Going to Oahu for the 1st time for 12 days in September to dog sit for an old co-worker who moved there a couple of years ago and is coming home for a visit. She lives in Waipahu and has also generously offered the use of her car during our stay so we will be mobile. I am sure she will have plenty of tips and suggestions for us but thought I'd ask for additional imput on can't miss places or things on the leeward side that she may not know about yet since she hasnt really lived there long and that is where we will be based. Finding plenty of info on the more known tourist destinations on other areas of the island which we plan to take in on several different days but not much on her side of the island. We like quirky, odd and interesting things in addition to historical and beautiful places. We are fairly fit but not athletic and not into the party scene but are open to all suggestions. I know this isnt the popular side of the island but I also am sure there must be plenty to do in the area even tho not talked about much on travel sites. I have found so many tips from posters here on Trip Advisor that I wouldnt have found anywhere else and thank all in advance for any replies!
