Walk 10 minutes from the center of Waikiki towards Diamond Head and you’ll come across Kaimana Beach Park, also known as Sans Souci Beach. It’s a small, safe beach where children can play and anyone can swim without having to battle high surf. On weekends, it’s filled with local families barbecuing and playing volleyball, but during the weekdays—especially the early mornings—you might only share the beach or the water with just a few people. Adjacent to Kaimana is the Waikiki Natatorium War Memorial, which was dedicated to those who died in World War I. (Unfortunately, the Natatorium has been closed since 1979.)
To get there, walk along the promenade behind the Waikiki Aquarium. Once the path ends, just cross the grass and you’ll see the beach. But if you prefer to stick to the street-side sidewalk, go past the Aquarium for about five minutes. If you walk beyond the New Otani Hotel, you’ve gone too far—back up! The beach fronts the hotel.
