What Travellers Say
Reviews Summary
Visitors consistently describe the bioluminescence tour at Manialtepec Lagoon as a magical and unforgettable experience. The glowing waters create a surreal, almost primeval atmosphere, enhanced by the pristine natural landscape. While the phenomenon itself is breathtaking, the quality of the guide can significantly elevate the experience, with passionate naturalists bringing the area to life with science and stories.
"This excursion was truly unforgettable — a magical experience from start to finish — and much of that is thanks to our wonderful guide, Alexis.
The setting itself is breathtaking: a completely untouched landscape where trees with roots plunging into the water form a surreal, almost primeval scene. The lake and the river are so peaceful and pristine that you feel as if you’ve stepped into the pages of National Geographic. And then there’s the bioluminescence — swimming in waters that glow and sparkle with every movement is nothing short of magical.
But what truly elevates the whole experience is Alexis. He is not just a guide — he is a passionate storyteller and a deeply knowledgeable naturalist. Certified and constantly expanding his expertise, Alexis shares real facts about the nature and history of the area with contagious enthusiasm. He doesn’t rely on myths or embellishments; instead, he brings the landscape to life with science, history, and insight — all delivered in a way that is engaging and easy to follow.
What I appreciated most was his sensitivity to the moment. He knew exactly when to step back and let us simply be — to savour the silence of the sunset, the stillness of the water, or the wonder of swimming in glowing light — and when to step in and enrich the experience with fascinating stories. Even small gestures, like skilfully speeding the boat to get a closer look at birds or preparing a cosy campfire with marshmallows, showed how much care and thought he puts into every detail.
This isn’t just a tour — it’s an extraordinary, once-in-a-lifetime experience crafted with knowledge, passion, and heart. And Alexis is the reason it becomes something truly special."

"We drove to the lagoon with our motorbike (not advisable if you get scared to drive at night, it’s around 30 minutes from the city center to the lagoon) and stopped at the side of the road when we saw the signs for the tours.
We didn’t want to spend 600 pesos on a tour, so we decided to go there and try it.
They asked us for 150 pesos!! AMAZING!!
Tour guides are friendly, and the boat ride is unforgettable. You ride for 15 minutes into the middle of the lagoon and then you jump in the water in the dark!
When you move the water lights up due to the plankton. We recommend everyone to do this, we had so much fun!"

Driving at night can be challenging, especially if you're unfamiliar with the roads. Some travelers have reported it's about a 30-minute drive from Puerto Escondido. If you're not comfortable driving in the dark, consider a guided tour.
Public transportation options directly to the lagoon might be limited. It's generally easier to arrange a taxi or join a tour that includes transport from Puerto Escondido.
Yes, many tour operators offer pick-up services from hotels in Puerto Escondido, making it a convenient option for experiencing the bioluminescence.
You can book tours in advance online, through your accommodation, or by looking for local operators with signs along the road near the lagoon for potentially more affordable options.
🎫 🎫 Tickets & Entry
Tour prices can vary significantly. While some organized tours might cost around 600 pesos, travelers have found local operators offering similar experiences for as little as 150 pesos. It's worth exploring options upon arrival.
Booking in advance is recommended, especially during peak season. However, you can often find local guides offering tours on-site, particularly if you arrive a bit earlier.
Tours typically start after sunset, around 7 or 8 PM, and continue into the night. It's best to confirm the exact start time with your chosen tour operator.
The primary cost is for the guided tour, which includes the boat ride and the experience of seeing the bioluminescence. There isn't typically a separate entrance fee for the lagoon itself.
While the main attraction is the nighttime bioluminescence, the lagoon and its surrounding landscape are also beautiful during the day. Some tours might offer daytime excursions focusing on birdwatching or the natural scenery.
🎫 🌟 Onsite Experience
Bioluminescence is the production and emission of light by a living organism. In Manialtepec Lagoon, it's caused by microscopic plankton that glow when disturbed by movement in the water, creating a magical, sparkling effect.
Tours usually involve a boat ride into the lagoon, followed by an opportunity to swim or kayak in the glowing waters. Guides will explain the phenomenon and point out wildlife.
Yes, swimming in the lagoon is generally safe and is the best way to experience the bioluminescence. Guides ensure the safety of the area, though some travelers mention initial concerns about crocodiles, which are usually not an issue during tours.
The best season for bioluminescence in Manialtepec Lagoon is typically from June to December, when the water conditions are optimal.
While you might still see some glow, the bioluminescence is significantly less visible during a full moon because the moonlight can overpower the faint glow of the plankton. Moonless nights are ideal.
📸 📸 Photography
Capturing the bioluminescence on camera can be challenging due to the low light conditions. Long exposure settings on a good camera might yield results, but it's often difficult with phone cameras.
If you're serious about photography, use a tripod, a wide aperture (low f-number), a high ISO, and a long shutter speed. Experimentation is key, and many find it best to just enjoy the moment.
Most smartphone cameras struggle to capture the subtle glow of bioluminescence. While some newer phones with advanced night modes might get a faint hint, it's unlikely to match the visual experience.
The best 'viewpoint' is actually in the water! The magic happens when you move, so the most impactful 'photos' are often the memories you create.
If you plan on swimming and want to try capturing photos or videos in the water, a waterproof camera or a waterproof case for your phone is highly recommended.

Consider driving yourself if you're comfortable with night driving to save on transportation costs. Alternatively, look for shared taxi options or inquire about group rates. The key is to be flexible and explore options on the ground rather than committing to the first tour you see.

In-depth insights and expert knowledge
The Magic of Bioluminescence
Several factors influence the intensity of the bioluminescence. The best time to witness this phenomenon is during the darker months, typically from June to December, when rainfall can increase nutrient levels in the lagoon, supporting a larger plankton population. Crucially, moonless nights offer the most vibrant displays, as the ambient moonlight can significantly diminish the visibility of the plankton's glow. Travelers often report that the experience is far more profound when the sky is dark and clear.
While the bioluminescence is the main draw, the Laguna de Manialtepec itself is a beautiful and largely untouched natural landscape. Surrounded by mangroves and lush vegetation, the lagoon offers a serene escape. Some tours also highlight the diverse wildlife, including various bird species, that inhabit the area. It's a place where nature's wonders are on full display, from the vibrant ecosystem during the day to the magical glow at night.
Experiencing Manialtepec: Tours and Tips
When choosing a tour, travelers have discovered that local operators can offer significant savings. While some organized tours might be more expensive, looking for signs and inquiring with guides directly along the road near the lagoon can lead to more budget-friendly options, sometimes as low as 150 pesos compared to 600 pesos. This makes the experience accessible to a wider range of travelers. It's also advisable to confirm the start time of the tour, as some have reported delays, with experiences sometimes beginning later than initially stated.
Practical advice from visitors includes bringing a towel and a change of clothes, as you will likely get wet. If you plan on driving yourself, be aware that the journey from Puerto Escondido can be about 30 minutes and may involve driving at night, which requires caution. For those seeking an even more immersive experience, kayaking is another option offered by some operators, allowing for a more intimate encounter with the glowing waters.
