Bioluminescence San Juan Kayaking Tours

Bioluminescent Kayaking San Juan Island

Explore the Night with Discovery

Price: $145 M-Thr / Person
Weekend Price: $160 F-Sun / Person

I did nighttime bioluminescence kayaking 3 nights in a row in July. And Discovery Sea Kayak was the winner! Of course, when the bioluminescence is out, it’s magical, regardless of who you are with. Although this company truly understands how to craft an experience – above and beyond the kayaking itself. (Review 2023)

Over 15 years ago we started leading guests during the nighttime to witness the beauty of bioluminescence. In the heart of the San Juan Islands, our home base, we created the first dedicated Bioluminescence Kayak Tour in the islands. Over these 15 years, we have perfected the process and developed safety protocols to ensure everyone feels comfortable exploring on this unique nocturnal adventure. 

All of our guides have undergone rigorous kayak training, conducted by our in-house American Canoe Association kayak instructor. Further, guides have a Washington State Kayak Guide License. We are professionally prepared, meticulously organized, and extremely enthusiastic to have you along on our Bioluminescence Kayak Tour. 

Dates are limited each month of the summer to ensure we paddle at times when the moon phase is either small or absent. This creates the darkest nights where the bioluminescence will sparkle with its anticipated intensity. The dates are selected to provide you with the best experience possible. 

Group Sizes and Departures

We have two departures each night. We stagger our departures to maintain our small groups and custom feel. Both departures operate in the same location and will have the same experience. The maximum group size is 10 guests with 2 guides. Small groups give guests full access to guides to ask questions and learn all the amazing information about bioluminescence.

Bioluminescence San Juan Kayaking Tours Testimonial

My partner and I had an amazing time from start to finish. It was her first time seeing bioluminescence and was such a great experience. Our tour guides were professional, knowledgeable, and very personable.

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.
