Regional Details

Location and History
The origin of the name ‘Calib-ungan’ is believed to have come from two Tagalog words; ‘kalibong’ which means cauldron and ‘unga’ which translates to boiling stones. This refers to the steam that can be seen rising from its slopes when there are no clouds present. The locals also believe that it is home to deities who protect them from illness, famine, drought, and other disasters.

The climate in the area around Mount Calib-ungan is tropical with distinct wet and dry seasons that bring heavy rainfalls during the monsoon season. Summers are hot and humid while winters are mild with temperatures ranging from 18 degrees Celsius to 25 degrees Celsius. Winters bring about cool winds from the north which help to keep temperatures lower than other parts of the country. Due to its location on higher ground, Mount Calib-ungan can escape some of the worst effects from typhoons which often occur in other areas around the Philippines.

Heading north on Olongapo – Bugallon Road there is a bridge that crosses the Bucao River and leads to the Municipality of Botolan to the North, and the road then goes on to the larger and more established city of Iba.

Heading south on Bugallon Road after exiting Botolan, you will drive through the municipalities and cities of Cabangan, San Felipe, San Narciso, San Migues, San Antonio, Castillejos, Subic, Calpandyan, Olongapo, and the Subic Bay Freeport Zone.
