Bioluminescence Tour

We are NOT located in San Juan Puerto Rico. We are in Washington State USA

Being on the water at night can be a special experience. The allure of the darkness and the still calm of the night really creates a setting that is hard to beat. The San Juan Islands have good tidal exchanges that develop highly nutrient rich bodies of water, creating an environment with a wide diversity of microorganisms. Some of which are bioluminescent. Bioluminescence is the emission of light by a living organism. In the San Juan Islands the organism most commonly emit a nice green burst of light. With the disturbance the kayaks and paddles make as we move across the water’s surface, these organisms give off a green sparkle of light. One of the main sources of bioluminescence in the San Juan’s is a dinoflagellate (a flagellated protist), Noctiluca. Noctiluca is a non-parasitic and non-toxic marine dinoflagellate common to the waters here. Some of the Jellies also emit light as well.

Come join us for a night of fun and one of nature’s most amazing light shows on our Bioluminescence Tour.

Kids on Bioluminescence Kayak Tours

We have set the age limit at 12 years of age and up for this tour for various reasons. With our experience kids younger than 12 years age 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 year of age, please contact us for information on a custom kayak tour.
