What is a Bioluminescent Bays?
It is a bay that contains millions of micro-organisms (dinoflagellates) that when agitated glow. The glow of the Bio-bay is best seen when the night sky is moonless or there is very little moonlight and most tour operators will not offer tours when the moon is not favorable. How to Visit the Fajardo Bio-Bay Currently swimming is NOT ALLOWED at the Fajardo Bio-Bay (if this is important to you, then you need to visit the Vieques Bio-Bay) and up until recently the main option for touring the Bio-Bay was by Kayak. There is now a second option which allows you to visit the Fajardo Bio-Bay and remain on land; the La Cabezas Reserve now offers walking tours of the Bio-Bay. So if you are unsure about a kayak trip, this is an option worth checking out. For the kayak tours, all tour operators meet at the Las Croabas boat ramp and most offer 2 trips during the evening. Times of these tours will depend on the time of year, but the first tour usually starts around 6 to 6:30pm, lasting about 2 hours
