Have a full-day tour of Puerto Princesa's major attractions and enjoy three highlights.
Visit its navigable underground river with spectacular rock formations, stalactites, and stalagmites, which has been declared a UNESCO World Heritage Site. Awarded as a RAMSAR Site, this 8.2-kilometer-long underground river is known to be the longest navigable in the world and is now one of the 7 wonders of nature.
You will also visit the caves of Ugong Rock in the town of Tagabinet where the cave covers the first kilometre of the river. The last part of the tour will make you boost your adrenaline with a zip line ride.
