I know we are biased but the best beach on Oahu bar none is Hukilau Beach. This is the beach nearest Laie on the North Shore of the island. It’s a small beach not heavily used and not a lot of tourists. It’s more for locals and BYU Hawaii students. In addition, it has nice sized waves for body surfing and boogie boarding. Our family are good swimmers, but we are not crazy surfers and enjoy this beach tremendously.
Last time we were there some new friends taught us the sport of chasing crabs. If you go to the beach at night with flash lights and buckets you can catch crabs, which the children love to do. These aren’t the large, let’s eat them kind, but we mainly caught the little ones that we then released.
We have run into the occasional “blue bubbles” on this beach. Blue bubbles are a small jelly fish but their sting is painful.
