Looking to escape the crowded streets of Paris, Rome, or London? In 2026, travellers are increasingly seeking cost-effective, lesser-known European destinations that promise rich experiences without the overwhelming tourist crush. According to Google Trends, searches for “hidden gems” have surged 122.6% in the past year, signalling a growing appetite for offbeat travel.

Riding this trend, Iglu Cruise has curated five underrated European cities that should be on every traveller’s radar this year. So, are you ready to explore Europe’s best-kept secrets?

Trenčín, Slovakia

1. Trenčín, Slovakia – A Medieval Gem in the Heart of Považie

Nestled along the picturesque Váh River, Trenčín is often called the “Pearl of the Považie” for good reason. This historic city, selected as one of two European Capitals of Culture in 2026, is set to dazzle visitors with art installations, live music festivals, and revitalised public spaces.

Why visit? Trenčín blends centuries-old architecture with a relaxed, authentic atmosphere. Explore the imposing Trenčín Castle perched atop cliffs, climb the City Tower for panoramic views, or sip coffee at a riverside café in Mierové Square. Families, couples, and solo travellers alike will find its charm irresistible.

Best time to visit: Late May to September. Music enthusiasts should not miss the Pohoda Festival in early July, Slovakia’s largest open-air music event.

Ghent, Belgium

2. Ghent, Belgium – The Fairytale City without the Crowds

Move over Bruges—Ghent is Belgium’s hidden jewel. With its winding canals, historic architecture, and vibrant student population, Ghent offers all the charm of a medieval city but with a modern, energetic twist.

Top attractions: Wander through the moated Gravensteen Castle, admire the legendary Ghent Altarpiece in St. Bavo’s Cathedral, and catch a magical sunset along the quays of Graslei and Korenlei.

Best time to visit: April to June and September to October for mild weather and vibrant parks. December is perfect for Christmas market lovers, as the city transforms into a winter wonderland.

Quimper, France

3. Quimper, France – Brittany’s Riverside Treasure

Tucked along the Odet River in Brittany, Quimper offers a quintessential French experience away from crowded tourist hubs. Leaning half-timbered houses, centuries-old city walls, and a thriving arts scene make it a must-visit.

Why go? Savor local cider, traditional crêpes, and Michelin-starred cuisine at Allium, Sao, or the cosy Ti-Coz. Explore Saint-Corentin Cathedral, pottery workshops in Locmaria, or take scenic boat rides along the river. Quimper also hosts the Festival de Cornouaille in late July, a vibrant celebration of Breton music, dance, and costumes.

Best time to visit: Late June to early September, especially if you want to soak in the festival atmosphere.

Turin, Italy

4. Turin, Italy – The Elegant Alpine Escape

Often overlooked in favour of Rome or Venice, Turin is a sophisticated gem in Italy’s Piedmont region. With Baroque boulevards, majestic palaces, and the stunning backdrop of the Alps, it combines elegance and culture with fewer tourists.

Highlights: Ride the glass elevator in Mole Antonelliana for panoramic Alpine views, sip the iconic Bicerin coffee in historic cafés, or tour the opulent Royal Palace of Turin. Turin has also been named the 2025 European Capital of Smart Tourism for its commitment to sustainability, accessibility, and cultural preservation.

Best time to visit: May, June, and September offer pleasant weather. December is ideal for the spectacular Luci d’Artista, a city-wide festival of light installations. Truffle lovers should plan for September, the start of Piedmont’s famed truffle season.

Poznań, Poland

5. Poznań, Poland – Colourful, Green, and Underrated

In western Poland, Poznań dazzles visitors with its rainbow-coloured houses lining the Old Market Square and lush green spaces that cover roughly 25% of the city. Often overshadowed by Kraków or Warsaw, Poznań remains one of Europe’s most underrated destinations.

Must-see spots: Stroll through Cytadela Park, unwind by Lake Malta, or cycle along the newly revamped Wartostrada, an 8-mile riverside recreational path. Don’t miss St. Martin’s Day on November 11, featuring parades, street parties, and local delicacies.

Best time to visit: May to September for outdoor activities, or November for a unique cultural celebration.
