This is a meticulously researched book where all the walks are well described and, of those I tried, very accurate. There are also little anecdotes and "off trail" comments that make it a lively, easy read.
However, the book does have some drawbacks. Most important is the fact that to get to the start of many of these walks involves driving off-road, sometimes for quite long distances and often on poor quality tracks. Considering that many users of this book will be in a hire car, this is quite a big consideration.
Following the road directions to the start of walks means some local knowledge of where the villages are is helpful, or at least a close-scale map of the area.
The maps for the walks are quite poor, just a red line overlaid on a fuzzy reproduction of an existing map.
And a minor annoyance: the author describes the Axarquia as "one of the world's great places". I can only say he hasn't travelled much! It's nice enough - spectacular in a few small pockets - but hardly world-class in terms of scenery and walking.
Overall, this book - like the others in the series - falls short of the similar Sunflower guides in terms of presentation, but it's still a worthwhile buy if you intend to do more than just sit on the beach in this part of Spain.
