Pocas playas han sido tan comentadas como la de Waikiki. Desde la década de 1950, esta playa es uno de los principales destinos turísticos. Al ver las playas de arena blanca y aguas cristalinas de un color azul profundo ya no se preguntarán por qué esta playa es tan popular. Si eso no es suficiente, este es además uno de los mejores sitios donde surfear en toda la isla. Por las noches, los visitantes se pasean con sus mejores prendas por la pasarela y los enamorados buscan recovecos apacibles bajo la protección de las palmeras. Con las mejores vistas de Diamond Head, la playa es el más puro reflejo del espíritu relajado de Hawái.

Escondida al fondo del frondoso valle de Manoa se encuentra la Cascada de Manoa, a la que muchos describen como uno de los paisajes más encantadores de O'ahu. Las aguas se dejan caer más de 30 metros por un precipicio antes de caer a la piscina natural a los pies, y su frescura contrasta de manera más que agradable con el aire caliente de Hawaii. La caminata hasta la cascada es de aproximadamente una hora de duración y no propone grandes dificultades. Cuando llueve, el sendero es bastante resbaladizo, pero cuando brilla el sol está bien delimitado y es fácil de recorrer.

Famoso por su bellísima playa de arena con forma de herradura y sus aguas calmas, transparentes y de color turquesa, este santuario natural marino es el hogar de miles de peces tropicales de todos los colores. En el arrecife, las aguas que llegan hasta la cintura son perfectas para aquellos que recién comienzan a practicar el snorkel. Los más experimentados sin dudas preferirán hablar con el guardavidas antes de aventurarse a aguas más profundas, donde podrán apreciar a las tortugas marinas y demás formas de vida acuática. La bahía está menos concurrida temprano por la mañana o a últimas horas de la tarde.

Located about a half-hour from Waikiki near the small country town of Waimanalo on the windward side of Oahu, this beach is simply gorgeous and crowd-free most of the time. The shoreline is wide, and the sand is soft and thick. This is one of the only beaches on the island that can be closed for military training, and there is also a portion of the beach designated for those with military IDs. Surf break is consistent and fun for all levels, but kids should be supervised at all times since rogue waves can appear suddenly. No surfing is allowed between the two lifeguard towers. This lifeguarded beach comes along with free parking, picnic tables, restrooms and showers.

Windsurfers, a breed apart from regular humans and similar to wave surfers, travel from far-distant corners of the world to hit this top windsurfing beach. When the water is flat, they simply sit and wait. When the wind starts, they head here in droves. If you are not a windsurfer, you can still enjoy the warm waters and gentle surf of this famous, beautiful beach. Barbecue facilities, bathrooms, and showers are available.

This is reputed to be one of Oahu's most beautiful beaches, and that is high praise indeed. The aquamarine waters, smooth white sands, and gently swaying palm trees epitomize South Pacific paradise. Of course, when the wind is up, the hordes of energetic windsurfers quickly dissolve any fantasies of being marooned on a tropical island. Still, most of the time, Lanikai Beach is fairly quiet, and even when it's not, one must gape a bit at its natural beauty of it. Note: As with all Hawai'i beaches, conditions are changeable. Check with the lifeguards or locals before entering the water, and always use caution.

Dolphin and sea lion shows, a Hawaiian monk seal center, a sea turtle lagoon and a seabird sanctuary are a few of the highlights at this 62-acre ocean theme park on the coast of East O'ahu.
