I was hiking 8 days in the bernese alps, and this book is almost perfect for it.
almost - because all of its trips are day trips, but it has in its end a multi-day tours combination (from the 1 day tours) - one of them I did. (Meiringen - Griesalp).
The book is very detailed, and also points out to the problems in the extraordinary marked swiss paths.
one other thing I missed in it, is the lack of map (or drawing) with all the trips of that area.
last thing: since this is not the swiss pass route book, maybe there was a place for more details on the villages them self, and\or attractions in them. (the example I have in mind is the Trümmelbach waterfalls in Lauterbrunnen")
Overall - I am very happy with it and recommend it highly.
one last thing: for the swiss pass route, there are excellent sites with lots of details, which might make this book redundant.
