Bioluminescent Bay Kayaking Tours in Puerto Rico

250 Reviews
After the sun goes down and the stars come out, the dark bays of Puerto Rico become illuminated by tiny bioluminescent plankton—one of the most spectacular sights in the Caribbean. Puerto Rico is home to some of the few remaining bioluminescent bays on the planet, and one of the best ways to enjoy the view of this natural phenomenon is from a kayak. See below for your options.

Fajardo's Laguna Grande
Located within Las Cabezas De San Juan nature reserve, mangrove-lined Laguna Grande sits on the northeastern coast of Puerto Rico, and its calm waters make paddling easy. As your kayak moves through the water, thousands of tiny pyrodiniums bahamenses organisms produce a blue-green light, creating an eerie glow beneath the night sky. A kayaking trip through this serene lagoon presents an excellent opportunity to learn more about this delicate ecosystem and the marine life that use it as a sanctuary.

Mosquito Bay on Vieques
The island of Vieques, situated off the coast of mainland Puerto Rico, has its own bioluminescent bay, known as Mosquito Bay. Of the bioluminescent bays in Puerto Rico, this is considered the brightest. While this bay isn’t as easily accessible as Laguna Grande, the blue-green glow produced by the dinoflagellates in these waters is a worthy reward for your efforts.
