2.Postojna Cave & Predjama Castle from Koper

★★★★★★★★★★4.5 · 46 reviews · 5 hours (approx.) · from $139

From Koper, your driver-guide takes you to Postojna Cave for an electric-train ride and guided walk through its 10°C underground halls. You then visit Predjama Castle, built into a 123-meter cliff. Pickup is available from hotels, the cruise terminal, bus and train stations. Guides such as Tina and Ernest have received especially warm praise.

“Cave and castle were beautiful. It's a bit of a drive too both and it felt like we were rushed at both sites. We still had enough time though to enjoy both sites. Caves were a bit chilly when on the train. Shorts and light jacket is more than enough if your from a cooler climate.”

3.Tour to Postojna and Predjama Castle from Koper

★★★★★★★★★★5.0 · 45 reviews · 5 hours (approx.) · from $118Best value

Travel from Koper by air-conditioned bus or minibus with a driver-guide such as Stanley, Luka, Andi, or Rastka. Ride an electric train into Postojna Cave, walk through huge chambers for about 45 minutes, then stop for photos at Predjama Castle. Cave admission and port pickup are included, but castle entry is not.

“The Caves are beautiful and huge. An electric train takes you in and out. In between you have a 1 hour walking tour and 3 tops with an English speaking host. The walks are on good solid concrete or up steps but are not pushed. Bring a camera that takes good shots with little light. You canNOT take flash pictures but can take camera shots and videos without the flash. It is wonderful!!!”

4.Postojna Cave & Photostop Predjama castle – Group Tour from Koper

★★★★★★★★★★5.0 · 35 reviews · 5 hours (approx.) · from $153

From Koper Cruise Terminal, ride an air-conditioned van to Postojna Cave, enter by electric train, and walk through its cool underground halls with a local guide. Your English-speaking escort, possibly Yuri, Mateja, Marina, or Neva, handles timing and transport. The tour ends with a 15-minute photo stop at Predjama Castle, not an interior visit.

“Both the cave and castle were wonderous experiences. Must sees. Chose my cruise because it would stop in Koper, Slovenia so that I could take this tour. The van was comfortable and the tour guides friendly. Both the cave and castle had self-guided options.”

From finding him as we disembarked (super easy) to the drive out to the cave and castle (good info on Slovenia history and culture), to a couple quick extra stops on the drive back because we were ahead of schedule. Thanks Matt and Koper Tours! You made our first time experience in Slovenia memorable.”
