The Best Places for Snorkeling in Sardinia (And How to Get There by Boat)

The Best Places for Snorkeling in Sardinia?

Sardinia is world‑renowned for its breathtaking coastline, crystal‑clear waters, and dramatic Mediterranean landscapes. But for many travelers, the true magic lies beneath the surface. From vibrant marine life to underwater rock formations and hidden sea caves, the east coast of Sardinia — particularly the Ogliastra region — offers some of Europe’s best snorkeling spots. What makes this area even more special is how many of these sites are accessible only by boat, allowing you to explore pristine underwater worlds far from crowds.

We invite you to discover the wonders of Sardinia’s east coast with thrilling boat trips into the heart of Ogliastra. Depart independently from the ports of Arbatax or Santa Maria Navarrese, or rely on the professionalism of our Nautilux Travel crew for guided tours that combine sea, sun, and freedom.

Why Snorkeling in Sardinia Is Special

Sardinia’s water is some of the clearest in the Mediterranean, thanks to its minimal pollution and protected natural areas. In Ogliastra, the seabed features incredible diversity: sandy flats, rocky walls, natural arches, and underwater grottos. These habitats attract colorful fish, octopus, sea urchins, and even small groupers — making every snorkel session exciting and memorable.

Many of the island’s most spectacular snorkeling spots lie along stretches of rugged coastline invisible from the road. Reaching them by boat is often the only option — and one of the most rewarding ways to discover Sardinia’s wild beauty.

1. Cala Goloritzé: UNESCO‑Listed Underwater Wonderland

Located within the Gulf of Orosei, Cala Goloritzé is one of Sardinia’s most iconic beaches — and its underwater world is equally impressive. The nearby seafloor changes dramatically from shallow sandy patches to deeper ledges, providing an ideal habitat for a wide range of marine species.

Why Snorkel Here:

• Clear water with superb visibility
• Rocky formations just below the surface
• Small fish and Mediterranean invertebrates

How to Get There:

You can reach Cala Goloritzé aboard a private boat tour or small group excursion departing from Arbatax or Santa Maria Navarrese. The bay’s remote location means access by sea is not only the most scenic but often the only convenient route.

2. Cala Mariolu: Turquoise Waters and Dynamic Marine Life

Next to Goloritzé lies Cala Mariolu, known for its pale pebble shore and vibrant, turquoise color. The underwater scenery is equally stunning, with rocky structures and numerous hiding spots for marine animals.

Why Snorkel Here:

• Excellent water clarity
• A varied seafloor with rocks, pebbles, and sandy areas
• Schools of small fish, sea bream, and occasional octopus sightings

How to Get There:

Cala Mariolu is reachable only by boat or by foot via a long hiking trail — making it a perfect destination for boat tours Sardinia. Nautilux Travel offers full‑day tours that include a stop here, giving you time both to swim and snorkel.

3. Piscine di Venere: Emerald Pools Beneath the Surface

The Piscine di Venere (Venus Pools) are shallow, emerald‑colored waters encircled by smooth rock formations. Apart from being a stunning swim stop, this area is ideal for beginners and families who want to see marine life in calm, shallow environments.

Why Snorkel Here:

• Shallow waters make for easy and comfortable snorkeling
• Ideal for kids and less experienced swimmers
• Colorful algae and small fish inhabit the rocky edges

How to Get There:

These natural pools are only accessible by boat, with many Nautilux tours including guided stops for swimming and snorkeling. Starting from Santa Maria Navarrese or Arbatax, the boat ride is part of the experience, passing hidden coves and scenic cliffs.

4. Cala Biriala: Hidden Cove with Dramatic Underwater Rocks

Cala Biriala is one of Ogliastra’s secret snorkeling gems. Framed by steep limestone cliffs and rarely reached by land, this cove is best explored from the sea.

Why Snorkel Here:

• Dramatic underwater rock formations
• Richer biodiversity near rocky ledges
• Peaceful waters away from the crowds

How to Get There:

Cala Biriala is almost exclusively accessible by boat. Many tours from Nautilux include a stop here, giving you time to snorkel and enjoy this sheltered cove’s peaceful atmosphere.

5. Grotta del Fico (Sea Grotto): Snorkeling with Light and Shadows

Sea grottoes create some of the most captivating snorkeling environments — and Grotta del Fico is one of the best examples on Sardinia’s east coast. While entering the grotto itself requires careful swimming, the waters just outside are rich in marine activity.

Why Snorkel Here:

• Dramatic cave walls and calm alcoves
• Light filtering through rock formations creates beautiful underwater visibility
• Unique habitat for small Mediterranean fish

How to Get There:

Access to this sea cave and the surrounding snorkeling spots is best achieved by joining a guided boat tour. Nautilux’s experienced captains know the safest approach points and can help you explore with confidence.

6. Cala Luna: Long Beach, Clear Waters, and Marine Variety

Cala Luna might be more famous as a beach destination, but its surrounding waters are also excellent for snorkeling. The bay’s curved shape shelters calm seas, making it a pleasant place for underwater exploration.

Why Snorkel Here:

• A mix of sandy and rocky seabeds
• Gentle waves and safe swimming conditions
• Possibility of spotting sea life close to shore

How to Get There:

Whether you choose a private charter or a small group tour with Nautilux, a boat trip to Cala Luna combines scenic coastal cruising with quality snorkeling stops. This area is better explored by sea — especially in summer when beach access by land can be crowded or difficult.
