Oahu known as "The Gathering Place", is the third largest of the Hawaiian Waikīkī is a neighborhood of Honolulu, in the City and County of Honolulu, on the south shore of the island of Oʻahu, in Hawaii. Waikiki Beach is the shoreline fronting Waikīkī.

Waikīkī is home to public places including Kapiʻolani Park, Fort de Russy Military Reservation, Kahanamoku Lagoon, Kūhiō Beach Park, and Ala Wai Harbor.

The neighborhood extends from the Ala Wai Canal (a channel dug to drain former wetlands) on the west and north, to Diamond Head (Lēʻahi) on the east. Waikīkī Beach is noted for its views of the Diamond Head tuff cone, its usually warm and cloud-free climate and its surf break.

The Waikīkī skyline is now dotted with an abundance of both high-rises and resort hotels. The beach is actually fairly short, with half of it marked off for surfers. For some distance into the ocean the water is quite shallow, although there are numerous rocks on the bottom. As with most ocean beaches the waves can have some force, particularly on windy days. The surf at Waikīkī is known for its long rolling break, making it ideal for long boarding, tandem surfing and beginners.
