Oahu is a mere 597 sq. miles, but families will find plenty of activities. Most of the action is in the south, around Waikiki; the north is very different, less developed, and well worth visiting.
11. Bishop Museum
Hawaii has an amazing history: ancient kings and queens (who surfed as part of the royal life), missionaries who "came to do good and did right well" (i.e. fathered families who grew rich and became a dominant elite), waves of immigrants brought in to work plantations... The Bishop Museum in Honolulu (which can be reached by bus) covers the gamut from Hawaiian rain gods to a planetarium show on the Space Station. Check web site for exhibit updates.12. Snorkeling at Hanauma Bay
The Hanauma Bay Nature Park is actually a State Underwater Park, and is known as a popular snorkeling spot.13. Climb Diamond Head
Diamond Head -- the landmark hill that overlooks Waikiki Beach -- is a State Monument, and a well-maintained trail leads up to the summit. The trail up is not difficult; round-trip is 1.4 miles. Recommended for those who like hiking, or want to see Waikiki spread out below; but if your family has limited time, you may want to concentrate on beach-and-sea activities in Waikiki.
14. Kualoa Ranch
This could be a good outing if you pick the right activities. (Guests sign up for several activities plus basic buffet lunch.) Many kids will enjoy horse-riding; Movie Set Tour (Jurassic Park, etc.) sounds promising. This place has a good base of great scenery and interesting history; but suss out current opinions before signing up.
