What should I wear?
Dress in warm layers. It cools off fast once the sun goes down, even in summer. A fleece or light puffer, pants over swimwear, and something that blocks wind are all good calls. We provide wind-blocking splash tops which is why we ask for your size. Bring a full change of dry clothes for after, plus closed-toe shoes you don’t mind getting wet, since you’ll be wading in at launch.
What should I expect on the tour?
You’ll meet your guide before sunset for a full safety orientation, then paddle out onto the bay as it gets dark. Each kayak will have its own lights! Once you’re away from shore lights, your guide will show you how to experience the glow: dip a paddle or a hand in the water and it lights up around you. The pace is easy and mostly quiet, three hours total including the orientation.
What happens if the weather doesn't cooperate?
If wind, rain, or unsafe conditions mean we can’t paddle safely, we’ll reach out ahead of time to get you rebooked on another night or offer a full refund.
How does parking work?
Parking is at Nick’s Cove and Miller Boat Launch on Highway 1, about three miles north of Marshall. Your guides will be there to greet you and help you get parked.
What else is there to do before the tour?
Since tours meet in the early evening, plenty of guests make a day of it. Nick’s Cove has a restaurant on site if you want an early dinner before you paddle, plus lawn games like bocce and cornhole. A few minutes down the road, West Marin’s cheese and wine scene is hard to beat: Point Reyes Farmstead Cheese Co., The Marshall Store, Marin French Cheese Company, Bohème Wines, and Heidrun Meadery are all nearby, along with the shops and bakeries in Point Reyes Station.
What causes bioluminescence?
The glow comes from dinoflagellates, tiny single-celled organisms in the bay’s water. When they’re disturbed, by a paddle stroke, a fish, or your hand, they emit a quick flash of blue-green light. It’s a defense response, which is why movement is what makes the water light up.
Am I guaranteed to see it?
Bioluminescence is a natural phenomenon tied to algae blooms in the bay, so we can’t guarantee it every night. Our guides pick nights and routes based on conditions to give you the best possible chance, and most nights deliver a great show.
What's the best time to see it?
The glow is visible year-round, but it’s typically brightest from late summer into fall, roughly August through November, and on the darkest nights around the new moon. We schedule tours around the moon calendar for exactly this reason.
