On the Southeast area of the district of Honolulu, Oahu, the Kuli‘ou‘ou Forest Reserve was first designated on February 13, 1914, by Governorʻs Proclamation, and currently consists of approximately 215 acres. It delivers a diverse opportunity for recreational activities. The switchbacks pass through a section reforested in 1934-35 by the Civilian Conservation Corps. CCC crews planted hundreds of Formosa koa and thousands of logwood trees along the slopes of Kuli`ou`ou Valley to reduce water runoff and thus erosion. The workers undoubtedly built a rudimentary trail network to access the planting areas, but volunteers and the staff of Na Ala Hele, the state trail program, constructed the current alignment in 1991-92.
