I recommend you to visit. The place is magical. But it's useless to be there without a guide. We were very lucky with the guide: we had the opportunity to ring the bells of an ancient bell tower, put candles in a 19th-century church, try ourselves as a ferryman and listen to how the first lock is arranged
I didn't like it at all. Nobody really cares. It is clear that money is needed for the maintenance of the park. Everything is overgrown with grass, except for the entrance group. Two minutes and I went around everything I could.
