underwater adventures. We particularly like the Argo Nautical Excursions tour for its well-rounded experience, combining stunning scenery, historical insights, and comfortable amenities on a 3-hour boat trip. This tour not only offers a chance to explore the waters around Castel dell’Ovo and Posillipo but also includes snorkeling in spots that hide caves and coves, making it perfect for those who want both relaxation and adventure.
If you’re looking for a longer day trip that combines snorkeling with island exploration, the Capri snorkeling tour is hard to beat. It takes you to one of Italy’s most famous islands, with the chance to swim in crystal-clear waters and see legendary sea stacks and caves. While the Capri tour is more about sightseeing and enjoying a full day on the water, the Gulf of Naples trip offers a more intimate, relaxing experience focused on snorkeling and local scenery. Below, we highlight the two best options to help you decide which suits your travel style.
1. Argo Nautical Excursions – Tour of the Gulf of Naples with Snorkeling

This guided 3-hour boat tour combines sightseeing with the chance to snorkel in the waters of Naples’ bay. The company offers comforts like a shower, inflatables, music, shaded area, fridge, pillows, and complete snorkeling equipment, including wetsuits during colder months. What stands out is the balance of relaxation and exploration—visiting iconic locations such as Castel dell’Ovo, Posillipo hill, and the Villas along the coast, all while having time for swimming and snorkeling.
The itinerary includes a 45-minute stop at Posillipo to snorkel in waters rich with caves and small beaches. The tour’s guides provide engaging historical commentary, making it an educational experience as well as an aquatic one. The reviews consistently praise the friendly staff, with many mentioning how Nico and Valeria make the trip fun with jokes and local tips. One guest noted, “Swim into hidden caves and collect sea glass—perfect for families and first-time snorkelers alike.”
This tour is great for those wanting a short yet fulfilling experience, ideal for cruise visitors or anyone short on time. It’s especially good if you appreciate comfort aboard a well-equipped boat and enjoy a mix of sightseeing, swimming, and snorkeling in a beautiful setting.
Bottom Line: A friendly, well-reviewed choice for a quick, scenic snorkel trip with historical insights and plenty of comfort.
2. Naples: Discover the island of Capri with snorkeling and drinks included
This full-day tour offers a chance to see the world-famous island of Capri, with a focus on snorkeling in its famously transparent waters. The trip includes visits to renowned caves, sea stacks, and hidden coves around Capri, making it perfect for those wanting to combine underwater exploration with sightseeing. You’ll spend about 8 hours on this adventure, with snorkeling in several spots along the coast.
What makes this tour stand out is the combination of natural beauty and the chance to relax on Capri’s scenic beaches. The experienced staff are dedicated to ensuring you have the best experience, providing snorkeling gear and local insights throughout the day. Many reviews mention how unforgettable swimming in Capri’s waters is, with some even calling it a “magical experience.” It’s especially suited for travelers who want to spend a full day exploring the island’s famous sights, with some time allocated for leisure, swimming, and enjoying drinks onboard.
Since this is a longer, more leisurely trip, it’s best for those comfortable with a full day on the water and who enjoy a mix of sightseeing and underwater activities. The trip’s popularity means early booking is advised, especially in peak season.
Bottom Line: A wonderful choice if you want a full-day, scenic experience that combines the allure of Capri with excellent snorkeling opportunities.
How to Choose Between These Snorkeling Tours
When deciding between these options, consider your timing, budget, and what kind of experience you want. The Argo Nautical Excursions trip is perfect for a quick, relaxing escape from the city, offering comfort and a taste of Naples’ coastal charm. It’s ideal if you’re short on time but want to snorkel in beautiful waters with historical highlights. The Capri trip, on the other hand, is best suited for those who want an entire day of discovery, combining island scenery with snorkeling in legendary waters. It’s more expensive and longer but offers a full immersion into one of Italy’s most iconic destinations.
For those on a budget or with limited time, the Naples Gulf tour provides great value, especially with positive reviews emphasizing its fun guides and picturesque spots. If you’re a serious snorkeler or seeking a memorable day in a world-famous setting, the Capri tour promises unforgettable moments in crystalline waters with the charm of a famous island.
Booking early is recommended for both, especially during peak months, to secure the best times and avoid disappointment.
Final Thoughts
Naples offers a surprisingly versatile set of snorkeling experiences. Whether you prefer a short, comfortable boat ride around the gulf, with its caves and coves, or a full-day adventure exploring the legendary island of Capri, there’s something for every water lover. If quick, fun, and scenic suits your schedule, the Argo Nautical Excursions is an excellent choice. For those seeking a more extensive experience packed with iconic sights and crystal-clear waters, the Capri snorkeling tour will not disappoint.
No matter which you pick, remember to book early, bring your sense of adventure, and enjoy the underwater treasures of Naples and Capri. Both tours promise memorable moments, whether you’re splashing into caves or relaxing on deck with a drink in hand. Happy snorkeling!
