Sure thing Jurdy,
This is the site linking to the description of each walk, and the link to the calendar pdf is at http://www.xabia.org/a_pie.html - all the leaflets are available in English at any of the 3 tourist offices themselves though I can’t find the English versions online.
I should also add that the walk I did at the weekend, graded ‘medium’, was pretty heavy going to my mind. Not long, but more like a climb/scramble in places, where the path was actually a chain bolted to a cliff! I was glad I didn’t have the kids along with me or anything, and also I found the path markings somewhat intermittent and was very glad our Guia knew where she was going. Like everything else in Spain you are responsible for your own fitness and safety to a greater extent than you may be expecting, and get out exactly what you put in… the rewards being incredible, amazing views and experience..!
