“Honestly one of the most magical experiences of my life. We went on a moonless night and the water glowed blue every time we moved. Our guide was really knowledgeable about the plankton and gave everyone time to swim. Bring a swimsuit under your clothes — you'll want to get in the water.”

Good to Know
Moon phases affect the intensity;
the darkest nights (new moon) produce the most vivid bioluminescence. We always choose the lagoon with the best conditions for your date.
The water is warm and safe for swimming;
no prior swimming experience is required — life jackets are provided and your guide is always with you in the water.
Photography is welcome;
to capture the bioluminescence, use a camera with good low-light capabilities or a smartphone with night mode. Keep in mind that capturing bioluminescence can be challenging — but the memories will last a lifetime.
No sunscreen in the lagoon;
chemical products harm the bioluminescent plankton. Avoid applying sunscreen, lotions, or insect repellent before getting in the water. You can reapply after.
About four and a half hours total;
pickup at 5:30 PM, back at your hotel by approximately 10:00 PM. Transfer time depends on which lagoon we visit: 20 minutes to Manialtepec or 1 hour 15 minutes to Chacahua.

What travelers are saying
“Expérience irréelle. La lagune s'illumine de bleu à chaque mouvement, on a l'impression d'être dans un film de science-fiction. Nuit sans lune = meilleur effet. Le guide nous a emmenés au meilleur endroit et on a pu se baigner. À faire absolument.”
“I didn't think it would be that impressive but wow — when you move your hand in the water the entire surface lights up in neon blue. It's like swimming in stars. Our guide Manuel was fantastic, explained the science, and made sure everyone had a turn.”
“Die Manialtepec-Lagune leuchtet wirklich blau sobald man das Wasser bewegt. Wir sind an einem mondlosen Abend gefahren und es war magisch. Vergesst eure Kamera, die Handys können das nicht einfangen — einfach genießen.”
“Such a unique thing to do. The boat ride to the lagoon at dusk was already beautiful, then once the sun was fully down the real show started. Swimming with the glowing water all around you is something you have to experience to believe.”
