East Honolulu, Hawaii

Maunalua Bay is a bay in the southeast of Honolulu, the capital of Hawaiʻi. The bay extends about 6.3 miles (10.1 kilometers) from the southern tip of Diamond Head, the Black Point, also called Kūpikipikiʻō , in the west to Portlock Point, also known as Kawaihoa Point, to the east. On the land side, just to the east of Diamond Head is the upmarket suburb of Kāhala. Following are several affluent hillside suburbs like Hawaii Loa Ridge, a gated community that occupies an entire slope. In the east is the suburb of Hawaii Kai, built by industrialist Henry J. Kaiser after World War II. Hawaii Kai has a marina, shopping centers, including a Costco, Walgreens, Longs, and Safeway, and numerous restaurants such as the well-known Roy's and Kona Brewing Co. pub. On the headland leading to Koko Head is the suburb of Portlock, which is a part of Hawaii Kai. The name Maunalua (from Mauna = mountain and [ʻe]lua = two, in the native Hawaiian language) refers to the designation of the area what is now referred to as "Hawaii Kai." The mountains, located inland from Portlock Point, are the 645 feet (197 meters) high Koko Head, and about 2.2 miles (3.5 kilometers) east thereof, close to Hanauma Bay the Koko Crater, the walls of which rise up to 1,207 feet (368 meters). According to one legend, Maunalua was one of the first settlements when settlers arrived in Hawaiʻi around the 12th century. Native Hawaiians originally lived there by fishing and cultivating sweet potatoes (ʻuala) along the coastal plains at a place called Ke-kula-O Kamauwai. Maunalua was formerly famous for having the largest Native Hawaiian fishpond (loko iʻa) on Oʻahu. The 523 acre fishpond known as Keahupua-O-Maunalua had a wall or kuapā which originally spanned from Kuliʻouʻou headland and to what is now Portlock. The pond was used primarily to raise mullet (ʻanae) and was also home to a multitude of endemic or indigenous waterbirds. The area continued to be important for fishing and agriculture until the 1950s when the fishpond was filled for housing development.

Hawaiʻi Kai, also known as Maunalua or Koko Marina, is a largely residential area located in the City & County of Honolulu, in the East Honolulu CDP, on the island of Oʻahu. Hawaiʻi Kai is the largest of several communities at the eastern end of the island. The area was largely developed by Henry J. Kaiser around the ancient Maunalua fishpond and wetlands area known as Kuapā (meaning "fishpond wall"). Hawaiʻi Kai or Koko Marina was dredged from Kuapā Pond starting around 1959. Dredging not only transformed the shallow coastal inlet and wetlands into a marine embayment, but was accompanied by considerable filling and clearing of the pond margins. In 1961, Kaiser-Aetna entered into a lease agreement with the land owner, the Bernice Pauahi Bishop Estate, to develop the 521 acre (2.11 km2) fishpond into residential tracts with a marina and channels separated by fingers of land and islands upon which house lots and commercial properties would be laid out and developed. Nearly all of the low-lying lands surrounding the marina have since been developed, and neighborhoods now extend back into the several valleys and up the separating ridges.

Hanauma (; Hawaiian: [həˈnɔumə]) is a marine embayment formed within a tuff ring and located along the southeast coast of the Island of Oʻahu in the Hawaii Kai neighborhood of East Honolulu, in the Hawaiian Islands.Hanauma is one of the most popular tourist destinations on the Island and has suffered somewhat from overtourism. At one time, this popular tourist destination accommodated over three million visitors per year. In 1956, dynamite was used to clear portions of the reef to make room for telephone cables linking Hawaii to the west coast of the US.

Koko Head is the headland that defines the eastern side of Maunalua Bay along the southeastern side of the Island of Oahu in Hawaii. On its western slope is the community of Portlock, a part of Hawaiʻi Kai. Koko Head (at 642 ft or 196 m) is an ancient tuff cone that is somewhat dwarfed by its neighboring tuff cone, Koko Crater, with its peak, Kohelepelepe (or Puʻu Mai), rising to 1208 ft or 368 m. Koko Head itself has three significant depressions or old vents, the largest of which forms the well-known Hanauma Bay. Koko Head's last eruption was 3,000-5,000 years ago and it is part of the Honolulu Volcanics.This eastern end of Oʻahu is quite scenic and most of the area is part of Koko Head Regional Park, administered by the City & County of Honolulu. The following features and natural areas are found between Koko Head and the eastern end of the island at Makapuʻu: Koko Crater is a large tuff cone that visually dominates the area. Within the crater are horse stables and the Koko Crater Botanical Garden specializing in cacti and succulents. Hanauma Bay is a tuff ring breached by the ocean. Lānaʻi Lookout is a scenic lookout that features a very distant view of the Island of Lānaʻi to the southeast of Oʻahu. Molokaʻi, directly across the Ka'iwi Channel, is closer and nearly always visible during the day; Lānaʻi is visible only under good atmospheric conditions, although if visible from anywhere on Oʻahu, it will be visible from this pull-out/parking area. The cremated ashes of Barack Obama's mother and maternal grandmother were scattered here in 1995 and 2008. Hālona Blowhole is a blowhole in the rocky shore. A large pull-out/parking area is present. The adjacent Hālona Cove is best known as the site of the love scene between Burt Lancaster and Deborah Kerr in the movie From Here to Eternity. Sandy Beach is a popular beach for surfing and a park popular for kite flying because trade winds (offshore here) are strong and steady most days. Sea conditions off the beach tend to be rough most of the time and the bottom drops away relatively quickly, so this is not a beach for relaxed swimming, but very popular for more extreme water sports and watchers.

The Koko Crater Botanical Garden (60 acres) is a botanical garden located within the Koko Crater (Koko Head) on the eastern end of Oahu, Hawaii. It was given the dual title of the Charles M. Wills Cactus Garden by the Honolulu Department of Parks and Recreation, in recognition of his contributions to the garden, in 1966. The garden is part of the Honolulu Botanical Gardens, and first established in 1958. Its hot, dry climate is suitable for Plumeria and Bougainvillea cultivars in the outer crater, kiawe (Prosopis pallida) and koa haole (Leucaena leucocephala) trees, and four major collections organized by region (Africa, the Americas, Hawaii, and Pacifica). Other collections include adeniums, alluaudias, aloes, baobabs, cacti, euphorbias, palms, and sansevierias, as well as a native grove of wiliwili trees (Erythrina sandwicensis). A loop trail (2 miles) runs through the collections. They have about 500 trees and 200 species of trees.

Hālona Blowhole is a rock formation and a blowhole on the island of Oahu, Hawaii off of Hanauma Bay at Hālona Point overlooking the Pacific Ocean. In Hawaiian hālona means "lookout".
