We usually look up to see the stars, but how about if we look the other way around? Find a pitch black canvas adorned with twinkling blue lights, resembling a constellation. Those unusual yet astonishing lights come from a substance named bioluminescence. It is a natural light produced by animals and protozoans, including fireflies and glow worm. However, when we talk about bioluminescence, it often refers to a magical phenomenon of blue lights created by a collection of microorganisms. So, where to see bioluminescence? This blog will show you the best places to travel to if you want to see the breathtaking natural wonder.
Where to See Bioluminescence – Summary
- Maldives
- Mosquito Bay, Puerto Rico
- Isla Holbox, Mexico
- Luminous Lagoon, Jamaica
- Koh Rong, Cambodia
- San Diego, USA
- Space Coast, Florida, USA
- Jervis Bay, New South Wales, Australia
- Waitomo Glow Worm Caves, New Zealand
- Auckland, New Zealand
1. Maldives
The archipelago of the Maldives consists of dozens of small islands in the Indian Ocean. Two of them are bioluminescent water locations, which are Vaadhoo (Mudhdhoo) Island and Rangali. These two islands obtain ‘Sea of Stars’ as their nickname, reflecting the beautiful scene of bioluminescent waves once the sun goes down. Thanks to microorganism called dinoflagelletes emitting the lights, Vaadhoo and Rangali become some of the world’s most beautiful places to visit.
Among other destination, the beaches in Maldives offer the most ‘relaxing’ way to enjoy bioluminescence. The bioluminescent waves start appearing when the sun goes down. They crash to the beach and sometimes leave traces of blue light on the sand. Then, when to visit Maldives to see bioluminescence? Local guides recommended to visit in July-February for higher visibility of the blue lights.
2. Mosquito Bay, Puerto Rico
Mosquito Bay on the island of Vieques belongs to Puerto Rico and is one of the best places to experience bioluminescence, along with the Maldivian islands. Here the small organisms produce so much light that you could read a book on the beach! In Mosquito Bay, you can also go out by kayak and become part of this crazy carpet of lights. In the mangrove forests, which rise directly above the sea, the little animals find enough food to prepare for their nightly task.
Another place in Puerto Rico where you can observe the sea light is the Laguna Grande in the northeast of the main island. In the past, you had to go really deep into the lagoon to see the sea light on the beach. But in the last few years it has spread all over the lagoon so that when you kayak on the open water, you are surrounded by thousands of tiny spots of light. Especially the beginning is very magical because you don’t know when the spectacle starts. You should paddle out before sunset and then you have to wait, but keep a close eye on the water. And suddenly it looks like sparklers are burning and fizzing under the water until all the water is nothing but light.
3. Isla Holbox, Mexico
“Travel to Punta Cocos, just 1.2 miles from Isla Holbox city center, to see Mexico’s most vibrant bioluminescence scene. Although June and August are the best months to see them, the end of the year also gives a great chance to see them,” said TripLeader Ellis, a travel expert who hosts week-long trips all around the equator.
Our community notes that Isla Holbox is Mexico’s unmissable paradise. Powdery beaches, colorful street art, and laid-back island vibes – all the building blocks for a perfect tropical getaway. However, beyond the sunny skies, nighttime brings magic to the small island. The shallow shores light up with glowing plankton, turning the water into a natural starry sky beneath your feet. On calm summer nights, every step or paddle through the water sparks brilliant flashes of blue, making it feel like you’ve stepped into another world. Therefore, Isla Holbox is one of the best places to see bioluminescence that are great for both daytime and night
4. Luminous Lagoon, Jamaica
Located near Falmouth, Jamaica’s Luminous Lagoon is one of the brightest and most famous bioluminescent bays in the world. Here, millions of microorganisms called dinoflagellates produce an otherworldly blue glow whenever the water is disturbed. Night boat tours take visitors across the lagoon, where jumping in for a swim leaves glowing ripples around you. With its rare concentration of glowing plankton, the Luminous Lagoon is a once-in-a-lifetime spectacle.
5. Koh Rong, Cambodia
Travelers fly to Cambodia to see the legendary Angkor Wat and explore Siam Reap. But what if we told you that Cambodia houses one of the most stunning bioluminescent water locations? “The beautiful island of Koh Rong was once backpacker’s beloved before it gradually loses its beauty due to massive development. However, it’s still worth visiting for the magical bioluminescence scene that you should not miss,” said TripLeader Timo, a backpacker for Germany who has spent the past 3 years exploring Southeast Asia.
The island of Koh Rong in Cambodia is not only known for its white sandy beaches but also its shimmering waters at night. On moonless evenings, the ocean becomes alive with glowing plankton that illuminates every movement. Many travelers experience this by snorkeling or swimming after dark, surrounded by dazzling sparks of blue. It’s a hidden gem for those seeking a more adventurous and less commercialized bioluminescent encounter.
6. Space Coast, Florida, USA
When talking about the best places to see bioluminescence, we won’t leave Florida out. It is the United States‘ hotspot for bioluminescence, particularly during the summer months from July to September. Then, some of the best places to see bioluminescence in Florida are Indian River Lagoon and Mosquito Lagoon. You can kayak through glowing waters where every paddle stroke leaves behind trails of shimmering light. Both plankton and comb jellies contribute to the glow, making the experience unique depending on the season. Aside from its simply magical scene, Florida offers easy access for travelers who want to come and see.
7. San Diego, USA
You can also observe bioluminescence in San Diego, the southernmost city of the state of California in the USA. But be careful: the sea glow occurs here only every 5 years and that for just a week to a month! Between the cities of La Jolla and Encinitas, the sea glows red during the day and light blue after sunset. The stronger the sun shines during the day, the more the animals glow at night.
Because of the red coloring during the day, the phenomenon is also called “Red Tide” here and surfers use the different lights for breathtaking stunts and videos. Unfortunately, it is difficult to predict when the next sea light will be in San Diego because the so-called algae bloom causes the phenomenon and it is unpredictable.
8. Jervis Bay, New South Wales, Australia
Australia stuns travelers with its abundance of living species. It is not a surprise that Australia houses one of the world’s bioluminescence-seeing spots. Jervis Bay in New South Wales gains lots of love due to its pearly beach, gorgeous gradients of blue, and magnificent marine life. Besides that, the bay has become home to light-producing planktons. They tint the waves with otherworldly blue lights on warm summer days.
Besides Jervis Bay, there are several places in Australia where you can see bioluminescence. Some of them include Tasmania, specifically Hobart waterfront. So, if you need a reason to travel to Australia, this breathtaking phenomenon can be it!
9. Waitomo Glowworm Caves, New Zealand
Shift from the ocean waves to the land terrains, in which another type of bioluminescent creature awaits. Waitomo Glowworm Caves has become home to an endemic glowworm species called Arachnocampa luminosa. The surreal turquoise-colored light these worms produced create a scene that might remind you of the Avatar movie. Entering Waitomo Caves makes you feel like you are entering the fictional Pandora realm, which is a bucket list-worthy activity.
Besides the glowworm, Waitomo Caves will take your breath away with its facade. The cave has stood for 30 million years, adorned with marine fossils and millenia-years-old stones. You can take a guided tour to explore the cave while learning about its history.
10. Auckland, New Zealand
Near Auckland, New Zealand, the Waitematā Harbour and surrounding bays sometimes come alive with bioluminescent plankton. The phenomenon is particularly visible in the warmer months when conditions are just right. Kayak tours offer a front-row seat to the spectacle, as each dip of the paddle stirs glowing trails beneath the water. With Auckland’s city skyline as a backdrop, the contrast of natural and urban beauty makes it a truly memorable experience.
Bioluminescence is an ethereal natural phenomenon you should see before you die. So, put these places to see bioluminescence into your bucket list!
