I visited this WHS in May 2014. I wasn’t expecting much, especially because I knew that the best way the experience the underground canyon in the Skocjan Caves was to go for the 2hr guided tour with another 20 people and that no photography was allowed, not even without flash. The 2 hour guided tour takes place at 10am, 11:30am, 1pm, 2:30pm and 3:30pm. A huge group gathers in front of the ticket office and 3-4 guides lead the way to the entrance to Skocjan Caves. The walk and brief introduction takes around 15-20mins downhill and then each guide accompanies a group of around 20 people. The guide of my group was quite knowledgeable and made the visit quite interesting without giving too much detail. Photography is not allowed expressly to make sure that no flash photography takes place since it may damage the cave and to discourage people from loitering behind the rest of the group. I must admit I was naughty and I was the one to enter the caves last on purpose to take a couple of photos when I wasn’t under the guide’s strict supervision. I’m extremely happy with the few photos I took and the video with the deafening sound of the underground rapids. I didn’t keep the group waiting and I didn’t do any harm to the cave. After the 2 hour guided tour inside the caves, I did the 1.5hr self-guided tour which was included in my combined ticket. This trail gives you the opportunity to take photos and to admire the Skocjan Natural Park’s exterior beauty with waterfalls, limestone gorges and a great panoramic view opposite the church. Still it’s no substitute to the underground canyon experience!
