If there’s one thing you shouldn’t miss in Palawan, it’s this. The Puerto Princesa Subterranean River National Park, home to the world-famous Underground River, is both a UNESCO World Heritage Site (since 1999) and one of the New 7 Wonders of Nature (voted in 2012)—and it deserves the title.
The river itself stretches over 8 kilometers, making it one of the longest navigable underground rivers in the world. Only about 1.5 km is open to tourists, but that’s more than enough to take in the eerie beauty of the limestone cave formations, cathedral-like chambers, and occasional bats flying overhead. The ride is quiet except for your guide, who will likely point out fun rock shapes (expect references to vegetables, superheroes, and maybe even a “face of Jesus”).
The surrounding park is a protected area, covering over 22,000 hectares of forest, mountains, and rich biodiversity. It’s one of the few places in the Philippines where you can find both limestone karst landscapes and a full range of ecosystems—from mountain to sea.
To get there, you usually take a boat from Sabang Beach, then register before boarding a paddle boat into the cave. There’s also a short jungle trail option for the more adventurous. Be warned: the boat rides depend on the weather, and the road to Sabang can be a bit rough in some spots—especially if you’re prone to motion sickness.
Quick Historical Note: The underground river was known to locals long before it gained global recognition. Scientific exploration began in the 20th century, and serious conservation efforts took off when it was declared a national park in 1971. It’s now one of the most strictly protected areas in the country.
Final Thoughts:
The entire experience takes half a day, but it’s worth every minute. Between the otherworldly cave, the biodiversity of the park, and the sheer uniqueness of the place, it’s easily a top natural attraction in the Philippines.
Bring a waterproof bag, patience (especially during peak season), and a sense of wonder.
