If you want a splash in the ocean, take the resort's elevators or follow the outdoor steps from the main gate down a nine-flight high cliff to reach the white sands of Pu'u Poa Beach.  Fronting the Princeville Resort Kauai, amenities and... thoughtful hammocks are available for the hotel's guests at this scenic beach.  Don't be intimidated if you're not staying at the resort because thankfully in Hawaii, beaches are available for everyone to use as accorded by law.
