Great beer and food! Depending on where you are staying, this might be within walking distance. We came here a few times when we visited Hawaii!
Great spot for some beer, seltzer, and food! We love breweries, and this one has a huge bar and a place to sit outside near the tops of the palm trees.
If you're looking for something adventurous, we loved the UTV Raptor Tour (they filmed the stampede scenes from Jurassic Park here). There are also some other tours here, like e-bikes and ziplines! It is about an hour from Waikiki, but it is beautiful, and so is the drive!
Go here if you want to snorkel! We didn't think it was going to be that cool, but we both loved it and saw so many fish! The beach is also beautiful!
