John Hay Air Base, more commonly known as Camp John Hay, was a major hill station located near Baguio City used for rest and recreation for personnel and dependents of the United States Armed Forces in the Philippines as well as Department of Defense employees and their dependents. It was last run by the United States Air Force. While officially designated a communications station, the facility was mainly used for rest and recreation. The facility housed The American Residence as well as Broadcasting facilities of the Voice of America.
Just before the facility was turned over to the Philippines, it had 290 fully-furnished rooms in the different cottages, duplexes, apartments, and lodges, which are scattered about the complex. Some of these billeting units were equipped with color television sets, refrigerators, and cooking facilities.
The base's popular spots are the 19th Tee, Halfway House, Scout Hill baseball field, Main Club (also known as Officer's Building), and the well-known Mile-Hi Recreation Center. It was off-limits to the general public, except for some who had access due to connections or official business.
