Puerto Princesa: Extended Underground River Tour (up to 4km)

Exploring Puerto Princesa’s Hidden Wonder: The Extended Underground River Tour

Imagine floating through a dark, mysterious cavern that stretches for several kilometers beneath the earth, teeming with life and history. That’s the essence of the Puerto Princesa Extended Underground River Tour, a full-day adventure that lets you experience one of the world’s most incredible natural wonders. For $515 per group (up to four), you’ll spend about 10 hours exploring the world’s longest navigable underground river, with a knowledgeable guide by your side.

What we love most about this tour is how it balances authentic natural beauty with comfort and convenience. The private setup means fewer crowds and a more personalized experience, plus the inclusion of hotel transfers and a delicious Filipino lunch makes it a great value for such a unique adventure. A second highlight is the opportunity to learn about the biodiversity and ecosystems thriving in the surrounding area, giving you a deeper appreciation for this UNESCO World Heritage Site.

That said, it’s worth considering that the tour involves quite a bit of travel (about 3 hours round-trip between Puerto Princesa and Sabang Wharf), so it might not be ideal if you’re short on time or have mobility concerns. This experience suits travelers who love nature, history, and a touch of adventure, especially those eager to explore beyond the typical beach day or city tour.

In-Depth Review of the Puerto Princesa Underground River Tour

Starting Point: Comfort and Convenience from Your Hotel

The tour kicks off with a hotel pickup in Puerto Princesa, a simple way to start your day without the hassle of navigating transportation. Your guide will be waiting in the lobby about 10 minutes before the scheduled departure, setting a relaxed tone. The 1.5-hour van ride to Sabang Wharf gives you some time to appreciate the landscape and get excited about the day ahead.

Once at the wharf, you’ll transfer onto a boat that takes you on a scenic 20-minute ride across the waters. This leg is already a highlight, offering glimpses of lush surroundings and a chance to start soaking in the tropical atmosphere.

The Journey to the Heart of the Cave System

Your guide will handle all the necessary paperwork and permits, ensuring a smooth entry into the Subterranean National Park. The boat ride inside the park is where the real magic happens. Unlike regular tours that turn back after about 1.2 km, your boat will venture further into the cavern—up to 4 km—allowing you to explore more of this subterranean maze.

While standard paddle boats are often limited, your private boat offers the chance to go deeper, providing an intimate experience of the cave’s awe-inspiring formations. We loved the flexibility of the private setup, which means fewer people and more time to absorb the sights and sounds of the underground river.

Post-Cave Feast and Optional Tasting

After emerging from the underground realm, you’ll return to the wharf and then head to a restaurant near a forest park for a sumptuous Filipino buffet.
