About 3km northwest of Kabayan, near barangay Kabayan Barrio, is the Tinongchol Burial Rock, where several coffins have been leveraged into cut holes in a boulder. It's a one-hour walk along a footpath that starts behind Kabayan's national museum through stunning mountain scenery. After crossing the river, ascend the paved road; the Rock is signposted off to your left. Either get the gate key from the barangay captain or stop by with a guide en route to the Timbac Caves.
