Keep it simple and do it right: Rather than sort through thousands of posts written by hundreds of people on sites like Yelp and TripAdvisor, pick up a Trailblazer guide. You will find the answers to all your questions.
Trailblazers are called the "Swiss Army Knife" of travel guides, since they are organized, comprehensive, and easy to use. The activities on each island are organized geographically, meaning things that are close by each other on the island are also close by in the book. Trailblazers also include Best Of sections that list the top choices for activities, a Trailblazer Kids section for families, and tips for saving money and staying safe.
Trailblazers are for independent, active people. You can pick what looks good and find a place to call your own.
All the top tourist attractions are listed in Trailblazer guides, but the books are also known for cultural and historic sites, as well as nonprofit centers.
When traveling to Kauai, Oahu, Maui, or the Big Island, pick up a Trailblazer before you go. These books take the guess work out of traveling to Hawaii.
