Cave tours are in groups and take around one hour. The temperature inside is 20ºC with humidity at 80%. The route is 1,200 metres long and up and down, in total, there are some 250 steps. Sensible footwear is recommended because in places the cave floor is wet. Pushchairs are not recommended.
The live concert lasts 10 minutes and is played by a quartet of musicians. This is followed by a light show imitating the sunrise of the sun over the lake. Then there is an opportunity to take a short boat trip across the lake or to continue on foot across the bridge.
Inside the caves filming and photography are prohibited as are animals, with the exception of guide dogs. You are asked to follow the instructions of the staff at all times.
