Lonely Planet review
At the Diamond Head edge of Waikiki, Sans Souci is a prime sandy stretch of oceanfront that’s even further away from the frenzied tourist scene. It’s commonly called Kaimana Beach, as it’s next door to the New Otani Kaimana Beach Hotel. Local residents often come here for their daily swims. A shallow reef close to shore makes for calm, protected waters and provides good snorkeling. Strong swimmers and snorkelers can follow the Kapua Channel that cuts through the reef. Be aware that currents can pick up in the channel, so play it safe and check conditions with the lifeguards before heading out. Limited beach facilities include outdoor showers.
