Kaimana Beach

"Carefree Snorkeling at Sans Souci Some of the best snorkeling we did on Oahu didn't cost a cent—including Sans Souci Beach, a walkable distance from the Waikiki hotels and close to the aquarium. But why pay to get into the aquarium when you can wade right into the water and see all kinds of colorful needlefish, triggerfish, butterflyfish, and more? This smallish, family-friendly beach is low-key and fairly quiet, considering its touristy location. Swim over by the rock wall for the greatest variety of fish and tiny black crabs. And don't forget your underwater camera! (This is not a great picture, but at least you can see the aquatic diversity on display.)"
