Nuʻuanu Pali Tunnels

Nuʻuanu Pali is a section of the windward cliff (pali in Hawaiian) of the Koʻolau mountain located at the head of Nuʻuanu Valley on the island of Oʻahu. It has a panoramic view of the windward (northeast) coast of Oʻahu. The Pali Highway (Hawaii State Highway 61) connecting Kailua/Kāneʻohe with downtown Honolulu runs through the Nuʻuanu Pali Tunnels bored into the cliffside. The area is also the location of the Nuʻuanu Freshwater Fish Refuge and the Nuʻuanu Reservoir in the jurisdiction of the Hawaiʻi Department of Land and Natural Resources. The Nuʻuanu Pali State Wayside is a lookout above the tunnels where there is a panoramic view of Oʻahu's windward side with views of Kāneʻohe, Kāneʻohe Bay, and Kailua. It is also well known for strong trade winds that blow through the pass (now bypassed by the Nuʻuanu Pali Tunnels). The Nuʻuanu Pali Tunnels were built in 1958. Before this road opened, people would use what is now known as the Old Pali Road, currently a popular hiking route.

Pu'u Kōnāhuanui consists of two mountain peaks located in Honolulu County, Hawaii. It is the highest point in the Koʻolau Mountains and second highest point on the island of Oahu.The Hawaiian word "Kōnāhuanui" roughly translates to "large testicles" in English. This alludes to a legend that states the mountain originated from the testicles of a giant, who threw them at a woman trying to escape from him.

Saint Stephen Seminary was a diocesan minor seminary staffed by the Sulpician Fathers in the diocese of Honolulu that closed in 1970. The seminary land was founded in 1946 when the Diocese of Honolulu obtained the 22 acre (89,000 m2) estate of Harold K.L. Castle, which was built in 1927. It is located above Maunawili valley in the Koolaupoko district of the island of Oahu. It currently serves as the residence of the bishop of Honolulu. At its peak the seminary accommodated some 70 high school and college students from Guam, other Pacific Islands and the State of Hawaii. The seminary flourished in the 1950s and '60s, but dwindled and closed in the early 1980s. After the seminary's closure, the Cullinan Building was transformed into a diocesan center housing various officers of the diocesan curia. Since the episcopate of Msgr. John Scanlan, the seminary grounds have also housed a Carmelite monastery of discalced nuns from Hong Kong. Currently, candidates for priestly formation in the Diocese of Honolulu attend the metropolitan seminaries of Saint Joseph in Mountain View, California, and Saint Patrick in Menlo Park, California.

The Kaneohe Ranch Building at Castle Junction, where the Pali Highway (Route 61), Kamehameha Highway (Route 83), and Kalanianaʻole Highway (Route 72) intersect on the windward side of Oʻahu, was built in 1940 to be the headquarters of Kaneohe Ranch, which owned 12,000 acres (49 km2) of surrounding land and played a major role in the history of Kāneʻohe and Kailua. The building is significant both for its association with the Ranch and for its Hawaiian style architecture designed by Albert Ely Ives (1898-1966). Ives' other work on the windward side includes Plantation Estate which is the Winter White House of Barack Obama. The building was added to the National Register of Historic Places on 5 June 1987.The building exhibits key features of the style of Hawaiian architecture that developed during the 1920s and 1930s: the double-pitched Dickey roof with overhanging eaves, plaster-covered masonry walls, and ample cross-ventilation. Its architect was best known for his residential work; this is one of his few commercial buildings.During the mid-19th century, most of the land in the area belonged to Kalama, Queen Consort of Kamehameha III and later Queen Dowager of the Kingdom of Hawaiʻi. She and Judge Charles Coffin Harris began a sugarcane plantation on the land, but after she died in 1870 and it failed in 1871, the land eventually passed to Harris's daughter, Nannie H. Rice, who in 1893 leased 15,000 acres (61 km2) to J. P. Mendonca, who founded Kaneohe Ranch in 1894. Lower-lying wetlands were leased to Chinese rice farmers. In 1907 James Bicknell Castle became the principal stockholder of the Ranch, and 1917 his son, Harold K.L. Castle, purchased the land from Mrs. Rice. Most of the land was used for cattle-ranching until World War II, when the military took over much of it. After the war, former ranch lands have provided room for ever expanding residential subdivisions.

Hawaiʻi Loa College was a private, four-year, liberal arts college in Kaneohe, Hawaii, founded in 1963 as Christian College of the Pacific by a consortium of four Protestant church denominations in Hawaii, with land deeded by Harold K.L. Castle on which to build a campus. The idea originated with Rev. Harry S. Komuro, then superintendent of the Methodist Mission in Hawaii, and the founding trustees were Dr. Joseph Bevilacqua, general secretary of the United Church of Christ; Rev. Frank E. Butterworth, pastor of First United Methodist Church of Honolulu; Bishop Harry S. Kennedy of the Episcopal Diocese of Hawaii; and Dr. William E. Phifer, Jr., pastor of First Presbyterian Church of Honolulu. Other early trustees included Herbert Choy, Frank Damon, Jr., Dr. Wesley Hotchkiss, Ernest K. Kai, and Ted Tsukiyama.In September 1964, the name was changed to Hawaii Loa College (HLC), a new logo was chosen, and a new motto was adopted: ʻAʻole i kaupoʻo i kaupoʻo ana no ("My height is not yet reached"). A master planning committee was also formed and an architect hired to plan the new campus on 150 acres (0.61 km2) of scenic former Kaneʻohe Ranch land on the Windward side of Oʻahu, looking up at the Koʻolau Range directly beneath the Pali Lookout. The committee chair was Bruce McCandless and the architect was William L. Pereira & Associates.In May 1965, the trustees hired the college's first president, Chandler W. Rowe, former dean of academic affairs at Lawrence University, who began assembling a faculty and administrative staff in order to be able to accept the first students in the fall 1967. Until the Windward campus opened in the fall of 1971, the school borrowed facilities on the campus of Chaminade University of Honolulu (1967–68), then at 2345 Nuʻuanu Avenue (1969–70) nearer downtown Honolulu. By 1970, the senior class numbered 27 students.Later presidents include HLC philosophy professor Philip J. Bossert (1978–86) and University of Denver chancellor emeritus Dwight M. Smith (1990–92).The beautiful rural campus site was both a blessing and a curse. Lack of infrastructure made it very difficult to expand campus facilities to serve more students and raise more revenue, making operations a constant financial struggle. By 1992, Money magazine ranked HLC number 13 in the west among America's best college buys. However, in that same year, faced with loss of accreditation and saddled with $3 million in debt, Hawaiʻi Loa College merged with Hawaiʻi Pacific University.

The John H. Wilson Tunnels are a pair of highway tunnels passing through the Ko‘olau Range on the island of O‘ahu. The tunnels are located on Likelike Highway (Route 63), which connects Kāneʻohe with Honolulu, and are 2775 feet (845.8 m) long westbound and 2813 feet (857.4 m) long eastbound, at 21°22′39″N 157°48′54″W. The tunnels are named after former Honolulu Mayor John H. Wilson, who built the first carriage road over the Nu‘uanu Pali in 1898. While mayor, Wilson advocated a tunnel connecting Kaneohe with Honolulu through Kalihi Valley. The City and County of Honolulu spent US$12 million on the tunnels and highway. Construction started on the Honolulu-bound tunnel in January 1954, and the Kāneʻohe-bound tunnel in 1957. Five people died during their construction, and they were opened to traffic in November 1960. The tunnels are now maintained by the Hawaii State Department of Transportation.

Mānoa Falls is a 150-foot (46 m) waterfall along the Manoa Falls Trail in Honolulu, Hawaii. Swimming in the pool below the waterfall is highly discouraged because there is a threat of becoming infected with Leptospirosis, a disease causing mild to moderate flulike symptoms that can last for 1 to 2 weeks. Many tourists are attracted to the waterfall and the scenery throughout the trail leading to it. Another attraction near Mānoa Falls is the Lyon Arboretum, which preserves many endangered Hawaiian plant species. The hike to the waterfall and back takes about one hour. The waterfall and surrounding area experience rainfall almost every day, and flash floods can occur.

The Hoʻomaluhia Botanical Garden (approximately 400 acres) is a botanical garden located at 45–680 Luluku Road, Kāne'ohe, Oahu, Hawaii. It is part of the Honolulu Botanical Gardens, and is open daily, without charge, except for Christmas Day and New Year's Day. The garden was established in 1982, and designed and built by the United States Army Corps of Engineers for flood protection. It is a rainforest garden, with plantings from major tropical regions around the world, grouped into distinct collections that focus on Africa, Hawaii, India and Sri Lanka, Malaysia, Melanesia, the Philippines, Polynesia, and the tropical New World. Special emphasis is placed on conserving plants native to Hawaii and Polynesia, as well as arecaceae, aroids, and heliconias. The garden includes a lake (32 acres) and walking trails, as well as a day use area, campgrounds, and a visitor center with lecture room, exhibition hall, workshop, and botanical library.

Kaniakapūpū ("the singing of the land shells"), known formerly as Luakaha ("place of relaxation"), is the ruins of the former summer palace of King Kamehameha III and Queen Kalama on the island of Oahu in Hawaii. Built in the 1840s, and situated in the cool uplands of the Nuʻuanu Valley, it served as the king and queen's summer retreat after the capital of the Kingdom of Hawaii moved from Lahaina to Honolulu in 1845. It was famous for being the site of a grand luau attended by an estimated ten thousand guests during the 1847 Hawaiian Sovereignty Restoration Day celebration. The palace had fallen into ruins by 1874; no records exist about its condition in the intervening years. Rediscovered in the 1950s, the site was cleared and efforts were made to stabilize the ruins from further damage by the elements and invasive plant growth. The site remains officially off-limits to the public and trespassers are subjected to citations, although the site is not regularly monitored.

Hoʻokuaʻāina is a nonprofit organization that maintains approximately 3 acres of loʻi kalo in Maunawili, Hawaii. Founded by Dean and Michele Wilhelm, who purchased the nonprofit's 7.6-acre site in 2007 for the purpose of growing kalo. Hoʻokuaʻāina cultivates several varieties, selling them raw, cooked, and as poi. The nonprofit steams and cleans more than 400 pounds of kalo per month.Hoʻokuaʻāina runs programs focused on mentorship for at-risk youth and hosts community workdays at the loʻi, offering internships.

The Harold L. Lyon Arboretum is a 200-acre (0.8 km2) arboretum and botanical garden managed by the University of Hawaiʻi at Mānoa located at the upper end of Mānoa Valley in Hawaiʻi. Much of the Arboretum's botanical collection consists of an artificial lowland tropical rainforest with numerous trails and small water features.

Maunawili (Hawaiian pronunciation: [mɐwnəˈvili]) is a residential census-designated place (CDP) in the City & County of Honolulu, Koʻolaupoko District, Island of Oʻahu, Hawaii, United States. As of the 2020 census, the CDP had a population of 2,026. Situated mauka (inland or mountain side) of Kalanianaʻole Highway between Castle Junction and Castle Hospital, Maunawili is nearly all private homes, schools, and a few churches; horse stables complete the rural setting. There are no commercial establishments. However, residents are only minutes (by car or bus) from Kailua. Maunawili Valley extends behind the prominent windward peak known as Olomana. The residential developments extend only part way back into the valley, which is quite large and fairly wet, supporting limited agriculture (mostly banana growing) behind the housing. Water from the numerous streams is diverted by a ditch to much drier Waimānalo to support agricultural activities there. A golf course and agricultural research station (HSPA) are located in the valley. The agriculture research station is also home to a sugar cane, coffee and cacao breeding program. An attraction of increasing popularity is the Maunawili Demonstration Trail, a state-maintained trail that traverses the breadth of upper Maunawili Valley from the Pali Highway (access at the "Horseshoe Curve") to Waimānalo. A connecting side trail (Maunawili Falls Trail) is accessible from the neighborhood in upper Maunawili. The U.S. postal code for Maunawili is the same as for Kailua: 96734.
