Bioluminescence San Juan Kayaking Tours

Bioluminescence Kayaking San Juan Islands

San Juan Islands Original Night Kayak Tour

Our Bioluminescence Kayak Tour is often imitated but never recreated. Leading the way we created the San Juan Island Bioluminescence Kayak Tour 7 years ago. When you read about bioluminescence paddling on San Juan Island, you are reading about Discovery Sea Kayaks. We have the most experience on the water at night, setting the standard for quality and safety.

Join the Bioluminescence Kayak Tour on San Juan Island and experience the natural lights from the depths of the ocean.

The San Juan Islands of Washington State have significant tidal exchanges that create swift currents and ocean upwellings. These upwellings yield highly nutrient rich bodies of water, creating an environment with a wide diversity of microorganisms. Some of these microorganisms are bioluminescent, creating their own light.

We launch just before sunset to take advantage of the last bit of daylight and enjoy the rich colors as the sun drops below the horizon.

Bioluminescence is the emission of light by a living organism. In the San Juan Islands this organism is a marine dinoflagellate (a flagellated protist), called Noctiluca. When disturbed, noctiluca emits a sparkling green burst of light. When many bioluminescent organisms congregate in bays, the collective effect can be very dramatic.

We launch just before sunset to take advantage of the last bit of daylight and enjoy the rich colors as the sun drops below the horizon. As twilight fades to darkness, green sparkles become noticeable throughout the water. Traveling close together we will pass through areas where the disturbance of paddles and kayaks create long streaks of bright green on the surface of the water. Floating in shallow flats, darting fish create a light show beneath the kayaks.

Bioluminescence San Juan Kayaking Tours Testimonial

Magical! A one of a kind experience! We did the bioluminescence kayak tour and we LOVED it! It was incredible to kayak at night and see the bioluminescent plankton. It was magical to see the water turn blue with motion.

Route & Itinerary

Each departure time will be slightly different as it will be based on sunset and moon rise. You should eat dinner prior to check-in as our arrival back to town will be past open hours for in-town establishments.

Please reference our online reservation calendar for departure times and real-time availability.

Kids on Bioluminescence Kayak Tours

Children must be at least 12 years of age to join this tour. With our experience kids younger than 12 usually fall asleep well before we begin to see the bioluminescence and often become unhappy about being in the boats. If you would like to reserve a Bioluminescence Kayak Tour with kids less than 12 years of age, please contact us for information about setting up a custom kayak tour.

Wildlife & Weather


The focus of the Bioluminescence Kayak Tour is one of the area’s tiniest visible organisms, noctiluca. Before these sparkling creatures are visible we may also encounter a variety of other wildlife:

  • Porpoise: Harbor and Dalls porpoise are encountered year round.
  • Harbor Seals, California Sea Lions, and Stellar Sea Lions: Fairly Common in these areas.
  • River Otters: More elusive but seen any time of year. Most sightings are early morning or late afternoon.
  • Bald Eagles: San Juan host a healthy population of Bald Eagles with many nesting sites.
  • Great Blue Herons: Commonly encountered along the shorelines.

Every evening is unique and we can encounter other species of birds and marine life not listed above.


Evening and Night Time: Summer weather on San Juan Island can shift drastically from daytime to nighttime. While early evening temperatures may stay in the 60’s F, once the sun sets temperatures can drop quickly into the low 50’s F. While evenings are typically calm, we do occasionally experience breezy conditions.
