Puerto Princesa Underground River Guide for Tourists

To visit the Puerto Princesa Underground River, you must book a tour in advance to secure a limited-entry permit, travel to Sabang Wharf from the city center, and take a motorized boat followed by a guided paddle boat into the cave system. It is highly recommended to book through a licensed agency to handle the logistics, environmental fees, and transportation seamlessly.

The Magic of the Underground River

Alam niyo ba, the Puerto Princesa Subterranean River National Park is not just a local treasure, but a UNESCO World Heritage site and one of the New 7 Wonders of Nature? Located about 80 kilometers north of Puerto Princesa City, this 8.2-kilometer navigable underground river flows directly into the sea. For us Pinoys, especially those coming home for a vacation or OFWs bringing their families, this is a bucket-list destination that makes you proud of our natural beauty.

Inside the cave, you’ll see massive chambers, intricate stalactites, and stalagmites that look like everything from religious figures to vegetables (the famous "cacao" or "corn" formations). The experience is quiet, serene, and slightly eerie in the best way possible. But before you get to the cave, there’s a bit of planning to do to make sure your trip is "smooth sailing."

Planning Your Trip: Permits and Logistics

The most important thing to know is that you cannot just show up at the cave. The government limits the number of visitors per day to protect the ecosystem.

1. Book in Advance: Usually, your hotel or a local tour operator will handle the permit for you. If you are a DIY traveler, you need to visit the Underground River Booking Office at the City Coliseum in Puerto Princesa City. However, for most travelers, booking a package tour is much more convenient.
2. Environmental Fee: Make sure to keep your "Eco-ticket" receipt. This is often included in tour packages, but it’s good to double-check.
3. Identification: Bring a valid ID (Passport for OFWs or UMID/License for locals). They are strict about matching the name on the permit to the person entering.

How to Get to Sabang from Puerto Princesa City

The journey starts in the city. You have a few options to get to Sabang, the gateway to the river:

• Van for Hire: This is the most common way. It takes about 1.5 to 2 hours. The roads are winding but paved, offering beautiful views of the Palawan countryside.
• Public Bus/Jeepney: For the ultra-budget traveler, there are buses from the San Jose Terminal. It’s cheaper but takes longer and follows a strict schedule.
• Private Car: If you’re traveling with a big family, renting a private van is the most comfortable way to go.

Once you arrive at Sabang Wharf, you’ll wait for your turn to board a motorized banca that takes you to the entrance of the cave. This is where the real adventure begins! While waiting at the wharf, you’ll want to share your "OOTD" or the beautiful beach views with your friends. This is why having reliable data is a must.

Staying Connected: Why You Need Data in Palawan

Palawan is beautiful, but let’s be real—the signal can be "kuripot" in some areas. When you’re at Sabang Wharf or heading back to the city, you’ll want to check your Messenger for messages from family, look up the best places to eat in Puerto Princesa, or post your IG stories.

Roaming with your international SIM can be incredibly expensive. Why pay for a "gold-plated" roaming bill when you can get mura data? BalikData offers affordable eSIM plans that use the best local networks, SMART (5G) and Globe (5G). Whether you are an OFW visiting from the Middle East or a traveler from Manila, staying connected shouldn't break the bank. You can see plans that fit your specific stay, whether it's a quick weekend getaway or a long month-long exploration of Palawan.

Coverage Realities in Palawan

In Puerto Princesa City, both Globe and Smart have excellent 5G and 4G coverage. However, as you head towards Sabang and the rural areas, the signal can fluctuate. Having an eSIM that can tap into these networks ensures you have the best possible chance of staying online. Since our plans are data-only, you don’t get a local number, but you can use WhatsApp and Messenger calls to talk to anyone, just like you do at home.

Comparing Connectivity: BalikData vs. Traditional Roaming

Many travelers wonder if they should just stick to their home SIM's roaming. Here is a quick comparison to help you decide:

Feature	Traditional Roaming	BalikData eSIM
Cost	Usually very high daily rates	Mura and fixed price
Convenience	Automatic but expensive	Easy digital install
Network	Limited to one partner	Access to Smart & Globe 5G
Local Number	Your home number	No local number (Data only)
Control	Risk of "bill shock"	Pre-paid, no hidden fees

If you're still using an older phone, make sure to check if your device is eSIM compatible before you buy. For those with the latest tech, you can read our guide on how to setup BalikData eSIM on iPhone 14 to get started in minutes.

Data Needs by Activity

How much data do you actually need for a Palawan trip? Here’s a rough guide:

• Google Maps/Waze: Navigating the city or finding your way to restaurants uses about 50MB per hour.
• Social Media Posting: Uploading high-res photos and videos to TikTok or Instagram can eat up 100MB-500MB quickly.
• Messenger/WhatsApp Calls: A 10-minute video call to your family abroad uses about 150MB.
• Streaming: If you’re watching Netflix in your hotel room, that’s 1GB+ per hour.

For a 3-day trip, a 3GB plan is usually enough for basic social media and maps. If you’re a heavy user or staying for 2 weeks, our 10GB or 20GB plans are much better value. You can always top-up if you run out, so no need to worry! Check out our see plans to find the right balance for your budget.

Step-by-Step: Setting Up Your Travel eSIM

Setting up your connection is easier than ordering Jollibee on an app. You don't need to find a physical store at the airport or swap out your tiny SIM card (na baka mawala pa!).

1. Purchase: Choose your plan on BalikData.
2. QR Code: You’ll receive a QR code via email instantly.
3. Scan: Go to your phone's Settings > Cellular/Mobile Data > Add eSIM, then scan the code.
4. Activate: Follow the prompts to label your new plan. You can learn more about the specific steps in our guide on how it works.

Travel Tips for Your Underground River Adventure

To make the most of your tour, keep these tips in mind:

• Wear Slippers or Aqua Shoes: You will be walking through shallow water to get to the paddle boat. Don’t wear your fancy sneakers!
• Protect Your Gear: Bring a dry bag for your phone and camera. The cave can be drippy, and there’s always a chance of a splash on the boat.
• Don't Open Your Mouth: Look up, but keep your mouth closed! There are thousands of bats in the cave, and "guano" (bat droppings) is a real thing.
• Be Quiet: The guides use a low-decibel audio guide system to avoid disturbing the wildlife. Respect the silence of the cave.
• Watch Out for Monkeys: At the entrance, there are wild macaques. They are cute but experts at stealing food and shiny objects. Keep your bags zipped!

The bottom line

Visiting the Puerto Princesa Underground River is a proud moment for any Filipino traveler. It’s a world-class destination that deserves a spot on your itinerary. By booking your permits early and securing a mura data plan from BalikData, you can focus on the beauty of the cave without worrying about how to get home or how much your roaming bill will cost. Stay connected, stay safe, and enjoy the beauty of Palawan! Solo flight man o kasama ang buong pamilya, connectivity is key to a stress-free bakasyon.
