Bioluminescence Kayak Tour

The Bioluminescence Kayak Tours offer guests the opportunity to experience one of natures amazing light shows.

The San Juan Islands of Washington State have good tidal exchanges that yield highly nutrient rich bodies of water, creating an environment with a wide diversity of microorganisms. Some of which are bioluminescent, create their own light.

Bioluminescence is the emission of light by a living organism. In the San 417262_436104519765422_2117595000_nJuan Islands the organism most commonly emit a nice green burst of light. When a large amount of bioluminescent organisms collect 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 though areas where the disturbance of paddles and kayak 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.

The main sources of bioluminescence in the San Juan’s is a dinoflagellate (a flagellated protist), Noctiluca. Noctiluca is a marine dinoflagellate common to our waters.

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.
