Detailed itinerary

1

At the dock, a certified USCG captain awaits with your pontoon boat — chosen for its comfort, stability, and enhanced bioluminescence visibility. After a brief safety orientation, you’ll cruise toward a paradisiacal cay nestled in crystal-clear, waist-deep waters, ideal for gentle, stress-free snorkeling and floating. Families find joy in the playful ease of it all. Couples share a golden horizon in quiet intimacy and wonder. Seniors float effortlessly, without needing to exert themselves, with beauty and ease.

At the Cay, Carlos Alexis will show you around the surrounding channels, where the gentle current behaves like a lazy river. He’ll even take you snorkeling to the back of the cay using our hypoallergenic silicone gear while the sun still shines through the mangroves — always making sure you stay safe and secure. As golden light shimmers on the water’s surface, the sun dips below the horizon as Mother Earth’s prelude to her most magical act and the night’s main attraction.

2

As night falls, your boat drifts into Papayo Cove, where Carlos Alexis begins with a historical and scientific briefing about the bay, and the real stars of the show: the dinoflagellates. Then, he leads the way into the water that appears still and dark — until he touches it. Then… it glows!

He will teach you how to elicit the glow so the bioluminescence reaches its full peak. Once you’ve mastered the glow, he gently guides you under the boat’s deck, where the glow intensifies, revealing the full magic of this sacred bay.

Once you feel confident and safe, Carlos returns aboard the pontoon and transforms into your filmmaker and director, using the ultimate tool to capture this elusive phenomenon: Sony’s advanced ZV-E1 AI camera system. He documents your interaction with the dinoflagellates — a sacred, cinematic encounter captured in a way only he can.

Whether you see it as a scientific marvel, nature’s magic, or a divine encounter, you’ll feel changed — reborn by water and wonder.

Back on shore, your dinner awaits — warm, fresh, and locally inspired. You’ll change into dry clothes, share laughter after your surreal and magical experience, and savor the flavors of Puerto Rico, thoughtfully served at a table reserved just for you, giving you a chance to digest the night’s unforgettable magic.

After dinning, the return drive is peaceful. Children drift to sleep with smiles, still glowing from the bay. Couples sit hand-in-hand in silence, still glowing inside. And seniors rest deeply, their hearts full and content knowing they’ve lived something few ever will. As you arrive back at your hotel, your footage is safely backed up. And in just a few days, you’ll receive a professionally edited cinematic keepsake of your bioluminescent swim — one of the rarest and most beautiful moments a traveler can capture anywhere in the world.
