"Is it worth it? Yes in its way. If you’re looking for places to visit just out of curiosity or learn a thing or two, then go for it! You will also enjoy the ride until you reach the destination which is very beautiful! Enter the tunnel and start going back to time!! Enjoy and learn"
George Papadopoulos
"Beautiful cave experience! You start with a guided walk through the cave, then continue with a short boat ride, and afterward you can explore on your own at your own pace on the way back. Inside it’s a refreshing 9°C, so it feels nice and cool. You can also rent a blanket at the entrance for just €0.50 and return it afterward. You can pay by card, and there’s a small coffee place with a toilet (most likely you should buy something if you want to use it). Overall, a beautiful and unique experience!"
Ovidiu Sustic
"A very unique spot to visit in vicinity of Vienna which takes around 45-50 minutes to go through. You start walking into the cave and a guide explains you few things at various spots and at the end is a boat trip at lowest level (60m below ground level).
The ticket costs 18 euros per person. You have possibility to rent something warm (1 euro) to wear if you forgot to come dressed for lower temperature inside.
The boat trip is the best part. With lighting the whole thing looks fantastic.
You can find parking for car at the street next to it or go near the tennis place to park (beware to not park on Privatgrund of tennis place).
Overall worth the buck."
