The Puerto Princesa Subterranean River is one of the most extraordinary natural experiences in Southeast Asia. A UNESCO World Heritage Site and one of the New Seven Wonders of Nature, this underground river flows through a cathedral cave system for 8.2 km before emptying into the South China Sea. Here is everything you need to know to visit in 2026.
Quick Answer
The Puerto Princesa Underground River is 81 km from the city in Sabang. Day tours cost ₱1,200 to ₱1,500 per person including transport, permit, and boat. Book your permit at least 2 to 3 days in advance during peak season. The boat tour inside the cave takes 45 minutes.
What Is the Underground River?
The Puerto Princesa Subterranean River runs underground through a massive limestone cave system. The cave is navigable by paddle boat for 4.3 km of its total 8.2 km length. Inside, dramatic stalactites and stalagmites form enormous chambers — some as large as sports stadiums — with bats swooping overhead and a river running silently beneath you in the darkness.
The cave also opens directly onto a beach where the river meets the South China Sea — a setting that is genuinely unlike anywhere else in the world.
How to Book — Permit Requirements
The Underground River limits daily visitors to protect the cave ecosystem. You need a permit to enter and permits frequently sell out days in advance during peak season.
- Online permit booking: Book your permit at the official Puerto Princesa City Tourism website or through your hotel’s tour desk. Online booking is strongly recommended — walk-in permits are limited and often not available during busy periods.
- Day tour through a local agency: Most travelers book a full day tour that includes transport from Puerto Princesa city, the cave permit, a guide, the boat ride, and lunch at Sabang. This is the simplest option and costs ₱1,200 to ₱1,500 per person.
- DIY: Arrange your own transport to Sabang (₱300–400 by van shuttle), pay the entrance fee and permit at the park, and join a boat group at the cave entrance. Cheaper but requires more planning and the permit must still be booked in advance.
What the Tour Includes
- Round trip transport from Puerto Princesa city to Sabang
- Entrance permit to the Underground River National Park
- Paddle boat ride through 4.3 km of the cave
- Audio guide provided at the cave entrance
- Guide at key points inside the cave
- Lunch at Sabang (most full day tours)
- Free time at Sabang beach before and after the cave tour
What to Bring
- Headlamp or torch — the cave is very dark and the boat’s light illuminates only a small area at a time. Your own light lets you look in all directions.
- Waterproof bag — bats live in the cave. They occasionally drop guano on visitors and their belongings. A waterproof cover for your bag is strongly recommended.
- Hat — same reason as above.
- Closed shoes or sandals with straps — the beach at Sabang has rocks and the boat boarding area can be slippery.
- Sunscreen and swimming gear — Sabang beach is beautiful and many visitors swim before or after the cave tour.
- Cash — bring ₱500 to ₱1,000 extra for drinks, snacks, and tips for your boat paddler.
How to Combine the Underground River with Your El Nido Transfer
Most travelers fit the Underground River into a 2-night Puerto Princesa stay before heading to El Nido:
- Day 1: Arrive Puerto Princesa, check in, rest
- Day 2: Underground River full day tour
- Day 3: Morning van transfer to El Nido (book for 7:30 AM or 9:30 AM departure)
This gives you a full day at the cave without rushing and still puts you in El Nido by early afternoon on Day 3 with plenty of time to settle in before your first island hopping tour.
Book your Puerto Princesa to El Nido van transfer in advance — morning departures fill up, especially during peak season. Book here or WhatsApp us at +63 948 108 7090.
