Laguna Grande – The Bio Bay Closest to San Juan
This is the island’s most accessible bio bay and Fajardo’s crown jewel. From the marina, you’ll paddle through mangrove channels alive with nighttime sounds, then glide into a lagoon that glows with every stroke of your paddle. Pair it with fresh seafood in town before or after your tour, or do a combo tour starting with a trek through El Yunque, just minutes away.
Guided tours lead you through mangrove channels and out into the glowing lagoon on a peaceful two-hour kayak trip. Local operators keep groups small and share stories about the bay’s ecosystem, history, and the science behind its light.
Tours book up fast, especially around new moon phases, so it’s worth reserving early to secure your spot.
