The night opens like a slow breath over Laguna Grande: paddle tips carve bright streaks in the black water, and each dip lights up with a sudden, electric blue. On a guided tour you sit low in a rental kayak, eyes adjusting, ears tuned to the hush of mangroves and the paddle rhythm that coaxes dinoflagellates into glowing.

Reserve your spot on the Bioluminescent Bay Night Kayaking, Laguna Grande, Fajardo today and enjoy a trusted, highly rated experience designed to help you make the most of your adventure.
Use a red-filter headlamp
White light destroys night vision and ruins bioluminescence—bring a red-filter headlamp or ask your guide for one.
Choose reef‑safe sunscreen
Apply biodegradable, reef‑safe sunscreen before launch to avoid contaminating the lagoon with toxins.
Dress for humidity and splash
Wear quick‑dry layers and secure straps—nights are warm but you’ll get wet when paddling and entering/exiting the kayak.
Leave electronics sealed
Waterproof cases for phones and cameras keep equipment safe and reduce temptation to splash or shine lights into the water.
Red-filter headlamp
Preserves night vision and avoids washing out bioluminescence while providing just enough light for safety.
Waterproof phone case
Keeps electronics dry and prevents accidental light exposure that would diminish the experience.
Closed-toe water shoes
Provide grip and protection for shallow launches and rocky or muddy shorelines.
Reef-safe sunscreen
Protects your skin while avoiding chemicals that harm the bay’s ecosystem.
