Tickets are now available right up to the end of January 2017 for walking the Caminito del Rey.
There is also now a guided tour option on the booking page and as all the information is in Spanish, One must assume that the guided tour is in spanish as well.
Presumably the web site and the guided tours will be correctly published and supplied in at least English in the near future. As of now it seems the emphasis is on the Spanish language even though a large proportion of visitors are international.

I’ve been living in this lovely area of Western Andalucia for the last 20 years or so and dedicate most of my time to the running of English language tourist information websites for the towns of Cádiz, Ronda, Grazalema, the famous or infamous Caminito del Rey, and also Wildside Holidays, which promotes sustainable and eco-friendly businesses running wildlife and walking holidays in Spain.
