2 to 3 hours depending on how good you are overtaking tricycles in the middle of a 2 lane road ehehehehe! dami tricycles sa olongapo-gapan road. then add another 30 minutes to ocean adventure. watch out for monkeys on the road, if you leave at 7am then by the time you reach subic that will be just about the time they come out to the road side. meron kami nakita last time we were there na monkey, nasagasaan yung tail nya tapos hindi naputol. meron na gangrene yung tail, kawawa.
