The Famous Underground River! One of the latest entries at 7 Wonders of the World. It was a superb experience! I am so impressed on how people of Palawan preserve this spot. Seeing it real was a goosebumps!
Subterrenean River is the best! We were running out of our budget on the day we went here but we did not miss the chance of visiting this spectacular place at Palawan. WORLD CLASS! :-)
