I have recently acquired the 6th and latest edition of Noel Rochford’s Landscapes of Gran Canaria, published by Sunflower Books. This has triggered some small updates to the Gran Canaria page. Especially note that for my walk 4 (walk 19 in the book), the decent directly down into Los Palmitos has been fenced off and is now impassable. You can actually see this on Google Street View where the lane coming from the north into the park’s parking lot is barred and bolted. I would not suggest climbing the fences as a good option.
