Some travel experiences sound almost too magical to be real.
Kayaking through a Puerto Rican mangrove at night and watching the water glow around your paddle? That was definitely one of them.
So, naturally, we put a bioluminescent bay on our Puerto Rico itinerary.
What we didn’t realise was that our youngest daughter was going to have some very strong opinions about the lighting.
“I NEED LIGHT!”
Our bioluminescent kayak tour started by paddling through the mangroves towards Laguna Grande in Fajardo.
It was getting darker and darker as we made our way through the narrow waterways.
Beautiful, right?
Well… not according to our youngest.
She couldn’t see much around her and wasn’t particularly impressed with the whole kayaking through the darkness concept.
And then came the sentence that would become the highlight of the evening:
“I NEED LIGHT! I CAN’T SEE!”
We tried to reassure her.
We explained that it was supposed to be dark.
We reminded her that we were heading towards something that could only really be seen in the dark.
I’m not sure how convincing we were.
But eventually, we reached the lagoon.
Surely this was going to be the magical part.
Except… it was still too light
We had finally arrived at the bioluminescent bay, but there was one problem.
It wasn’t dark enough.
The guides were trying to find the darkest possible spot, but there was still too much light around us.
So what did we do?
We hid underneath a tarp.
Yes.
Four people in kayaks, underneath a giant tarp, trying to block out the remaining light so we could see the bioluminescence.
And suddenly our youngest daughter’s earlier complaint seemed rather funny.
First she had been shouting:
“I NEED LIGHT!”
Now we were all sitting there thinking:
“Actually… we need less light.”
The glow we barely saw
Eventually, we started to see tiny flashes in the water.
When we moved our hands or paddles through it, there were little sparkles.
But honestly?
We barely saw the bioluminescence.
The conditions just weren’t on our side that evening. Bioluminescence is best viewed when the surrounding conditions are as dark as possible, and although our guides did everything they could, it simply wasn’t dark enough for us to experience the spectacular glowing-water effect we had imagined.
And that meant something else.
We have no photos.
None.
It was too dark for our phones to capture anything useful, while at the same time not being dark enough for us to properly see the glow.
A little ironic, really.
We had travelled all the way to a bioluminescent bay and came home without a single decent photograph of it.
Would we do it again?
Honestly, I’m glad we went.
Was it the incredible glowing-water experience we had imagined from the photos online?
For us, no.
We barely saw it.
But that’s also why I’d recommend going with realistic expectations. The photos you see online can make it look as though you’ll be paddling through an intensely glowing blue lagoon.
It can be spectacular, but the experience depends on darkness, weather, water conditions and the natural concentration of the microorganisms.
So don’t book it expecting a guaranteed Instagram moment.
Book it because kayaking through a mangrove at night and searching for glowing water is an adventure in itself.
And if you’re travelling with kids, prepare them for the darkness beforehand.
Although, in our case, I’m not sure anything would have prepared our youngest for the irony of the evening.
She started the tour desperately needing more light.
She ended it sitting underneath a tarp because we needed less.
That’s family travel for you.

Our Puerto Rico adventure
The bioluminescent bay was just one part of our Puerto Rico adventure.
We travelled around the island with our girls, combining cities, beaches, rainforest and plenty of family adventures.
If you’re planning a similar trip, start with our Puerto Rico with Kids: San Juan, Fajardo, El Yunque & Rincón – The Ultimate Island Itinerary, where we share our complete route around the island.
And if you want another taste of our slightly chaotic family adventures, read El Yunque with Kids: Chasing Waterfalls in Puerto Rico’s Rainforest. That’s where you’ll find more of our rainforest adventures — and where the first “I NEED LIGHT!” moment began.
Because sometimes the moments that don’t go quite according to plan end up being the ones you remember most.
