We are going to Hawaii in October and will have 6 days to explore. We have been to Maui and we thought this time we would go to Oahu's North Shore and Pearl Harbor and then add another island. We can't decide between going to the Big Island or Kauai.
We would appreciate any advice.
Thanks in advance.

With only 6 days, I would choose Kauai. It's easier to cover in that # of days than on the BI.

My two favorite islands. I agree w/ the other poster, Kauai would be best for a 6 day trip.

Big Island.

you won;t have enough time for the big island, so pick kauai, as everyone else has said.

Kauai
