Query: THE one to have along

We tested all the features of this book on our vacation last month. This book is definitely our first choice of all the Kauai guides. It proved itself a great alternative to all the package tours that can run up to over $100 per person for one outing. The authors provide easy driving directions, accurate trail descriptions, hike degree of difficulty, potential hazards.It was a big help knowing where to go the minute we hopped off the plane and was responsible for us having one fantastic time.
