Description
This natural beauty can be found farther down the road from Apao Rolling Hills. The highlights here are gleaming white limestone rock formations that wall the banks of the Tineg River.
How to go — From Brgy. Alaoa in Tineg, a local guide can take you across the river on a bamboo raft to Piwek Rock Formations. There are two trails to choose from. The harder yet exciting way requires a bit of rock climbing over large boulders. The easier one is a less steep hike.
