From Manila ride a bus to Infanta, Quezon. Get off at Famy and ride a tricycle to Kilometer 3 marker. From there its about 4 hours trek up Mt. Romelo (more if trail is muddy)
From the campsite on top of Buruwisan, you will be able to trek to 4 more waterfalls. Buruwisan is also a popular rappelling site. The water in Buruwisan's catch basin is emerald green and very cool. During the March - June the trail is not too muddy but the campsite is usually full. The rainy season (June - September) is best if you want to photograph the falls.
