The most American town in the Philippines, Olongapo City is located in the south of ZAMBALES PROVINCE . Subic Bay once a preferred rest and recreation port in the Pacific for the United States Seventh Fleet until the final withdrawal of the US navy in Nov, 1992 has developed into a special economic zone, with industry, shipyards and plenty of tourist facilities such as hotels, golf course, duty free stores and etc.

Barrio Barreto which is a two mile stretch along the beach and located twenty minutes from Olongapo City is filled with tourist facilities but Baloy which is five minutes from Barreto is a more preferred popular tourist place as rooms and foods here are cheaper than in Barreto. Journey up to the Zambales mountains visitors can find beautiful beaches in front of them. To further north of Olongapo City, the cleaner are the sand and water. The coastal road though very pity-holed, leads past many bay and offshore islands wonderful places for diving and on to Iba, the capital of Zambales.
