To avoid hassles, most travelers join the tour group to the Underground River. For 1500PHP /person (standard price), tour companies will secure permit to the natural park, provide lunch, provide transportation to and from Puerto Princesa City and Sabang, the motorboat ride from the Sabang port to the park/cave entrance and finally, the boat trip inside the cave. Independent travel to the park is still an option; but considering the difficulty to get to the place itself, joining the tour group isn't a bad choice.

Originally, I was afraid the place would turn out to be like Disneyland; but all in all, the site is properly managed. Sure, crowds swell at the entrance of the underground river but this is only because of the limited number of boatmen. Our tour guide also says the number of visitors per day is also being monitored within manageable level

The cave tour is a rewarding experience perhaps even for those who have joined cave explorations in the past. PPSNP did not install any colorful lighting inside and requests visitors to remain quiet. An eerie but unforgettable experience.
