Most travelers know Denmark for Copenhagen’s colorful canals or Aarhus’s creative energy—but did you know that Denmark is actually made up of over 400 islands? And many of them are secret escapes hiding just beyond the tourist trail. As someone who’s spent years living in and exploring this northern gem, I can tell you: the real magic begins when you venture off the mainland.
In this blog, I’m pulling back the curtain on Denmark’s secret islands—those tranquil, postcard-worthy spots that even many Danes don’t talk about. Whether you’re craving serene beaches, local heritage, or just the joy of island-hopping on quiet ferries, this guide will take you deep into the best of hidden Denmark.
So let’s get lost—on purpose.
🏝️ 1. Ærø: The Fairytale Island You’ve Never Heard Of
This isn’t your average Danish village. Ærøskøbing, the main town on Ærø Island, looks like it was pulled straight from a storybook. Think cobblestone streets, color-washed houses, and blooming roses around every corner. It’s not just quaint—it’s deeply Danish.
I biked the entire island in a day, passing sheep-filled fields, old lighthouses, and hidden beaches where I was completely alone. Ferries leave from Svendborg and Fynshav, and in summer, Ærø becomes a peaceful haven for artists, couples, and slow-living seekers.
How to Get There:
Ferries depart regularly from Svendborg on Funen. Biking is highly recommended, and rentals are available near the ferry port.
Pro Tip:
Visit in spring or early autumn to enjoy the island’s charm without summer crowds.

🌊 2. Samsø: Denmark’s Green Island Pioneer
Samsø isn’t just charming—it’s famous for being 100% powered by renewable energy. You’ll feel it in the air: clean, crisp, and fresh off the Kattegat Sea. The island is known for its organic farming, open skies, and quiet coastal walks.
Explore the sleepy harbor town of Ballen, grab fresh strawberries from roadside stands, and hike up to Issehoved for sweeping views. Even in peak season, Samsø feels slow-paced and local.
How to Get There:
Take the ferry from Hou (Jutland) or Kalundborg (Zealand). It’s a short, scenic ride.
Pro Tip:
Don’t miss the local Samsø potatoes—arguably the best in Denmark.

🐚 3. Læsø: Salt, Saunas & Secluded Shores
Læsø sits way up in the Kattegat Sea, and it’s unlike anywhere else in Denmark. This island is famous for its sea salt—harvested using medieval techniques—and its seaweed-roofed cottages.
When I visited, I stayed in a converted salt worker’s house and took a seaweed sauna right on the beach. It was weird, wonderful, and totally rejuvenating. The beaches here are some of Denmark’s best-kept secrets.
Must-Do Experiences:
- Seaweed sauna sessions
- Læsø Salt Works tour
- Beachcombing on Østerby strand

🛶 4. Tunø: No Cars Allowed
You won’t hear any engines on Tunø—cars aren’t allowed. Just bicycles, carts, and your own two feet. Located off the east coast of Jutland, Tunø is small, peaceful, and beloved by Danish families looking for a digital detox.
The hike around the island’s edge takes about two hours and offers dramatic sea views and wildflower fields. At night, the stars pop like nowhere else. It’s one of the most peaceful places I’ve ever slept.
Must-Have Info:
- Ferries depart from Hou (near Odder)
- There are no ATMs, so bring cash
- No cars allowed—plan to walk or cycle

🌿 5. Fur: Denmark’s Fossil Island
Fur is geologically special—you’ll find clay cliffs, fossil-rich rock formations, and small artisan breweries all on the same island. It’s a favorite among Danish geology buffs and families who come here to dig for ancient fish fossils.
Even if science isn’t your thing, the natural beauty here is something else. Think high cliffs, crashing waves, and quaint rural lanes that end at small, windswept beaches.
Pro Tip:
Head to Knudeklint for the most photogenic cliff walks and fossil finds.
🍺 Explore Fur Bryghus for local beer tasting.
🚴 6. Fanø: Seals, Bunkers & Kite Buggies
Just a short ferry from Esbjerg, Fanø blends wide beaches with war history and wildlife. This is where you’ll see real seals lounging on sandbanks, WWII bunkers tucked in the dunes, and massive beaches perfect for biking and kite surfing.
The annual Fanø International Kite Festival is a blast of color in the summer sky—and totally worth timing your visit around.
Pro Tip:
Rent a fat-tire beach bike for the full Fanø experience.
🌺 7. Strynø: Tiny But Mighty
Located in the South Funen Archipelago, Strynø has just a few hundred residents—but what it lacks in size, it makes up for in heart. The island has an impressive Maritime Education Center and a laid-back, eco-conscious community.
I stayed at a local guesthouse and kayaked around the island with a group of friendly Danes. The sunsets here? Unreal.
How to Get There:
Catch a ferry from Rudkøbing on Langeland. Ferries are small but frequent.
