Bioluminescent Bay

Vieques “bio-bay” is said to be the brightest  in the world.  You will kayak or boat to the center of Mosquito bay and see pretty blue sparkling water.  Some say it is the 8th wonder of the world.  Some people travel to Vieques for only one night just to have this magical experience. Don’t forget we also have some of the best beaches in the Caribbean.

Bio-Bay Tours

This is a list of some companies operating government-endorsed tours. Tours are in kayaks except for Island Adventures.  Most also offer snorkeling trips. Reserving a few days in advance is advisable, but not necessary.

Other tours to the BioBay may be found in this online directory.

Most of the tours to the bio-bay are about $50.00 per person (as of January, 2015). Rates do vary.   There is only one tour by electric boat.  Most people find handling the kayak easy – they do accept children on the kayak tours.   You can schedule your tour after you arrive in Vieques.  The exception is Christmas time, school vacation weeks, Easter, etc., when you may want to book at least a couple of days in advance.   Of course, there is nothing wrong with making your reservation a week or two in advance. The tours leave about 6:30 PM and sometimes there is a late tour at 9:00 or 10:00 PM depending on the demand.

The brilliance of the bio-bay is more intense without a moon in the sky. But most any night, you will still have a wonderful experience. Even two nights after the full moon it is great time because the moon rises late in the night.  Avoid going to the Bay 4-5 days before the full moon, the night of the full moon and the day after the full moon. In this calendar,  the white circles indicate the full moon:  2016 Moon Watch Calendar

When you go to the bio-bay, avoid using sunscreens or insect repellent which may pollute the bay.  Leave valuables and your camera in your guest house except the money you need to pay for the tour.   Unless you have a special camera, you cannot capture the glow on a camera.
