The park and falls are amazing with many points with a great vista. Price is 10€, that is fair. There are 5 or 6 trails to follow. Some of them are disrupted and apparently the company that started to fix them is broke, because the improvement works have been abandoned, and should have been finished years ago. The 2 stars rating is because there is one of the trails, the 2nd if I am not wrong, that is pretty difficult with around 700 "stairs" and that can be done going up or down. Long story short, on the maps and on internet, you will find that you can do the trail in the direction you prefer and, when you are done, you will be able to take a bus to go back where you starded (and to you car). In reality this bus, or any other bus was non existent and you had to do the tough trail again if you wanted to leave. There were, in fact, many families with childrens and older people complaining about this, because nobody told them about this when they entered and asked for informations. A woman that we knew during the walk had to call an ambulance because she hurt her foot and wasn't, of course, able to do the trail back to her car. Apparently in september, the bus is active only on Saturday and Sunday, but with so many tourists still around in this season, they should tell you, or write somewhre this small detail. I personally asked the difficulty of thos trail when I started, and nobody mentioned to me that I would have been obliged to do it twice.
