Subic would be fun..... but if you prefer a more adventurous trip, there are a few travel/tour agencies that offer white water rafting (during this wet season) in Chico River, Cagayan.
I also suggest surfing, you can either go to San Juan, La Union in Western Luzon (South China Sea) or Baler, Aurora in Eastern Luzon ( Pacific Ocean), there are local surfing clinics there and even freelance surfing intructors.
Or go up to the mountains and revisit the Cordillera Rice Terraces- try the less popular ones - Mayoyao,Hapao and Kiangan.
If you are into festivals/fiestas, the nearest big one I know in Luzon is the Penafrancia Festival in Naga City ( Bicol Region) celebrated in honor of the Virgin every mid September. |
