The night arrives soft and low over Vieques, and the water at Mosquito Bay answers with a quiet electric blue. Paddles slip through ink-dark channels and each stroke unspools a ribbon of light, the tiny organisms lighting up as if the lagoon itself is breathing.

History
Vieques was used as a U.S. Navy training range for decades until the early 2000s; the island’s recovery and community advocacy shaped today’s tourism and conservation approach.
Conservation
The bay’s bioluminescence is sensitive to light, pollution and boat traffic — operators limit group size, forbid flashes, and emphasize 'leave no trace' practices to preserve the ecosystem.
Reserve your spot on the Bioluminescent Bay Kayak Trip from Vieques today and enjoy a trusted, highly rated experience designed to help you make the most of your adventure.
Book an overnight stay
Ferries and flights don’t align with late returns — plan to sleep on Vieques the night of your tour.
No bright lights
Flash photography and headlamps disrupt bioluminescence — use only red or dim lights when permitted by your guide.
Hydrate before launch
Bring a full water bottle; guides provide a short van transfer but water on the bay is limited.
Protect your gear
Use a small dry bag or waterproof case for phones and cameras — splash and humidity are constant.
Small dry bag
Keeps phone, wallet and light layers dry during the transfer and on the kayak.
Reusable water bottle
Hydrate before and after the night paddle — guides typically won’t have drinking water on the bay.
Light windlayer
Even in tropical climates, evenings on the water can feel cool with breeze and spray.

Waterproof camera or phone case
