Where to go snorkeling in Tuscany?

Let’s take a look at some of the most scenic destinations for snorkeling in Tuscany.
Snorkeling in Argentario
Argentario is a true gem for snorkeling enthusiasts. Its rugged coastline, with rocky coves and deep waters just steps from shore, is home to vibrant, life-filled sea beds.
Grotta Azzurra, Cala dei Santi and Punta Ciana are just a few of the spectacular spots for snorkeling. Here, you can explore rock walls covered in algae, gorgonians and sponges, with a chance to spot moray eels, nudibranchs and schools of Mediterranean fish.
For maximum safety and fun, we recommend joining one of the snorkeling excursions offered by Argentario Divers, ideal for both adults and children. Our experienced guides will take you to the most beautiful and less crowded sites.

Snorkeling in Porto Santo Stefano
Porto Santo Stefano, one of Argentario’s two main towns, is a great base for snorkeling excursions. Boats regularly depart from here to reach secluded coves accessible only by sea, or you can start from the shore and snorkel areas like Cala Moresca and Punta Nera.
The waters here are deep and clear—perfect for those with some experience or for guided snorkeling trips.
Snorkeling on Giglio Island
Giglio Island, just a short boat ride from Argentario, is a haven of unspoiled nature. Its famously clear waters and diverse seabeds—sand, rocks and seagrass—make it ideal for snorkeling.
Top spots include Cala dell’Arenella, Cala delle Caldane and Punta del Fenaio. Water visibility remains excellent even in high summer, and the shallow sea beds are home to mullet, red mullet, sea urchins and starfish—perfect for beginners too.
Snorkeling on Elba Island
Elba Island is one of the most popular seaside destinations in Tuscany—and for good reason. Snorkeling here reveals breathtaking scenery.
Don’t miss Capo Sant’Andrea, Pomonte (where the Elviscot shipwreck lies just offshore), and Spiaggia di Sansone, famous for its turquoise waters and rocky sea bed.
Elba offers great variety: from easy-access sandy beaches to wilder rocky areas perfect for observing marine life in its natural habitat.
Snorkeling in Maremma
Maremma, the stretch of coastline between Grosseto and Argentario, offers stunning natural landscapes and quieter spots. Snorkeling here is often underrated—but full of surprises.
The Uccellina Park area, near Talamone, is ideal for peaceful underwater exploration. The rocky sea beds are rich in fish and invertebrates, and the low tourist impact helps preserve a pristine marine environment.
Where to snorkel with kids in Tuscany
Snorkeling is a perfect activity for the whole family—even with children. The key is choosing spots with calm, shallow waters and easy beach access.
Some of the best family-friendly locations include Cala dei Santi (Argentario), Cala Maestra (Giannutri Island) and Cala dell’Arenella (Giglio Island). These are great places for kids to spot their first colorful fish safely, ideally accompanied by an adult or guide.
Argentario Divers also offers family-friendly snorkeling tours, complete with suitable gear and an initial safety briefing for children.

When is the best time for snorkeling in Tuscany?
The ideal season for snorkeling in Tuscany runs from May to October, when the sea is warmer and clearer. The top months for visibility and water temperature are June, July, August, September and early October.
In summer, Tuscan waters reach 25–27°C, perfect for long snorkel sessions without a wetsuit. During peak season (July and August), it’s best to snorkel early in the morning or late afternoon for optimal calm and clarity.
In spring and autumn, the water is cooler but often clearer. A light wetsuit will let you enjoy an equally beautiful and quieter experience.
What equipment do you need for snorkeling in Tuscany?
You don’t need technical skills or big investments to snorkel in Tuscany. Just a few essentials will ensure comfort and safety:
- Mask – should fit snugly to prevent leaks and provide clear underwater vision.
- Snorkel – choose one with a purge valve and splash guard to breathe easily.
- Fins – help you move effortlessly and stay stable, especially in light current.
For non-swimmers or anyone feeling unsure in the water, wearing a wetsuit or life vest is crucial. They add buoyancy, comfort and confidence.
To fully enjoy your experience, we recommend high-quality snorkeling masks with wide panoramic lenses and soft silicone for maximum comfort and visibility.
A neoprene wetsuit also helps with buoyancy, keeps you warm, protects from sun and irritation—great for sensitive skin.
If you join a snorkeling tour with Argentario Divers, we provide all necessary equipment, cleaned and ready to use: masks, fins, snorkels and short wetsuits in all sizes—including for kids.
The right gear makes your experience safer and more enjoyable, so you can focus on what really matters: the beauty of the sea.
