The idea of escaping to a far-off island has a special kind of magic. But while most people dream about places like Hawaii or the Maldives, there are dozens of smaller, under-the-radar islands that are just as stunning but far less crowded. These hidden gems often offer unique cultures, unspoiled landscapes, and unforgettable experiences waiting to be discovered.

Whether you’re someone who loves quiet beaches, lush forests, or vibrant local traditions, these lesser-known islands have something unique to offer. They might not show up on most travel brochures, but that’s what makes them feel like true hidden secrets. Here are 10 small islands that promise adventure, relaxation, and an experience you won’t forget.

1. Isle of Coll (Scotland)

Tucked away in Scotland’s Inner Hebrides, the Isle of Coll is like stepping into another world. Known for its rugged beauty and peaceful vibes, this small island is the ultimate getaway for nature lovers. Its white sandy beaches are so pristine you’d almost think you’re in the tropics, but the cool breeze and dramatic cliffs remind you this is unmistakably Scotland.

Coll is also a designated Dark Sky Island, meaning it’s one of the best spots in the world for stargazing. On a clear night, you can see a dazzling array of stars, planets, and maybe even the Milky Way.

Why it feels like a secret escape: Its remote location and tiny population mean you’ll likely have the beaches and trails all to yourself.

2. Flatey Island (Iceland)

Flatey, or “Flat Island,” is a small spit of land in Iceland’s Breiðafjörður Bay. Its name makes sense, as the island is almost completely flat, but don’t let that fool you into thinking it’s boring. Colorful traditional houses dot the landscape, and the island is a haven for seabirds, including puffins.

Life on Flatey is slow and simple, with no cars allowed and just a handful of residents. Visitors come here to soak up the tranquil atmosphere, enjoy fresh seafood, and take in breathtaking views over the fjord.

Why it feels like a secret escape: It’s like stepping back in time to when life was simpler, with no rush or noise to interrupt the peace.

3. Jost Van Dyke (British Virgin Islands)

If you could imagine what paradise looks like, you’d probably picture something similar to Jost Van Dyke. This tiny island in the British Virgin Islands is famous for its turquoise waters, white beaches, and laid-back vibe.

Despite its popularity among sailing enthusiasts, Jost Van Dyke still has a hidden-gem feel. You can sip a piña colada at a beachside bar, hike up green hills for stunning views, or take a dip in the island’s natural sea-foam Jacuzzi, known as the "Bubbly Pool."

Why it feels like a secret escape: It has all the beauty of the Caribbean without the crowds of larger resort islands.

4. Lord Howe Island (Australia)

Lord Howe Island might just be Australia’s best-kept secret. Located about 370 miles off the mainland, this tiny island is home to just 400 visitors at any given time, thanks to strict tourism limits designed to protect the environment.

The island is a dream for outdoor enthusiasts. You can snorkel around coral reefs, hike to the top of Mount Gower for panoramic views, or simply relax on one of the island’s crescent-shaped beaches. It’s also home to unique wildlife like the Lord Howe Island woodhen, which can’t be found anywhere else.

Why it feels like a secret escape: Its untouched beauty and small crowds make it feel like a private island retreat.

5. Île de Porquerolles (France)

France isn’t just about Paris and the Riviera. Île de Porquerolles, one of the Îles d’Hyères along the French Mediterranean coast, is the perfect mix of charm and tranquility. No cars are allowed on the island, so visitors get around by bike or on foot.

The beaches here are nothing short of perfection, with calm, crystal-clear waters perfect for swimming or paddleboarding. Inland, you’ll find vineyards, olive groves, and fragrant pine forests. It’s like stepping into a postcard, but with fewer crowds than other Mediterranean hotspots.

Why it feels like a secret escape: Its car-free, relaxed lifestyle offers a break from the hustle and bustle of mainland France.

6. Monuriki Island (Fiji)

If Monuriki looks familiar, it’s because this small island in Fiji starred as the filming location for the movie Cast Away. While it might not have Tom Hanks and Wilson waiting for you, it does have stunning beaches, towering volcanic rocks, and waters filled with colorful fish.

You’ll need a boat to reach Monuriki, but the effort is well worth it for views of untouched wilderness. Snorkeling in the surrounding coral reefs is a must, and you might even see sea turtles gliding along the ocean floor.

Why it feels like a secret escape: Its remote, uninhabited nature makes you feel like you’ve discovered your own private paradise.

7. Ilha Grande (Brazil)

Off the coast of Rio de Janeiro, Ilha Grande is a lush island that feels worlds away from the busy streets of the city. Covered in rainforests and surrounded by golden beaches, it’s an outdoor lover’s paradise.

The island has a no-car policy, which means you’ll explore it on foot, by bike, or by boat. Popular activities include hiking through dense jungle to hidden beaches, swimming in pristine lagoons, or snorkeling among vibrant coral reefs.

Why it feels like a secret escape: Its car-free environment and secluded beaches make it feel like a hidden oasis.

8. Caye Caulker (Belize)

Caye Caulker is a tiny island off the coast of Belize that captures the true meaning of “island time.” Its motto is literally “Go Slow,” and that’s exactly the attitude you’ll adopt when visiting this laid-back slice of paradise.

The island is perfect for snorkeling or scuba diving, with the Belize Barrier Reef just a short boat ride away. On land, enjoy fresh seafood, colorful murals, and a chilled-out atmosphere that’s impossible not to love.

Why it feels like a secret escape: Its slow pace and friendly vibe make it feel like a Caribbean escape without the touristy hustle.

9. Vis Island (Croatia)

While Croatia’s coast is no secret, the island of Vis remains a hidden gem compared to its more famous neighbors like Hvar. Vis is the furthest inhabited island from Croatia’s mainland, adding to its mysterious allure.

Its beaches are rocky and secluded, and the island is dotted with charming villages where you can enjoy local wines and seafood. A visit to the Blue Cave, a glowing sea cavern accessible by boat, is an absolute must.

Why it feels like a secret escape: Its remote location and lack of large resorts make it feel authentically Croatian.

10. Lopud Island (Croatia)

Another Croatian gem, Lopud is part of the Elaphiti Islands near Dubrovnik. This peaceful island is car-free and attracts visitors looking for serenity and unspoiled beauty.

Its beaches are among the best in the region. Šunj Beach is famous for its soft sand and calm, shallow water, making it perfect for families. Whether you’re hiking through its forested interior or soaking up the sun by the sea, Lopud has a magical sense of calm.

Why it feels like a secret escape: Its tranquil vibe and lack of cars make it a refreshing contrast to bustling Dubrovnik.
