Fajardo Bio Bay Kayak Tour: Night Paddle Through Laguna Grande’s Glowing Waters
Paddle through mangrove channels into Laguna Grande and watch billions of microscopic organisms light your every stroke. This two‑hour night tour combines hands‑on ecology, stargazing, and a rare bioluminescent spectacle.
The Experience
Before You Go
Book after sunset
Tours run after dark for best visibility; arrive early to complete waivers and get fitted with life jackets.
Use a waterproof case
Bring a waterproof phone case or dry bag—photos are possible but your device will get damp on the dock and in the kayak.
Mind the weight limits
Maximum individual weight is 240 lbs and combined kayak limit is 425 lbs; operators enforce this for safety and balance.
Quiet during the lagoon portion
Avoid bright lights and loud talking once on the bay—darkness and quiet improve the bioluminescence and protect wildlife.
