11 Bioluminescent Bays – Kayaking Through Glowing Waters 2024

Bioluminescence, the natural phenomenon where living organisms emit light, transforms certain bays and lagoons into ethereal, glowing waters under the cover of night. This magical display, caused by microorganisms such as dinoflagellates, offers a unique experience to those who venture into these luminous waters. Kayaking through bioluminescent bays allows for an intimate encounter with this natural wonder, where every paddle stroke ignites a burst of underwater stars. From the renowned Mosquito Bay in Puerto Rico to the hidden gems in Australia, this guide explores eleven destinations to embark on a kayaking journey through glowing waters.

1. Mosquito Bay, Vieques, Puerto Rico

The absence of light pollution on Vieques enhances the visibility of the bioluminescence, making it a must-visit destination for nature enthusiasts.

Insider’s Tip

Visit on a new moon night when the skies are darkest to witness the most intense bioluminescence. Avoid using flashlights or taking photos with flash, as this can diminish your night vision and the overall experience.
