What’s scuba diving like in Sardinia?
During the right season, Sardinia is a scuba diver’s dream with pristine waters and fascinating dive sites. From maze-like caves to historical wrecks, curious crustaceans, and intriguing corals.
There is a wide array of unique diving all around the island to suit every divers taste.
Sardinia is particularly famous for its shipwrecks. Because of its position in the middle of the Mediterranean sea, Sardina has been on Europe’s most traveled sea route throughout history. You can find every kind of wreck here, from ancient roman boats to World War 2 battleships, airplanes, submarines, and cargo ships.
The abundance of enchanting caves and caverns dotted along the island’s limestone coastline is also another reason why Sardinia is considered one of the best scuba diving destinations in the Mediterranean.
You’ll find plenty of options for both boat and shore diving all around the island. As well as dedicated tech diving sites.
What can you see scuba diving in Sardinia?
Throughout the summer, Sardinia welcomes a surprisingly wide variety of Mediterranean marine life. You have the opportunity to find tuna, barracudas, huge groupers, bamboo sharks, turtles and several types of rays. As well as moray eels, octopus, squid, lobsters, scorpionfish, pipefish, seahorses and many nudibranchs.
Dolphins will frequently accompany dive boats. And if you’re really lucky, you can even spot the elusive sunfish. Your best chance is between March and June when the waters are still a little colder.
Most marine life heads to warmer waters in the winter but you’ll still find an impressive amount of macro life during these months. And stunning sea fans, sponges and red corals can be seen year-round at the majority of the dive sites.

The Best Dive Sites in Sardinia
3 Fratelli (3 Brothers) Wreck
Resting in fantastically clear water, this well preserved World War 2 cargo ship is a dive site for wreck lovers. This dive site is also rich in schooling fish and home to many stingrays, giant groupers and scorpionfish. Lying at around 30m this dive site is only accessible to advanced divers and enriched air nitrox is recommended.
Likely one of the most famous caverns to dive in the world, Ghost cave is truly breathtaking. Just 5 meters deep, divers enter into a small tunnel that opens up into this mesmerising cave. While this site doesn’t have crazy amounts of wildlife, the structure of these caverns is 100% worth seeing.
It’s important to have good buoyancy and controlled kicks as it’s easy to kick up the silt settled on the bottom and lower the visibility.
Grotta di Nereo (Nereo Cave)
As one of the largest underwater cave systems in Europe, Grotta di Nereo is not to be missed when scuba diving in Sardinia. This stunning series of caves, arches and tunnels reach over 350m (1150 ft) deep into the mountainside.
Octopus, red and yellow corals, lobsters, shrimp, nudibranchs and Pinna Nobilis, the world’s largest mussel, are all found here as sea currents bring vital nutrients into the cave system.
Papa 1 & 2 Banks
These sandbanks, located on the east side of Tavolara island, are famous for their variety of vibrant gorgonians, including the rare yellow and red varieties. Encounter snappers, jacks and big groupers weaving between these giant sea fans and across the anemone covered walls of Tavolara It’s also possible to spot mobula rays, yellowtail tuna and moray eels here.
Grouper City or Reef
Home to a friendly colony of over 50 groupers, each weighing 30-40kg (66-88lbs), this dive site is one of the most popular dive sites in Sardinia. Get up close and personal with these grumpy looking giants as well as big snappers, barracuda, sea bass and jacks schooling above the rocky bottom.
This massive 230ft wreck, sunk by submarines in WW2, looms out of the blue as you start your descent. A seriously impressive view. Inside you’ll easily find grouper, conger eels and a variety of crustaceans. And there’s always huge schools of snapper, mullet and sea bream swirling around the outside of the ship.
When to go scuba diving in Sardinia
With hot, dry summers and cooler yet humid winters, Sardinia experiences a typical Mediterranean climate. You can dive all year round in Sardinia but conditions are best during the summer months.
Although the water can still be a little cool, May is arguably the absolute best time to go scuba diving in Sardinia. The prices are reasonable, the dive sites are relatively quiet and the visibility is excellent, up to 40m most days.
Summer (April – September)
During the summer season, water temperatures can reach 26°C (82°F) but there is normally a thermocline at around 12m (40 ft) where the temperature will drop down to 15°C (59°F).
July and August are considered the peak season in Sardinia when accommodation prices often double and dive sites can be very busy. So it’s better to avoid these months if possible.
Visibility is best at the beginning of the summer, in May and June, but the water can still be quite cold. The sea is warmest towards the end of the season in September and October, but thunderstorms are more likely.
Winter (October – March)
In the winter, water temperatures remain around 12°C (54°F), visibility is reduced and a lot of the marine life disappears. So it’s best to avoid this time of year.
But if you’re looking for a cheap deal on diving and accommodation, consider visiting at the start or end of this season when conditions are still good and prices are low.

Where to stay when scuba diving in Sardinia
Although Sardinia is relatively easy to travel around it’s still one of the largest islands in the Mediterranean so it makes sense to stay in or near the areas you want to dive in. Sardinia offers a wide range of accommodation options to suit all budgets including hostels, hotels and full-service resorts.
If you only have 1 week, we recommend picking one area, for example, Costa Paradiso in the North, where you can enjoy both the Asinara and La Maddalena Marine parks.
But if you have more time, we recommend staying in a few different areas to really make the most of scuba diving in Sardinia. We recommend basing yourself in Orosei in the East and Cagliari the South if you want to be able to access the widest variety of dive sites.
Or if you’re looking for a more relaxed setting and untouched dive sites, consider a stay on the relatively undeveloped and beautiful island of Sant’antioco.
