Cave
Puerto Princesa Subterranean River National Park
At 8km in length, Sabang's famous underground river is one of the longest navigable river-traversed caves in the world and draws scores of tourists. Trips aboard unmotorised paddle boats proceed about 1.5km upstream into the cave (45 minutes return) and now include audioguide headsets. Book a bangka through the Sabang Information Office (P1120 for up to six people, 15 minutes) to get you from the wharf to the cave entrance, or walk 5km via the Jungle Trail.
