6 Best Bioluminescence Tours In La Parguera Bio Bay, Puerto Rico (2024)

Puerto Rico has three bioluminescent bays.

La Parguera Bioluminescent Bay is the only one you are allowed to swim in.

I first visited this bio bay when I was a child, and I have taken these tours at least a dozen times since. 

Below are the 6 best tours in La Parguera:


1. Glass bottom catamaran tour

As the name says, this is a catamaran with a glass bottom.

A glass bottom catamaran tour of the bio bay is perfect for seniors and small children.

On this tour, you don’t get to swim in the bioluminescent bay.

When you arrive at the bioluminescent bay, the captain briefly explains the bio bay. Then, they collect a bucket of water, and you can agitate the water with your hands to activate the bioluminescent organisms.

After that, they send some crew members to swim under the catamaran. As the crew members agitate their arms and legs, you can see how the water starts to illuminate through the glass bottom.

This tour is excellent and inexpensive, perfect for the elderly and younger family members. 

You can book this tour with the Fondo de Cristal Tour.


2. Bio bay swimming tour

La Parguera Bioluminescent Bay is the only bio bay in Puerto Rico where you are allowed to swim.

At La Parguera, you have the opportunity to swim with Bioluminescence, an experience not offered at any other bay in Puerto Rico.

Some tours allow you to get in the water and activate the bioluminescence yourself by moving in the water.

The tour operator will take you on a boat to La Parguera’s Bioluminescent Bay.

You will get a brief explanation of what makes the water glow, and then you will swim in the bio bay, spending about an hour in the water.

This tour is physically demanding, but if you can swim, I highly recommend it.

3. Snorkeling and bioluminescent bay tour

They call this tour the best of both worlds.

At 4:00 PM, they take you to snorkel some of the best shallow reefs in Parguera. A PADI professional will accompany you on the trip to ensure your safety.

At 6:00, they will serve you Puerto Rican empanadas and your choice of soda or local beer. After you have eaten, they will take you on a boat to the bioluminescent bay.

At the bio bay, they will provide you with a mask and a snorkel.

This tour lasts half an hour and allows you to experience bioluminescence with an underwater view.

4. Nightime bio bay kayak tour

The tour operators will provide you with a life vest, a glow stick, and a sound device.

You will be allowed to go in the water and swim in the bioluminescent bay. These tours take two hours from start to finish.

Taking a private bioluminescence tour can be the perfect option for groups or couples.

This tour has a six-passenger maximum. The tour operator will take you to bio bay in a 19-foot boat. You are allowed to swim so you can experience it firsthand.

Tours use a skiff which is a shallow, flat-bottomed open boat with a sharp bow and square stern.

The US Coast Guard regulates all marine vessels, and they have the following regulations: 

The maximum weight the boat can carry is 1,400 pounds. The ladder to get in and out of the boat might not hold more than 250 lbs.
