Yes, the article is correct, but it misses some nuances. After paying the hefty fee (it has always been free, and it still is if you are resident, at least up to 5 years ago it was) you can walk along a path that gets near the fall, but not inside it. If you pay even more to get a "guide" you can reach an observation point (the tunnel) where you can almost touch the water, and get a free shower in the process. All in the name of "safety" (aka: money) even if as far as I know only one suicide has been registered, in the 80's.
