6 Best Laguna Grande Bio Bay Tours In Fajardo (2024)

Laguna Grande 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.

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:


1. PuertoRico.com Tours – Bio Kayak Tour

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.


3. Bespoke Lifestyle Management – Rainforest and Bio Bay Combo

This Bespoke Lifestyle Management tour offers the opportunity to explore both Laguna Grande and El Yunque, two of Puerto Rico’s main attractions.
