When people think about responsible boating, they often picture simple habits: taking your waste with you, respecting anchoring restrictions, or keeping an eye on fuel consumption.
But your choice of destination matters too. Across the Mediterranean, some regions have introduced practical measures to protect their marine environments while continuing to welcome sailors and visitors on the water. The best part? Many of these places also happen to be among the Mediterranean’s most beautiful destinations.
From Croatia’s wild islands and Greece’s protected marine parks to some of France and Italy’s best-kept coastal treasures, here are 7 of our favorite eco-friendly destinations for exploring unspoilt waters and finding inspiration for your next boat rental in the Mediterranean.
1. Port-Cros, France’s pioneering marine sanctuary
Just a few minutes from the Var coastline, it feels as though you’ve travelled much further than the distance suggests.
On Port-Cros, there are no cars, the coves remain wonderfully untouched, and the water is often so clear that you can see the seabed straight from the deck. Established in 1963, Port-Cros National Park was Europe’s first marine national park and remains one of Europe’s leading examples of coastal conservation.
Beneath the surface, marine life is everywhere. Curious groupers, shoals of barracuda, starfish and vast seagrass meadows create an extraordinary underwater landscape. To help protect it, some activities are regulated, anchoring is carefully managed and, in some areas, visiting boats use eco-moorings designed to avoid any contact with the Posidonia seagrass meadows.
All it takes is a quick look below the surface to understand why these measures matter. It’s also one of those rare destinations where the rules never feel restrictive. If anything, they enhance the experience.

- The turquoise waters of Port-Man Bay
- The park’s underwater nature trail
- The many secluded coves accessible only by boat
Best departure points
Hyères is the natural gateway to Port-Cros. You can also reach the national park from Giens or La Londe-les-Maures, both excellent starting points for exploring the Îles d’Or.
2. Cabrera, the Balearics’ best-kept secret
Less than an hour’s sail from Mallorca, the Cabrera archipelago feels worlds away from the island’s busy resort towns.
There are no beach clubs here, no rows of marinas stretching along the coastline. Instead, you’ll find a scattering of wild islets, dramatic limestone cliffs and remarkably clear water.
Protected for decades, Cabrera is one of Spain’s best-preserved natural areas. Moorings are limited, and visitors must reserve a spot in advance. During the height of summer, only a few dozen mooring buoys are available each night across the entire archipelago. What might sound restrictive at first quickly becomes part of the appeal once you experience the peace and quiet that defines the islands.
As evening falls, the last boats depart and the fading light settles across the cliffs. It’s easy to see why so many sailors consider Cabrera one of the most rewarding stops in the Balearics.
Don’t miss
- The famous Blue Cave
- Moorings within the national park
- The crystal-clear waters around the main island
Best departure points
Colònia de Sant Jordi is the closest departure point. Cala d’Or and Portocolom are also excellent bases for exploring Mallorca’s south-east coast before heading to Cabrera.
3. Mljet, Croatia at its wildest
When planning a sailing trip in Croatia, places like Dubrovnik, Hvar and Split tend to steal the spotlight. Mljet, meanwhile, remains relatively under the radar – and that’s exactly what makes it special.
Covered in forest, fringed with peaceful bays and largely protected as a national park, the island moves at a different pace from much of the Adriatic. This protected status has helped Mljet retain a far more natural character than many neighbouring Croatian islands, with very little large-scale tourism development along its shores.
Sailors are drawn here by the sense of calm. There’s no pressure to chase the next fashionable stop. Instead, you spend your days swimming in clear water, enjoying the silence and lingering at anchor as the sun slips behind the hills.
Don’t miss
- The saltwater lakes of Veliko and Malo Jezero
- The sheltered coves along the north coast
- The small fishing villages scattered around the island
Best departure points
Dubrovnik and Korčula both offer easy access to Mljet. Split is also an excellent starting point for a longer sailing itinerary through southern Croatia.
4. Zakynthos, where dramatic cliffs meet sea turtles
Some photos of Zakynthos look almost too beautiful to be real. Towering white cliffs plunge into electric-blue water, sea caves can only be reached by boat, and hidden beaches appear unexpectedly around the next headland.
But Zakynthos is more than just a picture-perfect island. It’s also home to one of the Mediterranean’s most important nesting grounds for loggerhead sea turtles (Caretta caretta). Each year, several of the island’s beaches become nesting sites for this iconic species. During nesting season, certain stretches of coastline are closed after sunset, allowing hatchlings to reach the sea without being disoriented by artificial light.
Over the years, a range of conservation measures has been introduced to protect these sensitive habitats. Boats can still access the area, but a handful of simple rules help minimise disturbance to local wildlife.
It’s a great example of how a place can protect what makes it special without preventing people from enjoying it from the water.
Don’t miss
- The Blue Caves
- The spectacular cliffs along the west coast
- The beaches within the National Marine Park
Best departure points
Lefkada and Preveza offer the widest choice of boats for exploring the Ionian Islands, including Zakynthos. If you’re planning a longer itinerary, Corfu is another excellent departure point.
5. Alonnisos, one of Greece’s last truly unspoilt islands
If you’re looking for the Greece of quiet coves, pine-covered shores and peaceful anchorages, Alonnisos is hard to match.
The island forms part of the Northern Sporades National Marine Park, one of the largest protected marine areas in Europe. It’s also one of the last refuges of the Mediterranean monk seal. Several sea caves used by the species for breeding are completely off limits, helping to preserve the tranquillity these animals depend on. The result is an archipelago that feels wonderfully untouched, benefiting both wildlife and those lucky enough to explore it by boat.
Far removed from the bustle of the Cyclades, Alonnisos offers a quieter, more authentic side of Greece. It’s the sort of place where you plan to stay for one night and somehow end up spending several days.
Don’t miss
- The secluded coves of the marine park
- Alonnisos’ charming old hilltop village
- The uninhabited islets scattered across the Sporades
Best departure points
Skiathos is the most convenient base for exploring the Sporades. You can also depart from Kolios on the island’s south coast or from Volos on the Greek mainland.
6. La Maddalena, Sardinia’s wild jewel
If there were one destination in the Mediterranean capable of rivalling the Caribbean, La Maddalena would be high on the list.
The archipelago is famous for its turquoise water, immaculate beaches and wind-sculpted granite formations. Yet behind these postcard-perfect landscapes lies a long-standing commitment to protecting the environment.
Since the national park was established, a number of regulations have helped protect the most sensitive marine habitats while still allowing visitors to enjoy the area to the fullest. Anchoring is carefully managed in certain zones to preserve Posidonia seagrass meadows, and some of the most fragile seabeds are subject to restrictions or anchoring bans.
Honestly, it’s difficult to imagine a better place to spend the day swimming, paddleboarding and enjoying lunch at anchor surrounded by some of the clearest water in the Mediterranean.
Don’t miss
- The islands of Spargi and Budelli
- The crystal-clear waters of Cala Corsara
- The many anchorages framed by pink granite rock formations
Best departure points
Palau is the main gateway to the archipelago. Alternatively, you can depart from Olbia and include La Maddalena as part of a longer sailing itinerary around Sardinia.
7. Tavolara, a paradise beneath the surface
Just a few nautical miles from Olbia, Tavolara rises dramatically from the sea. This towering limestone island, visible from miles away, marks the entrance to a protected marine area renowned for the richness of its underwater world.
And if the waters here remain so remarkably well preserved, that’s no coincidence. The marine reserve was created to protect particularly valuable habitats, with certain fishing activities restricted in the most sensitive areas. The result is a thriving marine ecosystem that continues to flourish today, making Tavolara a favorite among divers and snorkelers alike.
Less well known than nearby La Maddalena, Tavolara nevertheless offers some of Sardinia’s most beautiful anchorages. Even in the height of summer, the atmosphere tends to be calmer and more relaxed.
It’s a reminder that some of the Mediterranean’s most memorable discoveries are often found just beyond the places everyone already knows.
Don’t miss
- The crystal-clear waters of the marine reserve
- The coves surrounding the island
- Outstanding snorkelling spots teeming with marine life
Best departure points
Olbia is the ideal gateway to Tavolara. Porto San Paolo and San Teodoro also provide easy access to the protected marine area.
A different side of the Mediterranean
Choosing a destination that actively protects its natural environment doesn’t just influence the impact of your trip – it often changes the experience itself.
Quieter anchorages, thriving marine life, beautifully preserved landscapes and, sometimes, the feeling that you’ve stumbled across a corner of the Mediterranean that has escaped the pressures of mass tourism.
If these destinations remain so special today, it’s because they’ve found a balance between enjoying life on the water and protecting the marine environments that make them unique. And a few simple eco-friendly boating habits can help every boater play a part in preserving them for the future.
All that’s left to do is find the perfect boat on SamBoat and start planning your next Mediterranean adventure.
