Like going to cities and avoiding rush hours or going to places without large crowds, such as small towns? Which do you mean?
Probably avoid Honolulu. Here’s some ‘hidden gems’ in Hawaii
Let’s tag @Hawaii_Jake into this
It isn’t that difficult. Go to Kauai, especially up by Hanalei,or down by Poipu. Go to Paia on Maui, and then out to Hana. Go north of Kapalua. Or go to Molokai. Just stay away from Honolulu or Kaanapali.
It’s quite simple. Stay off Oahu. Kauai is gorgeous. There’s lots to do. Maui has amazing beaches. The Big Island has some great stuff including a volcano that is quiet now. You can fly direct to all the islands and completely skip Oahu.
