Geography
Porac is 26 kilometres (16 mi) west from the provincial capital San Fernando, south of Angeles City and north of Floridablanca. A portion of Mount Pinatubo is in the municipality.
Porac has a hilly to mountainous terrain in the majority of its plains. Most rivers, if not all, are heavily silted by mudflow due to the eruption of Mount Pinatubo and succeeding lahar flows. Tourist spots include Darabulbul Falls (nicknamed Dara Falls) in Jalung, Miyamit Falls in Sapang Uwak, and the hot springs of Sitio Puning, accessed through Sapang Bato in Angeles. Babo Pangulo offers a view of Porac and Mount Negron.
