The experience

You're picked up at your chosen spot and driven to Mosquito Bay, where the guide meets you at the water's edge. The transparent kayak is the whole point: you sit low enough to see straight through the hull into the water below, and when you paddle, every stroke disturbs the dinoflagellates and makes them glow. The guide paddles alongside, pointing out the biology behind the light and answering questions as you explore for about an hour.

The bay itself is the attraction: no stops, no landmarks to visit. The glow is brightest on moonless nights and when the water is calm, and the guide knows the conditions and the timing. After an hour on the water, you paddle back, get dried off, and the guide drives you back to where you started. The whole experience, door to door, takes roughly 100 minutes.

Life jackets and paddles come with the kayak. The tour suits any fitness level, and the guide speaks English, Spanish or Chinese depending on what you need.

Top questions

What languages is the tour guided in?

Live guide in English, Spanish and Chinese.

What happens if it rains?

It may be canceled due to bad weather. If that happens, you're offered another date or a refund. Free cancellation up to 24 h before the start.

What exactly is bioluminescence and why does Mosquito Bay glow?

Mosquito Bay is home to millions of dinoflagellates: single-celled organisms that produce light when disturbed. When you paddle or move through the water, you trigger that light, making the bay appear to glow. The guide explains the science as you paddle.

Can I kayak Mosquito Bay on a night with a full moon?

Yes, you can kayak any night, but the glow is harder to see when the moon is bright. Moonless or new-moon nights show the bioluminescence most clearly, so many paddlers book around those dates for the strongest effect.

How long do I actually spend paddling in the water?

You paddle for about an hour. The full experience, including pickup, the drive to the bay, and the return trip, takes roughly 100 minutes total.

What if I'm not a strong swimmer or have never kayaked before?

The tour is suitable for all fitness levels. You wear a life jacket the whole time, the kayak is stable and transparent (so you can see the bottom), and the guide stays with you throughout. No kayaking experience is required.

Do I need to bring anything, or is everything provided?

The kayak, paddle, and life jacket are all provided. Wear clothes you don't mind getting wet, and bring a towel if you have one. The guide can help with drying off after the paddle.
