When the Camino del Rey opens in January or February 2015, I think it will be fair to say that the whole area will be inundated by people wanting to see and walk the newly renovated kings pathway. This provokes a few questions, how on earth are the numbers of people walking this path going to be controlled? How much will it cost? How will one get a permission to be able to enter? Right now these questions go mostly unanswered.
Although unofficial, (and as yet without a website) there is an organisation in El Chorro with a facebook page that is taking peoples details in order to create a database to present to the authorities before the path opens. Looking at the comments on this page there are already thousands of people adding their names to the list. If you want to add your name to the list, go to the facebook page and send them a message (of course, you do need a facebook account). In the message put how many people and roughly the date you want to visit. This information will help the guys working over in El Chorro to see what kind of impact the opening will have and how to overcome the access issues.
The rumor is that access for the first 2 months will be free of charge and there will be a limit of 500 people per day to walk the Caminito del Rey which will mean that weekends and bank holidays will be full probably all year long…. My advice, when it finally opens, is to stick to weekdays
