City(3)
Stop in Europe's greenest capital, where the Ljubljanica River, Jože Plečnik's bridges, and modern architecture create a city that was the European Green Capital in 2016. Explore the old town with its cobblestone alleys, the 11th-century castle, and the central market. Stop in this city where architecture, markets, and life create a vibrant atmosphere. Wander its streets, admire its monuments, and discover the local culture. The city combines tradition and modernity in a fascinating cultural mosaic.
Enter Piran through Tartini Square, the heart of the town, dedicated to the violinist Giuseppe Tartini, who was born in one of its Venetian houses. Climb the cobbled lanes up to the medieval walls and gaze down from above at the red rooftops and the Slovenian Adriatic. Visit St. George's Church, whose bell tower evokes St. Mark's in Venice, and stroll along the seafront promenade to the Punta lighthouse. Sample fresh fish at the harbor taverns and browse the markets where salt from the nearby Sečovlje salt pans is still sold.
Climb the hill of Ptuj, Slovenia's oldest town, where 2,000 years of history pile up along the Drava River. Founded as Poetovio in the 1st century BC, it preserves a 12th-century castle, Roman baths and medieval walls that still enclose the old town. Then head down to its squares and markets, where everyday life unfolds among Gothic and Baroque façades, and cross the pedestrian bridge to see the town's silhouette reflected in the water.
Natural(3)
Explore Lake Bled, a glacial lake in Central Slovenia, where an island is home to the 15th-century Church of the Assumption and the 11th-century castle perches atop the cliff. Walk the 6 km path that runs along the shore, paddle a kayak through the green waters, or cross to the island in a pletna, the traditional flat-bottomed boat rowed by local pletnarji. Climb up to the Ojstrica viewpoint at dawn: from there you can see the church floating among the peaks of the Julian Alps, an image that has inspired painters for centuries.
Watch the little electric train wind through 5 km of passages in Europe's most visited karst cave, right in the heart of the Slovenian Karst. You'll pass through halls with stalagmites and stalactites formed drop by drop, like the famous Brilliant, and cross bridges over the underground Pivka River. In the indoor aquarium you'll meet the proteus, the blind amphibian nicknamed the "baby dragon", which lives only in these waters. The temperature stays around 10 °C all year, so bring a warm jacket even in summer. From the entrance you can combine your visit with Predjama Castle, just a few kilometers away.
Camp at the mountain huts and climb Triglav, Slovenia's highest peak at 2,864 m. The ascent takes about 8 hours and crosses snowfields and glacier remnants, with open views over the Julian Alps. Along the way you'll see limestone rock formations, marmots, chamois and alpine flowers such as artemisia and the glacier buttercup. In Upper Slovenia, this mountain is also a national symbol: it appears on the country's flag.
