Great book
The other reviews pretty much say it - best guide book I've read, well, to anywhere at all.

excellent
I just returned from the Big Island with a large group. We used this book extensively and there were no surprises - it was very accurate and enhanced our first trip to the Big Island, which is so beautiful. I wholeheartedly recommend this to anyone traveling to the Big Island!

great guidebook
I have nothing but good things to say about this series. The maps (so many of them!) are much easier to use than most others, because of the topographic shading. The trail maps are detailed, and mile markers on the road maps are a great help. The layout is very handy, with sights arranged in the order you would encounter them geographically. Lots of good photos, since so many places can't be adequately described with words.

Just Get It
If you are planning a trip to The Big Island you need to buy this book. We got 5 books from the library before purchasing this book, and this is the one we kept ging back to. Just get it.

This is simply the best guidebook available!
I compared it with three other guidebooks, and this one is hands down by far the best. I also like his sense of humor, and his ability to give us foreigners a realistic taste of the local culture. It is down to earth, not superficial, and it must have been a lot of work to write this guide! The first thing I did when I arrived in Oahu for the second segment of my trip was to go to the bookstore at the airport and buy his book for Oahu.
