A warm sea breeze carries the sound of distant waves as a small motorboat slips across Sabang Bay toward a jagged coastline where limestone cliffs throw long shadows on the water. The cave mouth yawns like a dark harbor, and the guide’s lamp picks out stalactites that hang like frozen drips. Inside, the river moves with a steady, patient push, ferrying visitors through chambers where light pools on mineral walls and bats lace the air with sudden motion.
