When you think of island getaways, you probably imagine popular spots like Hawaii, Bora Bora, or maybe even the Maldives. But what if I told you that some of the most incredible islands in the world remain under the radar? These hidden gems are home to awe-inspiring landscapes, vibrant cultures, and unforgettable experiences waiting to be discovered. Whether you're craving adventure, serenity, or something in between, these six lesser-known islands will spark your wanderlust and leave you dreaming of your next trip.

Pack your curiosity, and let's explore six incredible islands you’ve (probably) never heard of—but absolutely need to visit.

1. Lord Howe Island, Australia

Tucked away in the Tasman Sea, Lord Howe Island is like a postcard brought to life. This small, crescent-shaped island is known for its lush greenery, crystal-clear waters, and unique wildlife. It’s so pristine that only 400 visitors are allowed at a time to preserve its natural beauty.

Why It’s Special

Lord Howe Island is a paradise for outdoor enthusiasts. It’s home to Mount Gower, a challenging yet rewarding hike that offers panoramic views of the island and beyond. If you prefer to stay closer to sea level, the snorkeling here is out of this world. The island is surrounded by the southernmost coral reef on the planet, which means you'll encounter vibrant fish, coral, and even sea turtles.

And here's something quirky yet fascinating: Lord Howe Island is one of the few places where you can see the rare woodhen, a bird that was once thought to be extinct.

Pro Tip

Travel between September and May for the best weather and optimal snorkeling conditions.

2. Flatey Island, Iceland

If peace and quiet sound like heaven, then Flatey Island in Iceland is your dream destination. This small island in Breiðafjörður Bay has no cars and only a handful of buildings, giving it an old-world charm that feels like stepping back in time.

Why It’s Special

Flatey is all about simplicity. Imagine strolling through colorful, historic cottages while the calls of seabirds echo in the background. Speaking of birds, this island is a haven for puffins, Arctic terns, and other fascinating species, making it a birdwatcher’s paradise.

The island’s main building is a small library, which holds the oldest books in Iceland. Between the library, the slow pace of life, and the breathtaking views of the surrounding fjords, there's something almost magical about Flatey.

Pro Tip

Flatey is a seasonal destination and is best visited during the summer months. Most ferries stop here between June and August.

3. Socotra, Yemen

Remote, mysterious, and otherworldly, Socotra is unlike any place on Earth. Located in the Arabian Sea, about 220 miles off the coast of Yemen, this island is often referred to as the “Galápagos of the Indian Ocean.”

Why It’s Special

Socotra is home to bizarre and striking landscapes you won’t see anywhere else. Its dragon’s blood trees, with their umbrella-like canopies, look straight out of a science fiction movie. But it’s not just the trees that are unique. Around one-third of Socotra's plants and animals are found nowhere else.

Beyond its wild beauty, Socotra boasts crystal-clear waters, white sand beaches, and rugged mountains perfect for hiking. Despite its remoteness, the island is increasingly gaining attention from intrepid travelers looking for a unique adventure.

Pro Tip

Be prepared for limited accommodations and facilities. This island is all about raw, unfiltered nature, so plan accordingly. A guided tour is the best way to explore Socotra.

4. Isle of Eigg, Scotland

The Isle of Eigg is small in size but big in character. Located in Scotland’s Inner Hebrides, this tiny island has a dynamic history, a close-knit community, and an innovative approach to sustainability.

Why It’s Special

Eigg is entirely community-owned and powered by renewable energy. It’s a pioneer in eco-tourism, making it a great choice for conscious travelers. The island itself is ruggedly beautiful, with rolling hills, dramatic cliffs, and stunning views of the Atlantic Ocean.

One of the highlights is the Singing Sands, a beach that produces musical sounds when you walk on it. Pair that with a visit to the island's cultural sites, like the ancient Kildonan Church, and you have the recipe for a truly enchanting getaway.

Pro Tip

Don’t forget your hiking boots. Trails like An Sgurr will reward you with some of the best views in Scotland.

5. Ilha das Flores, Brazil

Off the northeastern coast of Brazil lies Ilha das Flores, a small island that feels like a secret paradise. Despite its beauty, it’s a destination most tourists haven’t discovered yet.

Why It’s Special

Ilha das Flores is best known for its mangrove forests and sparkling lagoons. Kayaking through the mangroves is an unforgettable experience, as you’ll spot various birds and aquatic life along the way.

The island is also close to a massive coral reef system, making it a haven for snorkeling and scuba diving enthusiasts. Combine that with the warm, tropical climate, and you’ve got a recipe for relaxation.

Pro Tip

Visit between November and March to enjoy sunny weather and calm seas.

6. Ulleungdo, South Korea

Nestled in the East Sea, Ulleungdo is a volcanic island that’s as beautiful as it is intriguing. Sometimes called the “Mysterious Island,” Ulleungdo offers a mix of natural splendor and cultural discoveries.

Why It’s Special

Ulleungdo’s dramatic cliffs and waterfalls create some of the most striking landscapes you’ll find in South Korea. Hiking trails crisscross the island, offering rewarding views of the surrounding waters and unique volcanic formations.

The seafood here is unbeatable. Try the island’s fresh squid dishes or share a meal with locals to experience true Korean hospitality. And if you’re into quirky attractions, don’t miss the Dokdo Museum, dedicated to Korea’s easternmost islets.

Pro Tip

Spring and fall offer mild weather and fewer tourists, making them ideal seasons to visit.
