Anyone traveling to The Big Island would enjoy what I think is the best guide book ever written about The Big Island. The book is called "The Big Island Revealed" by
Andrew Doughty. It leads you to all the great visitor attractions, such as Volcano National Park, beaches, snorkeling/diving, golf courses, restaurants, shopping and much much more. Whenever we're there we keep the book handy. When not we refer to it to reminisce. It can be found at Barns & Noble, Borders, Amazon and other book stores.
