Zambales Mountains
From Wikipedia, the free encyclopedia.

The Zambales Mountains are on the western side of Luzon, in the Philippines. The mountains separate Luzon's central plain from the South China Sea and extend out as the Bataan Peninsula to the south, enclosing the Manila Bay.

Mt. Pinatubo is an active volcano in the mountain range and it erupted in 1991.
