Escape the crowds and discover Europe's best-kept island secrets

Introduction: Beyond Santorini and Ibiza—Europe’s Secret Isles Await

When most travelers dream of European island escapes, names like Santorini, Mykonos, Mallorca, or Capri typically come to mind. But in 2025, savvy explorers are ditching the mainstream hotspots for lesser-known gems—places where pristine beaches meet authentic culture, and tourism hasn't yet overwhelmed local life. These underrated islands offer exactly what modern travelers crave: authenticity, calm, and unspoiled beauty.

In this guide, we’ll take you beyond the brochures to explore 10 of the most underrated islands in Europe—each a perfect destination for those seeking something quieter, more meaningful, and infinitely more memorable.

1. Gozo, Malta

Often overshadowed by its bigger sister island, Malta, Gozo is where Mediterranean charm meets countryside peace. Known for its slow-paced lifestyle, rugged coastlines, and ancient temples, Gozo is a dream for both history buffs and beach lovers.

• Don’t Miss: Ġgantija Temples (older than the pyramids!), Ramla Bay, Xlendi Cliffs
• How to Get There: 25-minute ferry from Ċirkewwa, Malta

2. Nisyros, Greece

Tucked between Kos and Tilos in the Dodecanese chain, Nisyros is a volcanic island with a beating geothermal heart. Its dramatic caldera, traditional villages, and sparse crowds make it a photographer's paradise.

• Top Experience: Hike into the Stefanos Crater and feel the earth breathe beneath your feet
• Why It’s Underrated: Most tourists pass by en route to Kos

3. La Graciosa, Spain (Canary Islands)

Spain’s eighth Canary Island only received “official” island status in 2018. Car-free and mostly wild, La Graciosa is a haven of quiet beaches, dunes, and Atlantic serenity.

• Stay Simple: Rent a bike, pack a picnic, and enjoy total tranquility at Playa de las Conchas
• Reachability: Short ferry ride from Lanzarote

4. Isola di Procida, Italy

Italy's Bay of Naples has Capri and Ischia—but it’s Procida, the tiniest of the three, that steals hearts in 2025. With pastel-colored fishing houses, quiet harbors, and few international tourists, Procida is a cinematic escape.

• What to Do: Get lost in Marina Corricella’s backstreets, watch the sunset over Terra Murata
• Extra Tip: Go before cruise ships discover it

5. Kornati Islands, Croatia

Technically a national park comprising 89 islands, the Kornati Archipelago is the Adriatic’s best-kept secret. Accessible mostly by boat, it’s a wonderland of raw limestone, aquamarine waters, and sailing freedom.

• Best For: Island hopping, snorkeling, and off-grid sailing
• Insider Tip: Book a small-group sailing charter for a real escape

6. Hailuoto, Finland

Europe’s northern coasts rarely make island roundups, but Hailuoto is a treasure for nature lovers. Situated in the Gulf of Bothnia, this Finnish island is home to bird sanctuaries, pine forests, and untouched shorelines.

• Experience: Midnight sun walks in summer; frozen sea safaris in winter
• How to Visit: Free ferry from Oulu (year-round) or drive over the seasonal ice road

7. São Jorge, Azores (Portugal)

The Azores are gaining fame, but São Jorge remains relatively untapped. Known for its dramatic cliffs and “fajãs” (flat lava fields at sea level), this island is paradise for hikers and cheese lovers alike.

• Must-Try: Queijo de São Jorge, a tangy cow’s milk cheese aged in volcanic air
• Top Activity: Hike the Fajã da Caldeira de Santo Cristo trail

8. Leros, Greece

Far from the ferry routes of the Aegean giants, Leros is calm, traditional, and charming. With its neoclassical architecture and WWII history, Leros feels like a living time capsule.

• Don’t Miss: Climb to the Castle of Pandeli at golden hour
• Why Go Now: Still largely undiscovered—even in peak summer

9. Isle of Eigg, Scotland

Part of the Inner Hebrides, Eigg is community-owned and green-powered. It’s small (just 30 km²), but rich in wildlife, sea cliffs, and indie traveler spirit.

• Experience: Wild camping under the stars, whale spotting from the coast
• Eco Note: Entire island runs on renewable energy

10. Bozcaada, Turkey

An Aegean jewel with Greek roots and Turkish soul, Bozcaada charms with cobblestone alleys, boutique vineyards, and sun-drenched beaches.
