The natural world is full of wonders, but is there anything more mesmerizing than swimming at night in a sea glowing with bioluminescence? Or spying on flickering fireflies in woodland as they dance through the air? 

Bioluminescence is when living organisms – animals, plants and fungi – produce and emit light, and Mother Nature adds this touch of whimsy to the environment in many different forms and in many different places. You just have to know where to look.

You could be closer to some of these sparklers than you realize. Here are our favorite places to go for the glow.

The still waters of Garrison and Westcott Bays, just off San Juan Island, are the setting for a spectacular light show in Washington State. These nutrient-rich bodies of water create an environment that fosters bioluminescent microorganisms – a natural attraction that travelers flock to once the sun has set. 

San Juan Island Outfitters offers tours timed with the new moon in summer for peak visibility. 

Post-glow activities: Grab a pint at San Juan Brewing Company. The next day, check out the wildlife and the lighthouse in nearby Lime Kiln Point State Park.

When most people think of Cambodia, Angkor Wat springs to mind. In the southern part of the country near Sihanoukville is another epic experience: Koh Rong, an island where you can snorkel in sparkling bioluminescent waters. Book a boat tour that will take you out on the water, and be sure to swirl your hand through the water to see the plankton at their brightest.

Stay at Long Set Resort, which gives guests a shoreline view of the twinkling colors lighting up the sea. 

Post-glow activities: Mountain bike through the forest or take an ocean dive to view marine wildlife.

In Mexico, Oaxaca’s Manialtepec Lagoon is known for its bioluminescent light show. While you can stay in the boat, jumping in is encouraged. In ancient times, the locals believed in the youthful magic of bathing in the phosphorescent lagoon. Just be sure to time your nighttime dip with the new moon, as light makes it challenging to see the bioluminescence.

Stay in Puerto Escondido and book a tour from there — they are offered most nights. The lagoon is less than 30 minutes from Puerto Escondido.

Post-glow activities: Bird-watching is a must in Manialtepec Lagoon. Parrots, pelicans, falcons, ospreys, herons, kingfishers and hawks call the area home.
