8 Best Bioluminescent Kayak Tours In Mosquito Bay, Vieques (2024)

Vieques is an island in Puerto Rico that is home to a bio bay.

This bio bay is called “Mosquito Bay“, and you can experience it by taking a night kayak tour.

I lived in Vieques for 4 years, and I’ve seen the glowing waters of Mosquito Bay many times.

In this article, I will cover the 8 best bioluminescence tours in Mosquito Bay:


1. Glass bottom kayak tour

Exploring Mosquito Bay in Vieques on a glass-bottom kayak tour is an unforgettable experience.

This tour combines the excitement of kayaking with the experience of viewing the bioluminescent organisms in the water below while you paddle through the bioluminescent waters.

With a glass bottom kayak, you can see the bioluminescence more clearly without disturbing the organisms.

Mosquito Bay is one of three bio bays in Puerto Rico, but it is holds the title of being the brightest bay in the world.

And don’t worry, it will be dark but you’re in good hands with a guide who knows the ins and outs of the area. 

You’ll get the chance to learn about the science behind bioluminescence and how important it is to the ecosystem.

The mangroves that surround the bay are one of the reasons why this is the brightest bio bay in the world; the roots of the mangroves protect the organisms, creating a nursery for them that keeps them safe from predators.

Despite being a common misunderstanding, the primary factor that affects the visibility of bioluminescence is not the moon phase. Instead, it is the moon rise and set times that play the most important role in determining the visibility of the glow. 

While many people believe that the phase of the moon is the crucial factor, this is not usually the case.

Understanding this distinction can be crucial for those planning to witness bioluminescence, as it enables them to time their visit more accurately and increase their chances of seeing the stunning natural phenomenon in all its glory.

FAQ section:

Do you need a tour for Mosquito Bay?

Yes. The government regulates the tour companies that operate in the bay to help conserve this natural phenomenon. There is no access to the bay without a guided tour.

How do you get to Mosquito Bay?

From San Juan, you will need to drive about one and a half hours to Ceiba, where you can take a ferry to Vieques. Once you arrive on Vieques, you will take a public bus or taxi to the town of Esperanza, which is where most of the bio bay tour companies meet with their guests for the tour.


Final thoughts

Mosquito Bay is a unique experience, but it’s very hard to get to.

I recommend that you go to Laguna Grande Bio Bay in Fajardo instead, since it’s located only an hour from San Juan.
