Sailing the Adriatic: Hidden Croatian Islands You’ve Never Heard Of

When people think of Croatia, their minds often drift to Dubrovnik’s medieval walls or the bustling nightlife of Hvar. But the true magic of Croatia lies not only in its well-known tourist hubs, but also in the quiet, undiscovered islands scattered like pearls across the Adriatic. These hidden treasures remain largely untouched by mass tourism, offering travellers the perfect combination of natural beauty, local traditions, and authentic seafaring charm.

For the smart traveller, exploring Croatia by sailboat is more than just a holiday- it’s a journey into the soul of the Adriatic. From tranquil bays to historic fishing villages, this article will take you through the lesser-known islands you’ve probably never heard of, while also showing you how to stay connected and navigate your way seamlessly along the coast.

Why Sail the Lesser-Known Islands of Croatia?

The Croatian coastline stretches for over 1,700 kilometres, dotted with more than 1,200 islands, islets, and reefs. While only about 50 of them are inhabited, each has its own story to tell. Sailing offers unparalleled freedom: you’re not tied to crowded tourist ferries, you can drop anchor in secluded coves, and you’ll find yourself immersed in a more intimate side of Croatian culture.

Mass tourism has undoubtedly touched destinations like Hvar or Korčula, but venture off the beaten sailing routes, and you’ll encounter communities where fishermen still haul in their catch every morning, locals produce olive oil the same way they have for centuries, and the Adriatic’s turquoise waters feel like your own private paradise.

Vis: The Island of Timeless Isolation

Perhaps the most famous of the “hidden” islands, Vis has a unique charm born from its history. For much of the 20th century, Vis was a closed military base, off-limits to outsiders until the late 1980s. Because of this isolation, the island preserved its authenticity.

What to See and Do

• Stiniva Cove: Often listed among Europe’s most beautiful beaches, this narrow inlet is framed by towering cliffs and accessible only by boat or a steep hike.

• Blue Cave on Biševo: Just off the coast of Vis lies the Blue Cave, where sunlight creates an otherworldly blue glow in the waters. Best visited early in the morning, it’s a must for sailors.

• Wine and Seafood: Vis is renowned for its local wines, especially Vugava and Plavac Mali, and its fishing tradition means you’ll enjoy some of the freshest seafood in Croatia.

Why Sail Here?

Vis remains less crowded than other islands. The harbour towns of Vis and Komiža are perfect stopovers, and sailors often say that docking here feels like stepping back in time.

Lastovo: A Starry Sky Sanctuary

The island of Lastovo is one of the most remote inhabited islands in Croatia, part of the Lastovo Archipelago Nature Park. Its remoteness is exactly what makes it so special- it’s untouched, serene, and offers some of the clearest night skies in Europe.

What to See and Do

• Astronomy Haven: Because of the island’s minimal light pollution, Lastovo is designated a Dark Sky Park. Stargazing from the deck of your sailboat is a once-in-a-lifetime experience.

• Nature Park Trails: Hike through pine forests, olive groves, and vineyards that cover the island.

• Local Festivals: The island’s carnival traditions and summer festivals give a glimpse into its rich cultural heritage.

Why Sail Here?

Few ferries make the long trip, so arriving by sailboat gives you access to pristine bays, hidden anchorages, and some of the Adriatic’s most unspoiled waters.

Mljet: The Island of Myth and Nature

Legend has it that the nymph Calypso held Odysseus captive on Mljet for seven years. Today, it’s an island where myth blends with lush greenery and tranquil saltwater lakes.

What to See and Do

• Mljet National Park: Covering the island’s western third, it features two saltwater lakes, Veliko and Malo Jezero, perfect for kayaking and swimming.

• Monastery on St. Mary’s Islet: In the middle of Veliko Jezero, this Benedictine monastery is a peaceful place steeped in history.

• Cycling Routes: The park offers excellent bike paths, allowing you to explore at your own pace.

Why Sail Here?

Anchoring near Pomena or Polače provides direct access to the park, making Mljet a dream destination for eco-conscious sailors.

Šolta: Olive Groves and Fishermen’s Charm

Just a short sail from Split, Šolta remains surprisingly overlooked. While close to the mainland, it retains the feel of a secluded island, known for its olive oil, honey, and traditional fishing villages.

What to See and Do

• Maslinica: This harbour town is surrounded by seven small islands and is a favourite among sailors looking for tranquillity.

• Olive Oil Tastings: Šolta produces some of Croatia’s finest olive oil, often regarded as liquid gold.

• Kayaking and Diving: With crystal-clear waters, Šolta offers perfect conditions for sea kayaking and diving.

Why Sail Here?

For those who want to escape crowds without travelling too far, Šolta provides the best of both worlds: convenience and serenity.

Susak: The Island of Sand and Tradition

Unlike most rocky Adriatic islands, Susak is unique for being formed almost entirely of sand. Its distinctiveness doesn’t stop there- the island has its dialect, folk costumes, and traditions that differ from the rest of Croatia.

What to See and Do

• Sandy Beaches: Rare in Croatia, Susak offers wide sandy shores perfect for families.

• Local Culture: Women here traditionally wear short, brightly coloured skirts, unlike anywhere else in the country.

• Secluded Atmosphere: With no cars and few tourists, Susak feels like stepping into another world.

Why Sail Here?

Its isolation and lack of ferry connections make Susak a true sailor’s discovery. You’ll likely share the anchorage with only a handful of other boats.

Sailing Tips for Exploring Croatia’s Hidden Islands

When to Go

The best sailing season runs from May to October, with July and August being the busiest months. For quieter coves and lower prices, June and September are ideal.

Chartering a Boat

You can either rent a bareboat yacht if you have sailing experience or opt for a skippered yacht if you prefer to leave navigation to a professional.

Staying Connected at Sea

Even while sailing remote islands, staying connected is important for navigation, bookings, and sharing your adventures. That’s where the eSIM for Croatia by Voye Global comes in. Instead of dealing with physical SIM cards or high roaming charges, an eSIM provides instant activation and reliable data across the Adriatic. It ensures you can use navigation apps, find local restaurants, and upload your stunning sunset photos without interruption.

Why These Hidden Islands Matter

Travelling to lesser-known destinations isn’t just about avoiding crowds- it’s about supporting local communities, preserving cultural traditions, and discovering the raw beauty of nature. Croatia’s hidden islands remind us that the Adriatic isn’t just about luxury yachts or trendy beach clubs- it’s about simplicity, authenticity, and the rhythm of the sea.

Sailing these islands allows you to experience Croatia as it truly is: a country where history, nature, and culture meet in perfect harmony. Whether you’re sipping wine in a centuries-old vineyard on Vis, stargazing under Lastovo’s dark skies, or anchoring in a sandy bay on Susak, each moment becomes a memory worth cherishing.

Conclusion: Sailing Smarter, Travelling Better

Croatia’s Adriatic islands are a sailor’s dream, but the real treasures lie in the hidden ones- quiet, authentic, and breathtaking. Exploring them offers a rare opportunity to step away from the well-trodden path and embrace travel at its purest form.

To make your journey smoother, smarter, and more connected, consider equipping yourself with tools like Voye Global’s eSIM for Croatia, ensuring you’re never out of reach while still immersed in the island’s raw beauty.

Sail the Adriatic not just to see Croatia, but to truly experience it. Because sometimes, the best destinations are the ones you’ve never heard of.
