You step off the air‑conditioned van with the heat folding around you and a green wall of rainforest rising like a live map. The road from Puerto Princesa eases into palms and limestone karst; at Sabang, wooden bancas bob in a narrow inlet, waiting to carry you toward the cave mouth. The river itself seems to breathe—dark water slipping into a throat of stone where light stops and the cave begins.
