This book can give you a great walking holiday in Gran Canaria - a destination most Brits avoid, prefering La Gomera.(German walkers, however, seem to go to Gran Can in great number). The walks are well researched and link well with the good quality bus service on the Island, though they do assume that you are in one of the main towns (Las Palmas or Play del Ingles, which both struck me as quite horrid) so if you stay in a small village they may not link up with the busses quite so well. I visited the South in February, when it was green and the North was shrouded in mist, though later in the year I think the North can be green and the South arid. The North has most of the larger villages and the South the more dramatic, non-european, scenery. In wintertime there is a chance of extremely heavy,semi-tropical rainfall - so strong that it will cause landslides that leave roads unpassable for several months. (The authorities there said that this rain is a result of climate change).
I also took a rival publication, from the Rother walking guide series, but mostly used the Sunflower book as it has so much more detail and is more practical - for example the Rother guide seems to assume that you can afford taxis to out of the way places, often for both ends of the walk,but taxis are expensive in Gran Can - 35 euros from San Matteu to San Bartolome, about 12 miles. I found some of the walks quite arduous, though in a way this was welcome - another Sunflower guide I had used earlier had been too easy throughout. I warn against one walk, to the Barranco de la Mina, in wintertime - with the recent rain and the spray from the waterfalls, the steep path up the ravine was really treacherous. That said, I will be happy to base future holidays on books by Noel Rochford, the author of this tome.
