Subic Bay is a unique project on the site of a former United States Naval base. It was buried under ash after the eruption of Mt Pinatubo in 1991 and has since been transformed into a buzzing eco-tourism and commercial hub, only five minutes from Philippines International airport and a two-hour drive northwest of Manila. Most of the area, which is enclosed by a security fence, is covered in dense forests teeming with flora and fauna, including rare butterflies and bats. There are also lovely unspoiled beaches to enjoy, exceptional scenery, forest trails, watersport activities, coral reefs and shipwrecks to explore, numerous sports facilities and duty-free shopping centres.
