"Listed as one of the New 7 Wonders of Nature, the 8.2-km Puerto Princesa Subterranean River is an underground waterway with striking cave formations, underground waterfalls and abundant wildlife; the best way to experience it is by boat tour, with an official tour (about 2,200 pesos / US$43 for adults) that includes transfers, guides, entry fees and a buffet lunch." - SilverKris
