Cocoa Beach: Bioluminescent Kayak Tour Clear Bottom & Glowing Water

Paddling over glowing plankton that light up when you move through them

You paddle a clear-bottom kayak or paddleboard at night on the Indian River, watching glowing plankton light up beneath you as you move. The tour includes your kayak, paddle, lifejacket and dry bag. Bioluminescence is seasonal — dinoflagellates glow June through October, comb jellies October through March — so book for the season that matches what you want to see. Call after booking to reserve your gear type and confirm your arrival time.

The Experience

"You'll see it the moment your paddle hits the water," the guide told us before we pushed off. That's the thing about bioluminescence — it's not something you read about and then forget. The Indian River near Merritt Island stays calm at night, and the clear-bottom kayaks let you watch the underwater show without getting wet. Depending on the season, you're either chasing dinoflagellates (June through October, when the water glows bright blue) or comb jellies (October through March, when they pulse like tiny jellyfish made of light). The timing matters because bioluminescence shifts with the plankton, so what you see changes every few months.

The kayaks themselves are the whole point — they're hybrid sit-on-tops with transparent panels built into the hull, so you're looking straight down at the water without leaving your seat. Single kayaks hold up to 350 pounds, tandems work too, and paddleboards (also clear-bottom) max out at 280 pounds. Lifejackets come in sizes from 30 pounds up, and the company throws in dry bags so your phone doesn't end up in the river. No shoes allowed in the clear-bottom kayaks — the material can't handle them — but that's a small trade for seeing what's moving underneath you in real time. After you book, call the office to reserve your exact gear and get the waiver links and directions; if you don't call ahead, it's first-come-first-served when you arrive, which means you might not get your preferred kayak type.

The tour runs year-round, but the bioluminescent season peaks in summer and winter depending on which organism is active. June through October brings the dinoflagellates, which create that electric-blue glow the moment you disturb the water. October through March switches to comb jellies, which look like tiny glowing ghosts drifting through the darkness. Either way, you're paddling on a living system, not a fixed show — some nights the glow is brighter than others, and that's just how it works. The Indian River is protected and shallow, so the pace is easy and the water stays calm. Bring a headlamp or let your eyes adjust to the dark; the bioluminescence does most of the work.

Top questions

What's the difference between dinoflagellates and comb jellies?

Dinoflagellates (June–October) create a bright blue glow when the water is disturbed. Comb jellies (October–March) look like tiny glowing jellyfish drifting through the water. Both are bioluminescent, but they appear in different seasons.

Do I need experience to paddle a clear-bottom kayak?

No. The tour is suitable for all fitness levels, and the Indian River is calm and shallow. The kayak is stable and the pace is easy.

What if I'm over the weight limit?

Single and tandem kayaks hold up to 350 pounds. Paddleboards max out at 280 pounds. Call the office after booking to confirm which gear works for you.

Can I bring my phone or camera?

Yes. Dry bags are included with your rental, so you can keep your phone and camera protected during the tour.

What should I wear?

Wear clothes you don't mind getting wet. No shoes are allowed in the clear-bottom kayaks because of the material. Bring a light jacket if it's cool, and consider a headlamp so you can see the bioluminescence better.

Is the tour accessible for people with mobility issues?

The tour area and surfaces are wheelchair accessible, and transportation options are wheelchair accessible. However, the tour is not recommended for travelers with spinal injuries or poor cardiovascular health.

Can children go on the tour?

Yes. Infants and small children can ride in a pram or stroller, and infants must sit on an adult's lap during paddling. Lifejackets are available for weights 30 pounds and up.

What happens if there's no bioluminescence on the night I go?

Bioluminescence is a natural phenomenon and brightness varies night to night. The tour operates year-round, but the best viewing is during peak seasons: June–October for dinoflagellates, October–March for comb jellies.
