Puerto Princesa Underground River is one of the Seven Wonders of Nature in the World. Many tourists from all over the world have visited this infamous longest navigable underground river.
Before combination of island hopping tours for joining group in El Nido are still allowed but recently local tourism banned it. But if you are in a private group, combination tours are still possible. Since we are group of 12 persons (10 adults and 2 children) we decided to avail Tour C and D for our first day in El Nido.
