3D2N Puerto Princesa with Underground River

The cave that made the list. Puerto Princesa’s Underground River is one of the largest cave systems on earth — a river running 8.2 kilometers through a limestone mountain, navigable by boat deep into the dark, with chambers big enough to swallow a cathedral. It’s a UNESCO World Heritage Site and one of the New 7 Wonders of Nature, and unlike Coron and El Nido, PPS keeps its jet service from NAIA — the easiest Palawan gateway there is.

The land package covers three days and two nights on your dates, with the Underground River as the centerpiece and the city’s famous seafood market for the evenings. Solo or share per person, confirmed at booking.

More add-on tours — joiners basis, per person, city-centre hotels; rates move with the season, so the desk quotes today’s fare at booking:
