The first time I visited La Parguera, Puerto Rico, was in 2008.
When I returned eight years later, I immediately noticed something.
La Parguera had changed.
There were more businesses. More development. More activity along the waterfront. The quiet coastal community I remembered had grown.
At the time, I didn’t think much more about it.
In fact, my journal entry from that day summed up my entire historical analysis rather eloquently:
They’ve really built it up a lot.
Profound, I know.
What I didn’t understand was that I had caught a tiny glimpse of a transformation that had been underway for generations.
Long before La Parguera became one of Puerto Rico’s best-known coastal destinations—before the restaurants, boat tours, colorful waterfront casetas, and visitors coming to experience water that literally glows in the dark—it was a fishing community.
And its relationship with the sea has shaped nearly everything that happened afterward.
A Mother’s Day in Puerto Rico
My return to La Parguera happened on May 8, 2016.
Mother’s Day.
The festivities technically began around four o’clock that morning when a tropical system came through and thunder woke me up.
The storm brought enough wind and rain that my parents discovered their dog huddled in a corner of the balcony, absolutely soaked.
He had a doghouse.
Apparently, using it during a tropical storm was beneath him.
So the soggy creature was brought inside, and eventually everybody got a little more sleep.
By 6:30, I was awake for the day.
My son gave me a Mother’s Day charm bracelet that my mom had helped him put together, and we made pancakes and sausage for breakfast.
Then it was my turn to give my mom her present.
I’d created a family photo collage using photographs dating all the way back to around 1900.
She loved it.
Throughout the day, I caught her returning to it, studying the photographs and looking at generations of our family collected together in one frame.
Ten years later, that memory makes me smile for another reason.
Apparently, collecting pieces of the past and turning them into stories was already my thing.
I just hadn’t named it Travel Made Personal yet.
Returning to La Parguera
That afternoon, we got dressed up and drove to La Parguera for Mother’s Day dinner with extended family.
We ate at a restaurant owned and managed by relatives. My mom and I had steak. My son ordered pork chops. My stepdad went straight for the lobster.
There was nothing historically significant about it.
And that’s exactly why I love the memory.
We weren’t conducting research.
We weren’t trying to find a historic site.
We weren’t even there because of the natural phenomenon that makes La Parguera famous.
We were just a family having Mother’s Day dinner together.
Afterward, we walked around La Parguera.
That’s when I started noticing the changes.
My mom had brought my son and me here during our 2008 trip to Puerto Rico, and the La Parguera I was seeing in 2016 felt much more developed.
I thought it was interesting.
I took some pictures.
Then we eventually went home.
It would take another decade before I understood the story behind what I’d seen.
La Parguera Began With the Sea
La Parguera sits along Puerto Rico’s southwestern coast in the municipality of Lajas.
Long before it became a tourism destination, families settled along this coastline and built lives closely connected to the surrounding waters.
Fishing became one of the foundations of the community.
Even the name La Parguera reflects that history. It is generally associated with pargo, the Spanish name used for snapper, an important fish in the waters surrounding the village.
This wasn’t paradise being packaged for visitors.
It was home.
Families depended on fishing and small-scale agriculture. Life along the coast followed the rhythms of weather, tides, and whatever the sea provided.
By the late 19th century, when Lajas became its own municipality, La Parguera had developed an identity as one of its coastal barrios.
But those early residents were living beside something extraordinary.
Some of their water glowed.
Why Does the Water at La Parguera Glow?
One of La Parguera’s most famous natural features is Bahía Fosforescente, or Phosphorescent Bay.
The glow comes from microscopic organisms known as dinoflagellates.
When the organisms are disturbed by movement in the water, they can produce brief flashes of blue-green light.
A fish darting through the water can trigger it.
So can the movement of a boat or paddle.
Even a hand moving through the water can create flashes of light under the right conditions.
Today, we know the phenomenon as bioluminescence, and people travel specifically to Puerto Rico for an opportunity to experience it.
But imagine living beside it before the tour boats arrived.
Before travel guides advertised it.
Before photographs and videos of glowing Caribbean water could circle the world in seconds.
For generations, this extraordinary natural phenomenon was simply part of the environment surrounding La Parguera.
Eventually, however, the rest of the world started paying attention.
From Fishing Village to Tourist Destination
La Parguera’s transformation didn’t happen all at once.
During the 20th century, improvements to Puerto Rico’s transportation infrastructure made previously isolated communities easier to reach.
Scientific interest in the area grew as well.
In the 1950s, the University of Puerto Rico established marine research facilities on nearby Magueyes Island, allowing scientists to study the remarkable coastal and marine ecosystems surrounding La Parguera.
Meanwhile, visitors increasingly came to experience those ecosystems themselves.
Especially the glowing water.
Tourism created a new way for the community to make a living from the sea.
Fishermen could take visitors onto the water.
Boat tours developed.
Restaurants and other businesses followed.
More visitors meant more opportunities.
Over time, La Parguera’s relationship with the sea began to shift.
That same coastline is filled with places where Puerto Rico’s relationship with the sea has shaped its history, including Los Morrillos Lighthouse, built high above the cliffs of nearby Cabo Rojo to help guide ships through these Caribbean waters.
For generations, the water had primarily provided food and livelihoods through fishing.
Now the water itself had become an attraction.
And with popularity came development.
The Colorful Casetas of La Parguera
One of the most recognizable features along La Parguera’s waterfront is its collection of casetas.
These colorful structures sit along the shoreline and, in some cases, extend over the water on stilts.
Their history is intertwined with the area’s fishing culture. Simple coastal structures associated with fishermen eventually evolved, with some becoming larger homes and vacation properties.
They’re picturesque.
They’re distinctive.
And they’re also controversial.
As development expanded along the coast, questions emerged about permits, ownership, public access, environmental protections, and construction within a fragile coastal ecosystem.
That debate has continued for decades.
For some, the casetas are part of La Parguera’s history and cultural identity.
For others, they represent development encroaching upon an environment that desperately needs protection.
And that tension leads directly to one of the most difficult questions facing places like La Parguera.
What Happens When Paradise Becomes Popular?
There is a strange contradiction at the heart of many beautiful places.
People want to visit them because they’re extraordinary.
I saw another side of that appeal at nearby Playa Sucia, where the relatively undeveloped coastline is a huge part of what makes the beach so memorable in the first place.
But enough people visiting—and enough development to accommodate them—can threaten the very thing everyone came to experience.
La Parguera’s mangroves, reefs, channels, small islands, and bioluminescent waters form an interconnected coastal ecosystem.
That fragile relationship between land and sea continues farther west at the Cabo Rojo Salt Flats, where salt, wetlands, wildlife, and centuries of human activity have created another remarkable landscape along Puerto Rico’s southwestern coast.
Tourism also supports people who live and work there.
Those two realities don’t have to be enemies.
But balancing them isn’t simple.
How much development is too much?
How do you preserve public access while respecting generations of local culture?
How do you allow people to experience an extraordinary natural environment without slowly destroying it?
And how does a community continue benefiting economically from the sea while protecting the ecosystem upon which that economy now depends?
Those questions are much bigger than La Parguera.
They’re being asked anywhere beautiful places become popular destinations.
The Changes I Saw Without Understanding Them
None of those questions were running through my head as we walked through La Parguera in 2016.
I simply knew the place looked different than it had eight years earlier.
They’ve really built it up a lot.
That single sentence from my journal means more to me now.
I had accidentally witnessed a tiny piece of the same transformation that had shaped La Parguera for generations.
The changes between my visits in 2008 and 2016 were only the latest layer.
Before that came roads.
Tourism.
Boat tours.
Restaurants.
Scientific research.
Waterfront development.
And before all of it were fishing families who built a community beside the sea.
What Stayed With Me
Here’s the funny thing.
When I remember La Parguera, I don’t remember glowing water.
We didn’t even go see it.
I remember Mother’s Day.
I remember a storm rolling through Puerto Rico while we slept.
I remember my son giving me a charm bracelet.
I remember pancakes and sausage.
I remember my mom repeatedly returning to a collage filled with photographs of generations of our family.
I remember sitting around a restaurant table together.
And I remember walking through La Parguera afterward, realizing how much it had changed since my previous visit.
At the time, it was simply a nice day with my parents and my son.
That’s what I wrote in my journal.
And I’m glad I did.
Because places change.
People change.
Families change.
Sometimes we don’t realize we’re witnessing something that will someday become history.
A fishing village becomes a tourist destination.
A child giving his mom a Mother’s Day bracelet becomes a grown man.
A family photograph from 1900 becomes part of a collage made more than a century later.
And an ordinary walk after dinner becomes a memory you return to ten years later because you finally understand the story that was unfolding around you.
La Parguera’s story is nearly two centuries of people building their lives around the sea—and adapting as their relationship with that sea changed.
The fishermen came for what they could pull from the water.
Eventually, visitors came for the water itself.
And through all those generations of change, when darkness falls and conditions are right, microscopic organisms still illuminate the water with tiny flashes of light.
I went to La Parguera for Mother’s Day dinner.
I didn’t know I was walking through history.
Sometimes that’s exactly how history finds us.
🌊 Sometimes you don’t realize you’re watching a place change until years later.
When I returned to La Parguera, Puerto Rico, in 2016, I was there for one simple reason: Mother’s Day dinner with my family.
Afterward, we walked along the waterfront, and I remember thinking how much the little coastal community had changed since my first visit eight years earlier.
What I didn’t know was that the transformation I’d noticed had actually been happening for generations.
La Parguera grew from a small fishing village into a destination famous for water that literally glows in the dark—and its story is far more complicated than paradise postcards suggest.
