6 Best Bioluminescence Tours In Laguna Grande Bio Bay – Fajardo, Puerto Rico (2023)

Laguna Grande Bio Bay is one of three bio bays in Puerto Rico.

It is located in Fajardo, which is only an hour drive from San Juan, the capitol of Puerto Rico. If you want to see the brightest bio baby in Puerto Rico, visit Mosquito Bay in Vieques.

I’ve been to Laguna Grande Bio Bay, and can confirm that this is a magical experience that you must do. 

In this article, I will cover the 6 best bioluminescence tours in Laguna Grande Bio Bay:


1. Kayaking Puerto Rico – Bio Bay Kayak Tour

The Bio Bay Kayak Tour in Fajardo is one of the top-rated tours to Laguna Grande.

Visiting by kayak is the most interactive and fun way to experience the bay for water sport lovers and kids.

This tour includes: 

  • A certified local guide
  • Basic kayaking lesson
  • Kayaking through the red mangrove forest
  • Seeing the bio bay
  • Low-intensity night lights
  • Snacks


The tours start before nightfall, so you can easily navigate the mangrove forest in the canal and see where you’re going.

Even if you aren’t allowed to swim in the bay, prepare to get soaked while paddling.

2. BioIsland Tours – Bio Bay in Boat

One of the least-known ways to visit the bay is by taking a boat tour with Bio Bay Island Tours.

Exploring the bio bay by boat makes it easy to relax and take photos during the experience.

On this tour you’ll:

  • Navigate through the red mangrove forest
  • Hear a local explain how the ecosystem in the bay works 
  • Receive a long pole to agitate the water from the boat
  • See night constellations


Visiting by boat tour is the best and safest way to visit with kids and the elderly. It’s also pretty easy to take pictures without worrying about your kayak tipping over. 

The only downside it’s they only operate from Monday to Thursday. If you’re visiting on the weekend, you’ll have to choose another tour.
