A live guide speaks English or German; private and group options are both available.Is it for me?Choose the group tour if you're arriving at the cruise terminal alone or with one or two others and want to share the cost; pick the private option if you're traveling as a family or small group and prefer your own schedule and guide. Both cover the same four cities and the two hours in Piran—the difference is who you travel with and how the guide's attention is divided.Free cancellationTravelers' pickBest valuefrom€ 31View ›
