The Škocjan caves are out of this world. We knew they were a UNESCO site, so we wanted to check them out while in Slovenia. There’s no good public transport to the caves so we decided to take a tour and we sure didn't regret it. It saved us time as the guide knew all the ins and outs and we didn't have to wait anywhere or search for parking, which was an especially precious bonus in Piran. The town is off limits for cars, so we really recommend you book this trip. The guide knew so much about the area. You really can’t go wrong with this package!
