Koʻolau Range

Oʻahu Forest National Wildlife Refuge was established in 2000 to protect fish, wildlife, and plants which are listed as threatened or endangered species. The refuge encompasses approximately 4,525 acres (18.31 km2) and is managed by the U.S. Fish & Wildlife Service.

Keaīwa Heiau State Recreation Area is the ruins of a temple (Heiau in the Hawaiian language) at the summit of a hill and neighborhood called ʻAiea Heights on Oʻahu, Hawaiʻi. The recreation area includes camping facilities and a 4.8-mile (7.7 km) trail. It also offers clear views of Pearl Harbor. The high point of Puu Uau is about halfway down the trail, where native ohia lehua and koa trees may be viewed. The remains of a military plane that crashed in 1944 can also be seen along the trail. The hike is not particularly difficult, however it does include one quite steep switchback stretch and can be extremely muddy if it has just rained. Allow for around 2.5 hours of easy strolling. A possible translation of Keaʻiwa would be mysterious, incomprehensible. It is believed that this name was given in reference to the healing powers of the plants that no one could really explain. In addition, Keaiwa Heiau may have also been known as a "Heiau Hoʻola," or the healing or life-giving heiau according to native Hawaiian scholar Mary Kawena Pukui.Foresters replanted most of this area in the late 1920s. The lemon eucalyptus trees give forth a mild citrus scent in the air. The trail's lower end is marked by stands of Norfolk Island pine trees. Pu'u Uau, the trail's high point around halfway along the length, is surrounded by native koa and ohi'a trees. There is also wreckage of a B-24 aircraft that went down in 1944. The name "Keʻaiwa" means "strange" or "incomprehensible" in Hawaiian. Perhaps the name refers to the idea that the powers of the kahuna and the plants employed in healing are unfathomable.Erected sometime in the 16th century by Kakuhihewa, the 15th Aliʻi ʻAimoku, or ruling chief, of Oahu, the 100 feet (24 m) by 160 feet (49 m) stone temple had walls averaging 4 ft in height and 5 ft in width. The walls consisted of numerous evenly faced one foot stones that are filled with rubble. Abundant medicinal herbs in the area were used by kahuna as a type of ancient herbal clinic. The kahuna would also train haumana (students) interested in the art of laʻau lapaʻau (healing medicine). The kahuna would also train students in the practice of praying, fasting, and medicinal healing using the neighboring plants. The reputed healing powers of the surrounding plants still draws visitors who leave temple offerings, hoping to experience medicinal benefits.Most of the trees in the area were replanted during the early 20th century. Although native species can be found at the highpoint of the trail. The remnants of a military airplane that crashed onto the area in 1993 can also be seen from the trail.The site provides a map for the 4.5 miles (7.2 km) Aiea Loop Trail. Several varieties of trees and other vegetation are enjoyed by visitors who make the trek.

Kahaluʻu (; Hawaiian pronunciation: [ˈkɐhɐˈluʔu]) is a residential community and census-designated place (CDP) in the City and County of Honolulu, Hawaii, United States, in the District of Koolaupoko on the island of Oahu. In Hawaiian ka haluʻu means "diving place". As of the 2020 census, the CDP had a total population of 5,241.

Ahuimanu or ʻĀhuimanu (Hawaiian pronunciation: [ʔaːhuwiˈmɐnu]) is a census-designated place (CDP) in the City & County of Honolulu, Hawaii, United States, on the island of Oahu. In Hawaiian ʻāhui-manu means "cluster of birds". Ahuimanu is spread out beneath the steep windward pali (cliff face) of the Koolau mountain and separated by a low ridge from Heeia Kea. Thus, this area is mostly inland and not directly on Kaneohe Bay. However, one neighborhood spreads over the ridge and along Kamehameha Highway where there is private access to the bay shore. Proximity to the pali gives the place a generally wet climate. As of the 2010 Census, this largely residential area had a population of 8,810. A small commercial mall is located here across the highway from the Valley of the Temples Memorial Park, a large cemetery noted for its Byodo-In Temple. The U.S. postal code for Ahuimanu is 96744.

The Kahaluʻu Taro Loʻi Historic District, also known as the ʻĀhuimanu Taro Complex, in Kahaluʻu on the windward side of Oʻahu, is the most complex and largest intact system of terraces for growing wetland taro on Oʻahu. It contains at least 18 loʻi (pondfield) terraces once watered by ʻĀhuimanu Stream and associated ʻauwai (irrigation ditches) over about 25 acres (100,000 m2) that start from headwaters just below the cliffs of the Koʻolau Range. It was added to the National Register of Historic Places in 1973, after windward residents raised concerns about development plans in the area. The Kahaluu Fish Pond was also added to the National Register at that time. The terraces are roughly rectangular in shape and average 5 by 10 meters in size, with front facings of stacked stone ranging up to 2 meters or more in height. The pondfields have all been silted in and are often obscured by heavy overgrowth of hau, mango, and guava trees, but they have withstood many generations of heavy rainfall on steeply sloping hillsides, in silent testimony to ancient Hawaiian expertise in irrigation and flood control. In 1973, a University of Hawaiʻi archaeology program field school excavated soil profiles from the terraces, and the site was cleared during the 1980s, but the State of Hawaiʻi Historic Preservation Division is now seeking community organizations willing to clear the site and make it operational again.The site is owned by Temple Valley Corp., which has continued to develop new houses around it. At the time of the NRHP nomination, the Historic District was said to lie 900 meters west of the west end of Hui Kelu Street and to be accessible via an abandoned jeep road. Even as late as July 1996, a hiker described returning via the jeep road. But Hui Kelu Street has since been extended across ʻĀhuimanu Stream, where the hiking trail begins, and the lower portion of the jeep road is now Heno Place.

Kahaluʻu Fishpond, historically known as Kahouna Fishpond, on Kāneʻohe Bay in windward Oʻahu, is one of only four surviving ancient Hawaiian fishponds on Oʻahu that were still in use well into the 20th century. In the previous century there were at least 100 such fishponds around the island. Kahouna was in use until about 1960 and was added to the National Register of Historic Places in 1973, after members of the surrounding community raised concerns that it would be destroyed by development. The Kahaluu Taro Lo'i Historic District was also added to the National Register at that time. Kahouna features a semicircular seawall about 1,200 feet (370 m) long. The inner and outer faces of the original wall were of stacked stone, with gravel, coral rubble, and soil as fillers between them.Like its larger counterparts at Moliʻi and Heʻeia, Kahouna Fishpond is now private property. Of the four major fishponds on Oʻahu, only Huilua Fishpond is open to the public. Kahaluu Pond, Inc., now leases its property for Hawaiian weddings. There is a wedding chapel at one end and a pavilion and garden area at the other, each leased to different vendors. Columbia Pictures also filmed part of The Karate Kid Part II, at the site.

Pearl City High School is located in Pearl City, in the City and County of Honolulu in the state of Hawaii, USA. Established in 1971, Pearl City High School is a public, secondary, co-educational, college preparatory high school that is part of the Hawai'i Department of Education, governed by the Board of Education. During the school's first year of operation, only buildings A and B existed. The school has since expanded, with the C to F, K, L and M buildings. Most buildings have three or four floors, making Building F the only single floor building, with two rooms for its natural resources class and weightlifting room. The sculptures Moon Beyond the Fence by Satoru Abe and Kua Kua Lua by Donald M. Page are on the campus.Pearl City High School earned the maximum accreditation term of six years in 2006 by the Western Association of Schools and Colleges.

Camp H. M. Smith is a United States Marine Corps installation in the Halawa census-designated place on the island of Oahu, Hawaii, near the community of Halawa (ha-LA-va) Heights. It is the headquarters of the United States Indo-Pacific Command (INDOPACOM), Special Operations Command Pacific, and Marine Forces Pacific, the Marine service component command of INDOPACOM. The camp, originally the Aiea Naval Hospital, was named for General Holland McTyeire Smith, the first commanding general of Fleet Marine Force Pacific, on June 8, 1955. The initials H. M. also stood for his nickname which was "Howling Mad" referring to his temper and given to him by his Marines.

Waikāne or Waikane (Hawaiian pronunciation: [vɐjˈkaːne]), also known as North Koʻolaupoko ([-koʔolɐwˈpoko]), is an area and census-designated place in the County of Honolulu, Hawaii, United States, on the island of Oʻahu. It had a population of 778 at the 2010 census. In Hawaiian, koʻolau poko means "short windward", referring to the fact that this is the shorter of the two windward districts on the island (Koʻolauloa or "long windward" is the other). Koʻolaupoko extends from Makapuʻu Point on the southeast to Kaʻōʻio Point on the north. Included within the district, south of North Koʻolaupoko, are the largest windward towns of Kāneʻohe, Kailua, and Waimānalo. Waikāne lies mostly along the coastline of Kāneʻohe Bay and consists of several lush valleys that extend inland to the steep face of the Koʻolau pali (cliff). The first valley north of Kahaluʻu is Waiāhole. Next is Waikāne, then Hakipuʻu, and northernmost is Kualoa. This area differs from the towns, valleys, and ahupuaʻa of the southern part of Koʻolaupoko in that it is mostly undeveloped, decidedly rural in character, with many small farms. Despite the long shoreline, public access to Kāneʻohe Bay is somewhat limited by private holdings. A small community park at Waiāhole was enlarged and improved in 2003. A larger city and county park at Kualoa provides camping and picnic areas, a long narrow beach, and views of Mokoliʻi Islet. The south side of Kualoa Regional Park faces onto Kāneʻohe Bay, and the east shore is a fringing reef off the Pacific Ocean coast of northeast Oʻahu. The U.S. postal code for all of North Koʻolaupoko is 96744 (the same as Kāneʻohe).

Honolulu County (officially known as the City and County of Honolulu, formerly Oahu County) is a consolidated city–county in the U.S. state of Hawaii. The city–county includes both the city of Honolulu (the state's capital and largest city) and the rest of the island of Oʻahu, as well as several minor outlying islands, including all of the Northwestern Hawaiian Islands (islands beyond Niihau) except Midway Atoll.The consolidated city-county was established in the city charter adopted in 1907 and accepted by the Legislature of the Territory of Hawaii. As a municipal corporation and jurisdiction it manages aspects of government traditionally exercised by both municipalities and counties in the rest of the United States. As of the 2020 United States Census, the population was 1,016,508. Because of Hawaii's municipal structure, the United States Census Bureau divides Honolulu County into several census-designated places for statistical purposes. The mayor of Honolulu County is Rick Blangiardi. The county motto is "Haʻaheo No ʻO Honolulu (Honolulu Pride)". About 70% of the state's population lives in Honolulu County. Only Nevada has a higher percentage of its population living in its most populous county. 43.0% of residents identify as Asian or Asian American, the highest of any US county.

Waimalu (Hawaiian pronunciation: [vɐjˈmɐlu]) is a census-designated place (CDP) in Honolulu County, Hawaiʻi, United States. The population was 13,817 at the 2020 census.

The Byodo-In Temple (Japanese: 平等院テンプル, Byōdōin Tenpuru) is a non-denominational Buddhist temple located on the island of Oʻahu in Hawaiʻi in Valley of the Temples Memorial Park. It was dedicated in August 1968 to commemorate the 100th anniversary of the first Japanese immigrants to Hawaiʻi.The temple is a replica of a 900-year-old Buddhist temple at Uji in Kyoto Prefecture of Japan. Contrary to popular belief, it is not a functioning Buddhist temple in the proper sense as it does not host a resident monastic community nor an active congregation. Inside the Byodo-In Temple is a 18 ft (5.5 m) statue of the Lotus Buddha, a wooden image depicting Amitābha. It is covered in gold and lacquer. Outside is a three-ton, brass peace bell. Surrounding the temple are large koi ponds that cover a total of 2 acres (0.81 ha). Around those ponds are lush Japanese gardens set against a backdrop of towering cliffs of the Koʻolau Range. The gardens are home to sparrows and peafowl. The temple covers 11,000 sq ft (1,000 m2).The Byodo-In Temple is visited and used by thousands of worshipers from around the world. It welcomes people of all faiths to participate in its traditions. Apart from worship, the temple grounds are also used for weddings and office meetings.
