Explore one of the world's longest navigable underground rivers, the Puerto Princesa Subterranean River National Park, on this full-day trip. Benefit from hotel transfers, boat transport, lunch, and a tour guide. Experience the mysterious allure of an underwater world, hidden inside the river cave system.

Start with a morning pickup from your hotel downtown hotel in Puerto Princesa and embark on a 1.5-hour ride to Sabang Wharf. Board a motorboat to venture to the underground river. After your guide processes all the paperwork, make your way to the entrance of the cave.

While the paddle boats on regular tours return to the docks after going about 1.2 km/0.75 mi inside the cave, your boat will take you further inside this World Heritage Site. Spend up to 3 hours in the underground cavern and learn about its fascinating history.

After the tour, head back to the wharf. Stop at a restaurant near a forest park to enjoy a sumptuous feast of Filipino delicacies. If you're adventurous enough, you can try an exotic food locally called “tamilok,” a kind of woodworm freshly harvested from the nearby mangrove forest. Before heading back to the city, you can choose to drop by other community-run tourist sites in the area.
