Discover one of the Philippines’ most extraordinary natural wonders: the Puerto Princesa Underground River. This UNESCO World Heritage Site and one of the New Seven Wonders of Nature offers an enchanting experience of exploring a subterranean river that flows directly beneath the stunning limestone karst landscape of Palawan. If you’re planning to visit this iconic site, this guide will walk you through everything you need to know about booking a tour, what to expect during your adventure, and essential tips to make the most of your visit to the Puerto Princesa Underground River.
Introduction to the Underground River
The Puerto Princesa Underground River, also known as the Sabang River, stretches for approximately 8.2 kilometers, with about 4.3 kilometers navigable by boat. Flowing through a massive limestone cave system, the river leads to areas of remarkable rock formations, wildlife, and ancient stalactites and stalagmites. Part of the larger Puerto Princesa Subterranean River National Park, this site is celebrated not only for its natural beauty but also for its ecological significance, housing diverse flora and fauna both inside and outside the cave. A visit here is truly like stepping into another world—a peaceful, mystical realm carved by millions of years of natural processes.
How to Book a Tour and What’s Included
Booking a Puerto Princesa underground river tour is straightforward, but it’s best to plan ahead, especially during peak travel seasons (November to May). Tours can be arranged through various operators online, through your hotel, or at local travel agencies in Puerto Princesa City. Most tours include:
- Round-trip transportation from Puerto Princesa to Sabang Wharf
- Permit fees and environmental entrance fees to the Underground River National Park
- A guided boat tour through the cave
- A visit to nearby attractions such as the Sabang Mangrove Forest or zipline activities (depending on the package)
- Sometimes lunch or snacks
It’s important to book tours from accredited operators to ensure you comply with environmental guidelines and for your own safety. Day tours usually start early in the morning to avoid the crowds and make the most of your day.
What to Expect on the Boat Ride and Cave Exploration
Your adventure begins with a scenic boat ride from Sabang Wharf to the cave entrance. The short journey offers stunning views of the thick mangroves and coastal landscape. Upon arrival, a small paddle boat will take you inside the massive cave itself. The entire cave is illuminated by your guide’s flashlight, revealing impressive limestone formations along the walls and ceiling, underground chambers, and a mysterious, almost otherworldly atmosphere.
The guide will narrate fascinating details about the cave’s geology, history, and the creatures that call it home, such as bats and swiftlets. The boat ride through the underground river takes around 45 minutes to an hour. It’s a serene and humbling experience, perfect for nature lovers and adventure seekers alike.
Tips for Timing and Weather
Timing your visit can significantly affect your experience. The best months to visit are during the dry season from November to May, when the sea is calm, and the caves are more accessible and safer for exploration. The rainy season (June to October) can cause rough waters and occasional closures due to flooding risks in the cave.
It’s advisable to arrive early in the morning as tours start as early as 7:30 AM, which helps you avoid large tour groups and enjoy a more peaceful exploration. The site can get busy around midday, especially on weekends and holidays.
Safety Guidelines and Accessibility
The Puerto Princesa Underground River is generally safe for visitors, but following certain safety guidelines ensures a smooth trip:
- Listen carefully to your guide’s instructions, especially inside the cave where footing can be slippery.
- Wear life jackets during boat transfers and cave rides—they are mandatory.
- If you have mobility issues, inform the tour operator before booking. The site offers some accessibility accommodations, but the terrain and boats may still pose challenges.
- Avoid touching the cave walls or formations to help preserve the fragile environment.
Tour guides are trained to prioritize safety and environmental care, making your experience both secure and respectful to the natural site.

Photography Tips
Capturing the beauty of the Puerto Princesa Underground River can be challenging due to low light inside the cave and the movement of the boat. However, with some preparation, you can bring home stunning photos:
- Use a camera or smartphone with good low-light capabilities or manual settings.
- Consider bringing a compact tripod or stabilizer to minimize shake from the boat’s movement.
- Turn off your camera’s flash to avoid disturbing wildlife and to maintain the natural mood of the cave.
- Focus on wide shots to capture the grandeur of the cave formations and intimate close-ups of textures and patterns on the rocks.
- Early morning light outside the cave provides the best conditions for landscape shots as you travel to and from Sabang Wharf.
Remember, the most memorable moments often go beyond the lens, so strike a balance between taking photos and immersing yourself in the experience.
