The highlight for many visitors is the 2-hour guided tour of the Kocjan Caves, a UNESCO World Heritage Site. The caves boast a majestic underground river gorge filled with colorful stalactites and stalagmites. You’ll walk through underground halls, marvel at limestone pools, and observe waterfalls that add to the cave’s mesmerizing atmosphere.
What truly sets the Kocjan Caves apart is their immense underground canyon, making them one of the most famous subterranean sights globally. Visitors often comment on the varieties of formations—from curtains to limestone pools—and the volume of the canyon, which makes the setting feel expansive and awe-inspiring.
Note: Inside the caves, there are 500-600 steps, and slippery floors mean proper footwear is advisable. As photo restrictions may apply due to dark and slippery conditions, focus on the visual experience rather than capturing every moment on camera.

Following the caves, the tour stops at Socerb Castle for a 30-minute visit that offers breathtaking views of the Slovenian coast and the Gulf of Trieste. The castle, a ruin perched high on a cliff, has roots dating back to Illyrian times. Its vantage point provides a perfect backdrop for photos and a chance to absorb the surrounding landscape.
Visitors appreciate the photo opportunities and the sense of history that the castle ruins evoke, making it a peaceful, scenic break before heading to the coast.
The final part of the trip takes you to Piran, where you get around 3.5 hours to explore. The town’s narrow streets are lined with beautiful houses, churches, and squares that showcase Venetian influence. Walking through this coastal town feels like stepping back in time, with colorful facades and lively sea breeze.
Visitors enjoy having time to wander freely, with options to sit at a cafe, try local food, or shop for souvenirs. The guide often points out notable sights like the Piran City Wall and shares tips for finding the best seafood or gelato.
