The day was sunny and the slender outrigger boats were bobbing in the South China Sea, their buntings fluttering while waitin for their passengers. Many tourists had arrived today at the Sabang Wharf in the barangay of Cabayugan on the western coast of Puerto Princesa City, the Capital of Palawan. The boats would sail to the Purto Princesa Underground River, a UNESCO-inscribed World Heritage site and the world's longest navigable underground river at 8.2 kilometers.
