I used this map every day in Tenerife over the past week and found it great and up-to-date. Navigating in Tenerife is fairly easy - moreso with this map. It does feature some forestry-type roads (i.e ones you wouldn't want to tackle in a rental car or poor weather), but these are clearly marked as secondary roads. Incidentally, the TF-436 (Masca) on the west is a great drive (if you like windy, Italian-type roads with amazing cliffs and more switchbacks than you can shake a stick at). It would be great if it was pre-folded in a logical manner, as my navigator tore his hair out trying to fold it again each time. This meant it wore out quite quickly. Also, it would have been great if it came in a plastic cover. However, for the price it's great value.
