The Puerto Princesa Underground River, located in the Palawan province of the Philippines, is a must-visit for any traveler to the area. As part of the Puerto Princesa Subterranean River National Park, which is a UNESCO World Heritage Site and one of the New7Wonders of Nature, the underground river is one of the longest in the world. Spanning 24 km in total length and featuring an 8.2 km river, the underground river is a unique and fascinating natural wonder.

Tourists have the option to go on a DIY tour, which can save money but requires securing a permit and navigating everything on their own. Alternatively, a packaged tour is the recommended option, which includes round-trip transfer, buffet lunch, entrance fee, and a 45-minute boat tour of the underground river. The tour starts with a 2-hour drive to Sabang Wharf, where visitors will then take a 15-minute catamaran ride to Sabang Beach and the entrance to the cave.

It is important to note that there are limited permits given daily to limit the impact of tourism on the underground river, so booking ahead (at least 3 days) is recommended, especially during peak season when the tour may be fully booked. Also, children under 3 years old are not allowed for safety reasons.

The 45-minute boat tour takes visitors into the first 1.5 km of the underground river, offering a breathtaking experience of the cave system and its stunning rock formations, including stalagmites and stalactites. The clear water of the outside and the eerie yet interesting atmosphere inside the dark cave creates a truly unique and unforgettable experience. The thousands of bats that inhabit the cave add an extra element of excitement to the tour.

The Puerto Princesa Underground River Tour is a full-day experience that is well worth the time and effort. From the 2-hour drive to the 15-minute boat ride, visitors will be able to witness the beauty of this natural wonder, appreciate the stunning rock formations, and mix among the thousands of bats that call the cave home. Book ahead and be prepared for an unforgettable experience!
