Napa Valley Paddle’s Bioluminescent kayak touring company offers nature’s most illuminating light show in the waters of Tomales Bay on the darkest nights of July, August, September, and October, 2022. Bioluminescence is mother nature at its spectacular best. It is the emission of light by microorganisms undersea called marine dinoflagellate or plankton. Movements from a swimming fish, the stroke of a paddle to displaced water from the hull of your kayak can excite the organisms causing a shimmering burst of fluorescent green-blue light. With hundreds of marine dinoflagellates assembled in the bay, the collective effect can be magical.
Napa Valley Paddle’s blue water kayaking starts just before nightfall so that you can enjoy the rich colors of the sun setting on the horizon. As the evening fades into darkness, the sky is lit by stars above, followed by traces of bioluminescence glowing as its spills from your kayak paddle.
We’ve chosen the best dates for July, August, September, and October based on the moon’s position to ensure the darkest nights. Our guided tour will take you through areas where your kayak paddle creates long stretches of glowing bioluminescent for the longest time.
