Take the road south from Aborlan until you see a sign on the right pointing( 15kms or so) the way to Estrella, then follow the dusty road for around 10 kms then you will reach the falls. You must sign the book and pay a small entrance fee. There are shelters, picnic tables and a swing on a tree, but be careful of the falls furing rainy season, usually there is a rope across the river to prevent accidents with the deluge of water.
From Aborlan, take the road south until you reach Plaridel (about 10 kms), take a left and the road will eventually reach the seafront, hang a right then you will reach Camille Del Sur, a small resort which has overnight accommodation and other huts on the sandy beach for day-trippers. If you walk along the beach for a couple of minutes you will come to the river estuary where the water is cool for swimming.
