If you're looking to plan the perfect family vacation in Puerto Rico, a La Parguera bioluminescent bay tour should be at the top of your list of activities to do. During our recent family trip, we booked a private sunset boat charter that took us through the mangroves of La Parguera, anchored at the stunning Cayo Caracoles, and ended with a once-in-a-lifetime swim in the glowing bioluminescent waters.
Unlike the popular kayaking tours in Fajardo or Vieques, this option was kid-friendly, relaxing, and perfect for families. Here’s everything you need to know about the experience, from what to expect to how to book and what to pack.

Why We Chose a Sunset and Bioluminescent Bay Boat Charter in La Parguera
For our trip to Puerto Rico, we knew we wanted to experience both swimming in Cayo Caracoles and taking a bioluminescent bay tour, so booking a charter tour that included both made the most sense. It was a time- and money-saving option that gave us the best of both experiences in one evening.
We were traveling as a family with two kids and wanted a relaxing alternative to the typical late-night kayak tours. A boat charter in La Parguera, located on Puerto Rico’s southwest coast, allowed us to:
Enjoy a beautiful sunset at sea
Swim in the warm, shallow waters of Cayo Caracoles
Experience the bioluminescent bay without paddling or stress
Keep things easy for the kids — no kayaking, and no early-morning ferries
Plus, the town of La Parguera is charming and less touristy, which makes the experience feel more peaceful and off the beaten path.
What to Expect on a La Parguera Bioluminescent Bay Tour
We booked a Sunset and Biobay boat charter through a local tour operator, and here’s how the evening unfolded:
Departure
We left the dock around 6 PM from La Parguera marina.
The boat was private, spacious, and felt safe even with kids aboard.
The captain was friendly and knowledgeable, sharing educational facts about the area as we cruised past small cays and mangroves.
Sunset at Cayo Caracoles
The boat ride to Cayo Caracoles was smooth and took about 15 minutes.
We anchored near Cayo Caracoles, where the kids jumped in for a swim and went snorkeling.
The water was shallow, warm, and clear — perfect for floating and relaxing.
We watched the sunset over the water — easily one of the most beautiful moments of our entire trip.
Swimming in the Bioluminescent Bay: How We Planned for the Best Glow
As the sun fully set and the sky darkened, our boat took us to the glowing bioluminescent lagoon. The brightness of the glow depends heavily on the moon phase — so we planned our tour strategically.
We looked at the moon phases for the week of our trip and chose the night with the least visible moon. Although it wasn’t technically a new moon, it was a waxing crescent, and we made sure the moonrise wouldn’t interfere with our tour time. Since our charter was scheduled from 6:30 PM to 8:30 PM, I checked that the moon wouldn’t rise until after 1:00 a.m., giving us a perfectly dark sky.
Because of this, the conditions were ideal: the water glowed with every movement, and it was dark enough to fully enjoy the magical sparkle of the bay. Once in the water, the kids were mesmerized — every splash lit up with tiny blue bursts of light. It was a surreal experience we’ll never forget!
Is the Biobay Swim in La Parguera Safe for Kids?
Yes! Our kids (ages 7 and 12) felt completely safe during the swim. Here’s what helped:
Life jackets and pool noodles were available on board
The water was warm and calm
We were right by the boat the whole time.
No long paddling or strenuous activity
What to Bring for a Bioluminescent Bay Tour
Here’s what we recommend packing:
Swimsuits (wear them under your clothes)
Water shoes (some areas in the cays have rocks)
Rash guards or lightweight layers (it can get breezy)
Dry bag for phones or extra clothes
Snacks or drinks (check with your tour operator)
Where to Stay in La Parguera After Your Biobay Tour
If you're planning a La Parguera bioluminescent bay tour, I highly recommend booking a local hotel or guesthouse nearby so you don’t have to drive late at night — especially with kids.
We originally planned to stay in La Parguera the night of our tour, but I waited too long to book and most of the best hotels were already full — it was summer and high season, so availability went quickly. Since we were staying in Aguadilla, we ended up driving the 1.5 hours each way. While the tour was absolutely worth it, a local stay would’ve made the experience even more relaxing.
If you're able to plan ahead, here are some popular and family-friendly places to consider:
Tip: These hotels can book up fast during weekends, holidays, or school breaks, so make your reservations early if you're visiting during peak season.
Is the La Parguera Bioluminescent Bay Tour Worth It?
Absolutely. This was a once-in-a-lifetime experience, especially for our kids. It combined fun, learning, and natural wonder in the most beautiful setting.
Here’s why we recommend it:
No need to kayak or paddle
Family-friendly and relaxing
Unique sunset + night combo
Easier logistics than Vieques.
Private or semi-private options are available.
If you’re heading to Puerto Rico and want to do something truly magical with your family, a La Parguera bioluminescent bay tour is an unforgettable experience. From glowing waters to sunset views and the peaceful vibe of a boat ride, this is the kind of memory your kids will talk about for years.
Know Before You Go: La Parguera Bioluminescent Bay Tour Tips
Book in advance: Summer and holiday weekends fill up fast — both for tours and hotels in La Parguera. Reserve early, especially if you're traveling with kids.
Check the moon phase: Plan your tour during a new moon or a night when the moon rises late so the sky is dark enough to enjoy the glowing water.
Stay local if you can: We drove from Aguadilla, but staying overnight in La Parguera would have been much easier after a night swim. Book early to grab the best spots.
Pack smart: Bring swimsuits, towels, water shoes, and a dry bag. A light layer for the ride back and a change of clothes for the drive are also a good idea.
Kid-friendly approved: This boat charter was a great alternative to kayaking — no paddling required, and perfect for families with kids who love the water.
Happy Travels!
