In central Istria, a 10th-century castle sits above a 130-meter karst abyss, with a cave system that inspired Jules Verne's novel. Monthly markets continue a tradition from 1539.
Pazin sits on limestone cliffs above a 130-meter deep karst abyss in central Istria. You'll find a medieval castle perched at the edge of the chasm, where the Pazinčica River vanishes into underground caves. Jules Verne set his novel "Mathias Sandorf" in these caves, which you can explore with guides or view from above while zip-lining across the gorge. The castle now houses the Ethnographic Museum with its collections of 19th-century farming tools, wooden furniture, and local textiles.
Exploring the Pazin Cave
Walk 270 meters underground through the Pazin Cave system to see three siphon-shaped lakes: Malo, Mitrovo, and Veliko, where the Pazinčica River continues its journey. Join a three-hour guided spelunking tour to learn about the limestone formations and local legends. Follow the marked trail at the cliff base to spot oak and hornbeam trees while reading information panels about the karst landscape. For a different perspective, take the four-line zipline course from Hotel Lovac Green terrace, crossing directly above the cave entrance.
The Medieval Castle Complex
Built in 983, Pazin Castle's defensive walls reach three meters in thickness. A semi-circular tower, added in 1463, strengthens its fortifications. Inside the Ethnographic Museum of Istria, you'll see wool-spinning wheels, olive presses, and carved wooden chests from the 1800s. Visit the City Museum of Pazin in another section to examine Stone Age tools, Roman coins, and documents from the Venetian period.
Monthly Fair and Cultural Events
Walk through the town promenade on the first Tuesday each month to browse stalls of local cheese, wine, olive oil, and handmade crafts at the Pazin Fair, a tradition since 1539. In June, the Days of Jules Verne festival brings "Mathias Sandorf" to life with street performances and themed tours of the castle and cave system.
Getting Around Istria
Take direct trains from Pazin's station to Zagreb, Pula, Buzet, and Ljubljana. Buses run frequently to Rovinj (40 minutes) and Poreč (45 minutes). Drive the E751 highway to reach Trieste or take the A8 motorway to Rijeka. Most Istrian towns lie within a one-hour radius by car.
Climate and Best Time to Visit
Daytime temperatures in winter average 5°C, often with morning fog in the old town. Spring and fall bring 15-20°C weather, ideal for cave tours and hiking. Summer temperatures reach 30°C, but the cave maintains a steady 14°C year-round, making it a good activity during hot afternoons.
