The van eases out of Puerto Princesa before dawn and the road becomes a ribbon through palms and limestone ridges. Wind-bent trees lean as if pointing the way north; fishermen on the shoreline wave sleep from their small banca boats. After an hour or two the pace changes — the air smells of mud and salt, the mangroves grow thick, and a cluster of karst towers appears like weathered sentries guarding the river entrance. This is Sabang, and the underground river waits.
