You step off the van in Sabang and the air changes—thick with wet limestone and the salt of a nearby sea. Local boats wait on a narrow river that threads through mangroves, and your guide points to a cave mouth where darkness seems to inhale itself. The boat slips forward; stalactites hang like the teeth of some slow-moving beast, and the river, almost black, carries the sound of voices and drip after drip into the cavern’s hush.
