Civilian Conservation Corps Camp in Kōkeʻe State Park
Civilian Conservation Corps Camp in Kōkeʻe State Park is located at Hawaii Route 550, in Waimea, on the island of Kauaʻi, in the U.S. state of Hawaii. It was built in 1935 with lumber that was put into the saltwater and floated to the shore at Port Allen, the seawater adding a natural termite protection to the lumber.
