Very nice cave, about 2 km long. Great place for visit.
My tips:
1) Because there is cold inside, better to bring a jacket, no matter how hot it is outside.
2) The best way to arrive at 10:00 by car or by bus, because there are very few parking spots available and less people will be inside.
3) Leave your bag and huge things in the car, because before entering to the cave there are a 1 km upstairs.
