According to the already posted pictures, I expected more. In 15 minutes the walk is completed, including stops for pictures. The €5 are acceptable because it must have been a lot of work to install all those walkways and to maintain them. I would call this sight "alright" and if you are in this area, it is something to do. Also the town is worth seeing and it has an exit from the motorway. Parking could be a bit of a hassle and it will cost more then average but still not too bad. In the summer it is probably better to walk through there because of the cooler climate (mountain, running water). For me this was a one time event. Many stairs to walk up and down which means not handicapped friendly but it would be very hard do do giving the circumstances.
