Waikiki Beach
The most famous beach in Hawaii and still one of the best for families. The water is calm and warm, the sandy bottom slopes gently, and beginner surf lessons are available all along the shore. Kids can build sand castles, take a catamaran cruise, or try stand-up paddleboarding. The beach is backed by hotels and shops so everything you need is within walking distance. Lifeguards are on duty and the Duke Kahanamoku statue makes a great photo spot. Yes it is touristy but kids do not care about that.
