Underground river in Puerto Princessa1
- 7 years ago
Paddling through the navigable portion of the 8.2-kilometer Underground River is a journey through time—its karstic chambers serve as a natural canvas on which vignettes of the past are geologically preserved. If you’re looking for adventure beyond Palawan’s pristine beaches, Puerto Princesa offers a regulated tour through the longest underground river in the world located 80 km north of the city.
