The Subic Bay Freeport Zone occupies the former US Naval Station Subic Bay — the largest American overseas naval base in the world until its closure in 1992. What was left behind was a large, well-maintained complex of roads, runways, warehouses, and facilities that the Philippine government converted into a duty-free economic zone. The result is an unusual destination: duty-free shops, adventure parks, and upmarket restaurants set inside a former military installation, with wide straight roads that feel unlike anywhere else in the Philippines.
For travellers, the Freeport is a base for activities rather than a destination in itself. Ocean Adventure and Zoobic Safari (a tiger theme park) are inside the zone, and the diving around the bay is good — the wrecks from wartime and the clear water attract divers from across Luzon. The Subic Bay International Airport handles some domestic flights, making it possible to fly directly into southern Zambales without going through Manila.
