Ever tried spelunking? Calinawan Cave in Tanay could be a nice option for a beginner! A little history: this cave used to be a rendezvous place for Filipino soldiers during the Japanese war. Touring around it takes only an hour or less. You can go visit the nearby Daranak and Batlag falls to maximize your itinerary. Take as much pictures as you want because the view is just breathtaking.
