Istria is Croatia's largest peninsula, jutting into the northern Adriatic Sea and bordering Slovenia and Italy. Known as the 'Croatian Tuscany,' it blends Roman heritage, Venetian architecture, medieval hilltop villages, and a world-class culinary scene centered on truffles, olive oil, and indigenous wines.
Top day trips
Handpicked excursions within easy reach.
Venice, Italy
The most iconic day trip from Istria — a high-speed catamaran to La Serenissima. The Venezia Lines catamaran typically departs Rovinj at 08:00 and Poreč at 08:30, arriving Venice by noon. You get 5-6 hours in Venice (St. Mark's, Grand Canal, Rialto) before the return crossing at 17:00. A once-in-a-lifetime experience easily combined with a stay in Istria.
Highlights: St. Mark's Square and Basilica · Grand Canal · Rialto Bridge · Vaporetto water bus rides · Venetian cicchetti (tapas)
Trieste, Italy
Trieste is one of Europe's most atmospheric and underrated cities, just 90km from Poreč. A former Habsburg imperial port and multi-ethnic crossroads, it has stunning coffee culture (Illy coffee was founded here), grand neo-classical architecture, the Castello di Miramare on a sea cliff, and excellent seafood. James Joyce lived and wrote in Trieste. A surprisingly rewarding and easy day trip.
Highlights: Piazza Unità d'Italia (largest sea-facing piazza in Europe) · Castello di Miramare and park · Coffee culture (Caffè San Marco) · Rione di Cavana (old town) · Grand Canal area
Plitvice Lakes National Park
Croatia's most visited natural attraction — 16 interconnected turquoise lakes connected by hundreds of waterfalls in a UNESCO World Heritage Park. It is a long day trip from Istria (5-6 hours driving total) but absolutely worth it. The combination of emerald green and blue lakes, travertine waterfalls and forest scenery is extraordinary. Visit early morning or in spring/autumn to beat summer crowds.
Highlights: Veliki Slap (Big Waterfall) — Croatia's highest at 78m · Gornja and Donja Jezera (upper and lower lakes) · Electric boat across lake · Wooden boardwalks over falls
Opatija and Kvarner Riviera
Opatija is the jewel of the Kvarner Riviera — a belle époque resort built by Austrian aristocracy in the 1880s, with grand Habsburg-era hotels, a beautiful seafront Lungomare promenade lined with magnolias, and a genteel old-world charm that feels like a Croatian Baden-Baden. Combine with a quick stop in Rijeka, Croatia's third city and current cultural hub.
Highlights: Lungomare coastal promenade (12 km) · Habsburg grand hotels (Kvarner, Imperial) · St. Jacob beach · Villa Angiolina park · Rijeka Carnival (world's third largest — February)
Ljubljana, Slovenia
Slovenia's charming and compact capital is a surprisingly easy day trip from northern Istria, just 150km from Poreč. Ljubljana's Baroque old town, riverside café culture, Ljubljana Castle on a hill above the city, and vibrant food market make it a delightful contrast to Istria's coast.
Highlights: Ljubljana Castle and funicular · Dragon Bridge · Open Market (central market) · Triple Bridge and riverside promenade · Metelkova alternative culture district
Brijuni National Park
A wonderful day trip from Pula or Rovinj to Istria's own island national park. Brijuni archipelago offers an extraordinary mix of Roman ruins (Villa Rustica), dinosaur footprints on stone, Tito's personal residence and state collection of exotic animals gifted by world leaders, a safari park with zebra and llama, and beautiful swimming in the national park waters.
Highlights: Roman Villa Rustica ruins with mosaics · Dinosaur footprint site · Tito's Villa and museum · Safari park with exotic animals · St. German Byzantine fort ruins · Swimming from island beaches
Motovun, Hum and Interior Istrian Hill Towns
A perfect full-day loop through the Istrian interior visiting the region's most atmospheric hilltop towns. Start in Motovun for morning mist views and Venetian walls, continue to truffle-rich Livade for lunch at Restaurant Zigante, visit Glagolitic Alley walk from Roč to Hum (world's smallest town), then Buzet for afternoon wine before returning to the coast.
Highlights: Motovun ramparts and valley views · Mirna river valley truffle forests · Glagolitic Alley sculptures · Hum — world's smallest town with 17-30 residents · Buzet old town and truffle shops
