While millions flock to Hawaii, the Maldives, and Caribbean hotspots, some of the world’s most spectacular islands remain virtually untouched by mass tourism. These hidden gems offer pristine beaches, unique wildlife, and authentic local cultures, all without the crowds and commercialization that often plague popular destinations.
From remote Arctic outposts to tropical paradises tucked away in less-travelled regions of the ocean, these islands provide experiences that feel like stepping into an undiscovered world. Here is a list of 20 secret islands that most travelers never even know exist, each offering something truly special for those willing to venture off the beaten path.
Socotra Island, Yemen
Socotra feels like stepping onto an alien planet rather than visiting Earth. About one-third of its plant species exist nowhere else on the planet, including the bizarre dragon’s blood trees that look like giant umbrellas sprouting from rocky terrain.
The island sits about 230 miles off Yemen’s coast, making it incredibly isolated and difficult to reach during political instability.
Faroe Islands, Denmark
These 18 rugged islands between Iceland and Norway offer some of Europe’s most dramatic landscapes without the tourist hordes. Grass-roof houses dot villages with populations smaller than most high schools, while massive cliffs drop straight into the North Atlantic.
The weather changes faster than a teenager’s mood, but that unpredictability adds to the raw beauty.

Solovetsky Islands, Russia

Most visitors arrive by boat during the brief summer months when temperatures actually climb above freezing.
Lord Howe Island, Australia
This UNESCO World Heritage site limits visitors to just 400 at any time, keeping it refreshingly uncrowded. The island sits about 370 miles northeast of Sydney and boasts the world’s southernmost coral reef.

The island sits just 70 miles southwest of Adelaide, yet it feels completely removed from city life.
Lofoten Islands, Norway

Most of the island remains pristine native forest, perfect for hikers seeking true wilderness.
São Tomé and Príncipe
This tiny African nation consists of two main islands in the Gulf of Guinea, offering pristine rainforests and empty beaches without resort development. Cacao plantations cover volcanic slopes, and Portuguese colonial architecture adds charm to small towns.
The islands sit about 180 miles off Gabon’s coast, making them one of Africa’s least visited countries.
Jeju Island, South Korea

The island’s temperate climate and diverse ecosystems earned it UNESCO World Heritage status.

Vanuatu
This Pacific archipelago of 83 islands offers active volcanoes, pristine coral reefs, and some of the world’s most diverse cultures packed into a relatively small area. Each island maintains distinct traditions and languages, with some villages still practicing ancient customs.
The main islands are easily accessible by air, but the outer islands require boat travel and local connections.
Sark, Channel Islands
One of the last feudal states in Europe, this car-free island between England and France operates like a medieval time capsule. Horse-drawn carriages and bicycles provide the only transportation, while oil lamps light many buildings after dark.
The island measures just 2 miles long and 1 mile wide, making it perfect for a peaceful walking retreat.
Palawan, Philippines
Often called the Philippines’ last frontier, Palawan stretches nearly 270 miles between the South China Sea and the Sulu Sea. Underground rivers wind through limestone caves, while pristine lagoons hide between towering karst formations.

Tasmanian devils have become increasingly rare due to a contagious facial tumor disease, but wildlife sanctuaries offer chances to see these unique marsupials.
Flores, Portugal
The westernmost island in the Azores archipelago feels like the edge of the world, with dramatic crater lakes and fewer than 4,000 residents. Two massive lakes occupy ancient volcanic calderas, creating mirror-like surfaces that reflect surrounding cliffs.
The island’s isolation means traditional Portuguese culture remains largely unchanged.
Chiloé Island, Chile

When Isolation Becomes Discovery

Each destination offers something that mainstream tourism hasn’t yet commodified, whether it’s untouched nature, authentic culture, or simply the rare pleasure of having paradise mostly to yourself.

In an age when social media makes every location feel familiar before you arrive, these islands offer the increasingly rare gift of true surprise.
