This rare natural phenomenon is only visible in a handful of places around the world—and the San Juan Islands are one of the best.

HOW DO I CHOOSE A DATE FOR MY BIOLUMINESCENCE KAYAK TRIP IN FRIDAY HARBOR?

Bioluminescence and the lunar cycle have a strong relationship. A bright full moon will make the glowing organisms seem dimmer. Oppositely, a dark new moon will allow the full glory of bioluminescent organisms to shine! The “in-between” phases of the lunar cycle offer moderate displays. To increase your chances of seeing a good bioluminescence display on your kayak trip with Sea Quest, use the lunar calendar on this page and select a date with a darker moon. If you want to see a partial moon, the best time to do so is during the third quarter phase. This is when the moon is waning and rises later at night. The first quarter moon rises well before the sun sets, so it is not as visible. For more info, see our page on how to interpret a lunar calendar to maximize your chances kayaking in bioluminescence!

Trip Fee: $179 per person. On rare dates, the fee is $199+ due to limited resources, and this will be noted in the online reservation system.

Meeting Place: Friday Harbor, San Juan Island. Look for our van and kayak trailer in the traffic circle adjacent to the Friday Harbor Ferry Terminal.

Meeting Time: Bioluminescence kayak trips usually begin at dusk. Note that the trip start times in our reservation system vary with seasonal daylight hours. Our online reservation system will indicate the exact meeting time if you enter a specific date. If the times don’t work for you, we may be able to change them to meet your needs so feel free to ask!

Itinerary: Our shuttle van takes you to the launch beach. The drive takes between 5 to 25 minutes. We provide a one hour kayak lesson on the beach. This lesson familiarizes everyone with the basic skills before we launch the sea kayaks in the dark. We then explore for about 1 – 1½ hours, covering 1 to 2 miles during the kayak adventure. We will paddle at a leisurely pace in search of good areas. If we find a rich spot we will float there to soak in the experience and look for the glowing outlines of fish and seals. Remember to bring a headlamp or flashlight but turn it off to enjoy the bioluminescence!

Finish Time & Place: Friday Harbor Ferry Terminal. 3 hours after we pick you up.

Total Time: Approximately 3 hours from meeting your guides to finish. Be aware that our weather, winds or currents can occasionally delay us!

WHAT IS BIOLUMINESCENCE?

Bioluminescence in the sea is a fascinating phenomenon primarily produced by plankton, which are tiny organisms that drift with currents. Among these plankton, dinoflagellates are particularly notable. These microscopic organisms harness the sun’s energy during the day and produce light at night when disturbed by movement in the water. This light is often seen as glowing sparkles in response to disruptions caused by fish, seals, kayaks, or even the swells of the ocean.
 

Other creatures that contribute to this glowing spectacle include pulsating jellyfish, clusters of salps (gelatinous organisms), and even masses of mating marine worms. Each of these organisms uses bioluminescence for various purposes, such as communication, attracting prey, or deterring predators, making the sea at night a glowing and magical place.

WHY DOES BIOLUMINESCENCE EXIST?

The “Enemy of My Enemy is My Friend” hypothesis offers an intriguing explanation for bioluminescence in the sea. According to this theory, some organisms use their ability to glow as a defense mechanism against predators. When small predators, such as zooplankton, approach, the bioluminescent organisms release a burst of light. This glow may distract the predator or attract a larger predator that will target the zooplankton instead, diverting attention away from the glowing organism and giving it a chance to escape.

 

In addition to this defensive use, bioluminescence serves other purposes as well. Some creatures, like jellyfish, use their glow to attract prey, similar to how moths are drawn to a candle’s light. This strategy helps them lure in smaller organisms, such as phytoplankton, to feast upon. Meanwhile, creatures like nereid worms utilize their bioluminescence to attract mates, turning their glow into a sort of “sexy” beacon, signaling potential partners in the vast ocean depths. Overall, bioluminescence is a versatile tool that serves various functions in the underwater world, from self-defense and hunting to reproduction.

IS BIOLUMINESCENCE THE SAME THING AS PHOSPHORESCENCE?

Bioluminescence is a strictly biological phenomenon, where living organisms produce light through chemical reactions involving the enzyme luciferase and the molecule luciferin, without generating heat. In contrast, phosphorescence is a process in non-living materials, where light is emitted after a substance absorbs energy and re-emits it over time. The confusion between the two terms arose during World War II, when soldiers saw light in the sea that resembled the color of their phosphor tracer bullets. Not understanding the biological basis of the glow, they mistakenly called it “phosphorescence,” and the incorrect term persisted for decades.
