Where Darkness Turns into Magic
In This Post
Into the Darkness
As we waited on the beach for our turn, I couldn't stop staring at the cave entrance.
It looked... surprisingly ordinary.
From where I was standing, it was nothing more than a dark opening carved into a towering limestone cliff. If nobody had told me what was hidden inside, I probably would have walked right past it without giving it a second thought.
And yet, that small entrance concealed one of the greatest natural wonders on Earth.
Just thinking about it gave me goosebumps.
One by one, the paddle boats slowly returned from the darkness, quietly dropping off visitors before taking a new group inside. While we waited, our guide handed each of us an audio guide headset, allowing us to choose our preferred language. She carefully checked that every device was working before helping us into the boat.
Everyone wore a life jacket and a protective helmet.
There was very little conversation.
It almost felt as though everyone instinctively understood that we were about to enter a place that deserved silence.
Our boat gently drifted away from the shore.
On one side, mangrove trees leaned gracefully over the calm river, their roots disappearing into the water. On the other, enormous limestone cliffs rose almost vertically into the sky, making me feel incredibly small.
Straight ahead was the cave entrance.
Only about 25 metres wide and 16 metres high, it seemed almost insignificant compared to the gigantic mountain surrounding it. Beyond that narrow opening, there was nothing but darkness.
No sunlight.
No colours.
Just blackness.
Slowly, our guide dipped the paddle into the water, and with each stroke we disappeared a little further into the cave.
Within seconds, daylight faded behind us.
The tropical heat remained outside.
The sounds of birds disappeared.
Only silence remained.
Broken only by the gentle splash of the paddle and the occasional drop of water falling somewhere deep inside the cave.
I have visited many beautiful places around the world.
But nothing prepared me for that feeling.
It wasn't fear.
It wasn't excitement.
It was pure awe.
Within the first few metres, I realised this wasn't simply a cave.
It was a world hidden beneath the island.
As our eyes slowly adjusted to the darkness, our guide illuminated different parts of the cave with a powerful flashlight while the audio guide explained what we were looking at.
Every beam of light revealed another masterpiece created by nature over millions of years.
Massive stalactites hung from the ceiling like giant stone chandeliers, while equally impressive stalagmites rose from the cave floor. Over thousands of years, some had grown so large that they eventually met, forming enormous natural columns that seemed to support the cave itself.
It's amazing to think that these formations grow incredibly slowly—often less than a centimetre every hundred years.
Nature has all the time in the world.
As we continued deeper into the cave, our guide suddenly gave us one piece of advice that made everyone laugh.
"Don't look up with your mouth open."
At first, I thought he was joking.
Then he pointed his flashlight towards the ceiling.
Thousands of bats.
The cave is home to several species of bats, along with swiftlets—small birds that also nest inside the cave. Every now and then, you could hear wings fluttering high above us, while tiny drops occasionally landed on our helmets.
Water...
or something else.
Let's just say I was very happy to be wearing a helmet.
The further we travelled, the lower the ceiling became in some sections. It felt as though I could almost reach up and touch the rock above us, although it was still safely out of reach. Every turn revealed new formations, each one resembling something completely different.
Some looked like giant mushrooms.
Others resembled candles, waterfalls, vegetables, or even religious figures.
The human imagination seemed to come alive inside the cave.
And then...
Everything changed.
Our little boat entered an enormous chamber so vast that I completely lost my sense of scale.
The ceiling disappeared into darkness.
No matter how hard I looked, I couldn't see where it ended.
For the first time during the entire tour, our guide stopped paddling.
Nobody spoke.
Nobody moved.
The only sound came from water dripping somewhere high above us.
The guide slowly swept his flashlight across the walls, revealing gigantic limestone formations that looked like cathedral pillars carved by nature itself.
Some visitors say this chamber resembles a cathedral.
Others compare it to a concert hall.
Standing there, I understood why.
It felt less like a cave...
...and more like nature's own masterpiece.
One after another, I could hear the same quiet reaction coming from nearby boats.
"Wow..."
Nothing else.
Just "wow."
It didn't matter what language people spoke.
That single word was enough.
It's impossible to describe the true scale of this place.
No photograph, no video, and no documentary can prepare you for standing inside it.
You simply have to experience it yourself.
As we slowly turned around and began making our way back towards the entrance, I realised something.
I wasn't just visiting another tourist attraction.
I was floating through one of the most extraordinary places our planet has to offer.
A UNESCO World Heritage Site.
One of the New Seven Wonders of Nature.
And without question...
One of the most unforgettable experiences of my life.
When Nature Leaves You Speechless
The tour lasted around 30 to 45 minutes, but it honestly felt much shorter. Every time I thought I had seen the most impressive part of the cave, another breathtaking chamber or incredible limestone formation appeared in front of me.
I found myself constantly looking in every direction, afraid that if I blinked for too long, I might miss something extraordinary. I wanted to absorb every detail, every sound, every shadow, and every moment, knowing that this was probably a once-in-a-lifetime experience.
The silence inside the cave was unlike anything I had ever experienced.
Every now and then, the only sound breaking the stillness was a tiny drop of water falling somewhere deep in the darkness. It may sound insignificant, but standing there, I couldn't stop thinking about what those tiny drops had created over millions of years.
Every stalactite hanging above my head.
Every stalagmite rising from the cave floor.
Every massive column surrounding us.
All of it had been patiently sculpted by nature, one drop at a time.
That thought completely changed the way I looked at the cave.
It wasn't just a beautiful place.
It was millions of years of Earth's history unfolding before my eyes.
There are places in the world that are beautiful because humans built them.
And then there are places like this—places where nature reminds you that no architect, no engineer, and no artist could ever create something so breathtaking.
I genuinely felt privileged to be there.
Not everyone gets the opportunity to stand inside one of the New Seven Wonders of Nature, drifting silently through a river hidden beneath a mountain while surrounded by formations that have existed for millions of years.
It was one of those rare moments that makes you stop thinking about work, deadlines, or everyday life.
Nothing else mattered.
For those few minutes, it was just me, the quiet rhythm of the paddle touching the water, and one of the most extraordinary places I have ever visited.
The audio guide also deserves a special mention. Rather than simply listing facts, it helped bring the cave to life. Every explanation gave meaning to what we were looking at, making each chamber and every rock formation feel even more remarkable. It transformed the experience from simply seeing the cave into truly understanding it.
As we slowly approached the exit, I already knew one thing.
Some experiences stay with you because they are fun.
Others stay with you because they change the way you see the world.
The Puerto Princesa Underground River did both.
Even now, as I write these words months later, I can still hear the gentle sound of water echoing through the darkness.
I can still remember looking up at that enormous cathedral-like chamber with complete disbelief.
And I can still feel the same goosebumps I felt the moment our small boat disappeared into the darkness.
Without question, visiting the Underground River wasn't just another stop on my itinerary.
It became one of the most unforgettable experiences of my entire journey through the Philippines—and one that I know I'll carry with me for the rest of my life.
Back to Reality... or So I Thought
As we stepped out of the Underground River, our group slowly made its way back along the wooden boardwalk that winds through the jungle toward the beach. The monkeys were still there, watching every visitor with curious eyes from the trees above and the rocks beside the path.
Although they looked adorable, we had been warned more than once not to get too close. These long-tailed macaques are wild animals, and while they're used to people, they can be unpredictable. They're known for grabbing food, stealing bags, and occasionally becoming aggressive if they feel threatened or spot something interesting.
It was a little disappointing because I would have loved to get closer to one of them. Seeing monkeys living freely in their natural habitat was such a special experience, and part of me wished I could have interacted with them. But respecting wildlife is far more important than getting the perfect photo. Hopefully, one day I'll have another opportunity somewhere else.
Still buzzing from everything we had just experienced inside the cave, we reached the beach where our traditional Filipino bangka was already waiting for us.
One by one, we climbed aboard, put our life jackets back on, and slowly left the shore behind.
The return journey across the bay lasted around fifteen minutes, but it felt much shorter.
A warm tropical breeze played with my hair as our boat glided across the calm turquoise water. This time, the atmosphere was noticeably quieter than before. Earlier that afternoon, everyone had been chatting excitedly, wondering what the Underground River would be like.
Now...
There was very little to say.
I think we were all still trying to process what we had just witnessed.
I certainly was.
I kept replaying every moment in my mind—the enormous chambers hidden beneath the mountain, the ancient rock formations, the silence inside the cave, the sound of water echoing through the darkness, and the feeling of floating through one of the world's greatest natural wonders.
I couldn't stop smiling.
It was one of those rare travel experiences that completely exceeded every expectation I had.
Back at Sabang Wharf, our van was already waiting for us.
We climbed back inside and began the two-hour drive toward Puerto Princesa. The journey felt much more peaceful than the one that morning. Some people looked through their photos, others quietly chatted, and a few simply closed their eyes after such an adventure-filled day.
When we finally arrived in Puerto Princesa, everyone was dropped off at their respective hotels.
I had about an hour before the evening part of the tour was due to begin.
It was exactly the break I needed.
I stretched out on the bed, gave my legs a well-deserved rest, drank some water, and let everything I had experienced slowly sink in.
At that moment, I genuinely believed the best part of the day was already behind me.
I couldn't have been more wrong.
As the sun slowly began to disappear behind the horizon, another unforgettable adventure was just about to begin.

When the Sun Went Down, the Magic Was Only Beginning
That one-hour break disappeared much faster than I expected.
Just as I was beginning to relax, there was a knock on my door.
The receptionist smiled and told me that my driver had arrived and the van was waiting outside the hotel.
I grabbed my backpack, headed downstairs, and stepped into another completely different adventure.
Unlike the Underground River tour earlier that day, this evening excursion was optional. Not everyone chooses to add the Firefly Watching & Bioluminescent Plankton Tour, and none of the people from my morning group had booked it.
Instead, I found myself surrounded by a completely new group of travelers.
Honestly, I didn't mind at all.
Travel has a funny way of bringing strangers together for just a few hours before everyone continues on their own journey.
After picking up a few more guests from other hotels around Puerto Princesa, we set off toward the river where the evening tour would take place. The drive lasted around an hour, and by the time we arrived, the sun had completely disappeared. If I remember correctly, it was around 7:00 PM.
The place immediately caught my attention.
It had a peaceful, rustic charm, with traditional Filipino-style wooden buildings beautifully lit by warm lights. The open-air restaurant overlooked the river, creating a calm and relaxing atmosphere that felt worlds away from the city.
Since other groups were still out on the water, we waited for our turn while enjoying the peaceful surroundings.
Eventually, it was time.
Because the water level was unusually low that evening, the boats could only carry three passengers and one paddler. Larger boats simply couldn't navigate the shallow sections of the river.
Our small wooden boat slowly drifted away from the dock.
Within just a few minutes, everything around us became incredibly dark.
Not city dark.
Not countryside dark.
Complete darkness.
It was my first time ever riding in a tiny boat along a river at night, and I have to admit... it felt a little intimidating.
Every now and then, our boat gently scraped the riverbed.
At first, I had no idea what was happening.
Then our paddler explained that the water was so shallow in some places that he had to carefully search for deeper channels where the boat could pass safely.
Despite feeling slightly nervous, I couldn't stop looking around.
Tiny glowing lights appeared everywhere along the riverbanks.
The fireflies.
There were hundreds of them, scattered among the trees like tiny floating stars.
Unfortunately, this is one of those experiences that no phone camera can truly capture.
No matter how many photos or videos you take, they simply don't reflect what your eyes actually see.
Sometimes the most beautiful travel memories exist only in your mind.
As we drifted farther upstream, our paddler occasionally splashed water onto the branches hanging above the river.
The moment the droplets touched the leaves...
Hundreds of fireflies suddenly began to glow all at once.
It looked as if someone had switched on thousands of tiny fairy lights hidden inside the trees.
It was absolutely mesmerizing.
I had seen fireflies before, but never in such incredible numbers and never in an environment like this.
It felt peaceful.
Almost magical.
But surprisingly...
The most unforgettable part of the evening hadn't happened yet.
As we slowly returned toward the restaurant, our paddler turned around with a smile.
"Would you like to see something special?"
"There is one more place I can take you... but it means you'll arrive a little late for dinner."
The three of us looked at each other for about half a second before answering.
"Absolutely."
Without hesitation, he gently turned the boat in the opposite direction and paddled toward a much quieter section of the river.
There were no lights.
No other boats.
Just complete silence.
After a few minutes, he stopped paddling, picked up his wooden paddle, and gently tapped the water beside the boat.
Suddenly...
The river came alive.
Thousands of tiny blue lights shimmered beneath the surface.
Every movement created another burst of glowing light.
It was bioluminescent plankton.
I had seen photos before, but nothing prepared me for seeing it with my own eyes.
It honestly felt as though someone had poured liquid stars into the river.
Every touch of the paddle, every ripple in the water, every small movement made the darkness sparkle.
I sat there completely speechless.
It was one of those rare moments when you don't even think about taking a photo.
You simply watch.
You smile.
And you realize how unbelievably beautiful our planet truly is.
We spent around fifteen magical minutes floating in the darkness, watching the water glow around us before finally heading back toward the restaurant.
By the time we arrived, most of the other guests had already finished eating.
Not once did I regret staying longer on the river.
I would happily skip dinner all over again for another chance to witness something so extraordinary.
Thankfully, there was still plenty of delicious Filipino buffet food waiting for us, and after such an unforgettable evening, every bite tasted even better.
Soon afterward, we climbed back into the van for the final drive to Puerto Princesa.
One by one, everyone was dropped off at their hotels until it was finally my turn.
I walked back to my room, took a long shower, and lay down on the bed with a smile I simply couldn't hide.
That day had given me more unforgettable memories than I could have imagined.
The Underground River.
The mangroves.
The monkeys.
The zipline.
The fireflies.
The glowing plankton.
As I lay there thinking about everything I had experienced, I felt overwhelmed with gratitude.
So many people spend their entire lives without ever leaving their hometown.
Some never even leave their own country.
Yet somehow, life had given me the opportunity to travel to the other side of the world, to witness places I had only ever seen in documentaries, and to experience moments that I know I will remember forever.
I fell asleep with a grateful heart and an enormous smile on my face.
Because when I woke up the next morning...
A brand-new adventure was waiting.
It was finally time to leave Puerto Princesa behind and begin my journey to El Nido—a destination I had dreamed about for years, and one that would soon steal a piece of my heart. 🌴✨
