Starting Point and Logistics

The adventure begins at Mareaito Charters in Lajas, a small town well-known for its scenic coastal views and accessible boat tours. The meeting point is straightforward, and with a mobile ticket, the check-in process is smooth. The tour lasts roughly 2 hours, making it easy to fit into a day of exploring Puerto Rico. Given the max group size of 13 travelers, it feels intimate enough to ask questions and get personalized attention from guides.

The Itinerary: From Sunset to Bioluminescence

The tour kicks off about 30 minutes before sunset, allowing you to settle on the boat and enjoy the anticipation of the approaching dusk. The first stop is a sandbar—a peaceful spot where you can swim, snorkel, and watch the sun dip below the horizon. Many reviewers mention the warm water and crystal-clear visibility, ideal for snorkeling with tarpon or just floating with floaties provided. One reviewer noted, “the water was super warm in the bay and the glow was very cool,” highlighting how comfortable and engaging this part of the trip can be.

As you relax on the sandbar, you’ll experience a beautiful sunset—a perfect backdrop for photos and quiet reflection. The guides are known to be very knowledgeable, sharing local insights and making sure everyone feels comfortable in the water.

After sunset, the boat moves to the bioluminescent bay. This is the star of the tour—an environment where tiny phytoplankton emit light when disturbed, creating a sparkling, almost magical display. Swimmers can enter the water, and many reviews describe this as a “once-in-a-lifetime” chance to see nature’s light show up close. The water is warm and calm, with the glow reacting to movements and allowing you to “play with pixie dust,” as one reviewer put it.

What Makes This Tour Special?

Unlike other bioluminescence experiences, this tour allows swimming in the bay, not just gazing at it from a kayak or boat. Several reviews emphasize the fuller experience of swimming in the glowing water, stating, “if you go, be sure to get in the water otherwise you don’t get the full effect.” You’ll love the way the water sparkles as you move, creating a surreal, almost alien environment.

The guides and captain are recognized for their friendly, professional demeanor, ensuring safety and a smooth experience. One review mentions, “Brian was a great captain, friendly and knowledgeable,” which adds to the overall sense of trust and comfort.

Equipment and Comforts

The tour includes floaties, making floating and relaxing in the water easy, especially for those not comfortable swimming. However, towels and snorkeling gear are not included, so bring your own if you want to snorkel or dry off afterward. A common suggestion from reviewers is to bring towels and plenty of water—the warm water makes it tempting to stay longer.

An important point for some travelers: the lack of on-site amenities like bathrooms or changing rooms. While this doesn’t seem to detract from the overall enjoyment, it’s worth considering if you prefer more facilities or plan to change clothes afterward.

Duration and Price: Is It Worth It?

For $65 per person, the tour provides a well-paced 2-hour experience that covers both sunset and bioluminescent bay experiences. The reviews consistently praise the excellent value, highlighting the quality of guides, the beautiful scenery, and the unique opportunity to swim in such an environment.

The price is particularly reasonable considering the rarity of the experience. Many travelers who have done similar tours elsewhere say that the swimming aspect sets this apart from kayak or boat-only options.

Environmental and Safety Considerations

The tour’s emphasis on ecological preservation is evident, with the bioluminescence being a living environment sensitive to environmental conditions such as weather, tides, moon phases, and currents. The guides always prioritize safety, making sure everyone is comfortable in the water and aware of their surroundings.

Most reviews reflect satisfaction with safety protocols, and the maximum group size of 13 ensures a personalized and secure experience.

Who Will Love This Tour?

This tour is perfect for families, couples, or solo travelers seeking an authentic interaction with nature. It’s especially suited for those who want to swim in the bay rather than just observe from a boat. If you’re interested in stunning sunsets combined with a magical bioluminescent display, this tour checks both boxes.

Travelers who appreciate knowledgeable guides, value excellent customer service, and enjoy relaxing boat rides will find this a rewarding experience. Active travelers or those with moderate physical fitness will be comfortable in the water, though non-swimmers can still participate with the provided safety equipment.
