Morning light slants through mangrove leaves as the boat slips away from Sabang pier, leaving a polished ribbon of water that leads to a cavern mouth carved into dark limestone. The Underground River tour opens with an easy boat glide into a karst landscape—stalactites hanging like a slow-motion ceiling and bats settling into shaded niches—before the group returns inland to Ugong Rock, where community-run caving and a zipline punctuate the day.
