A bioluminescent bays (biobay) is a body of water that contains millions of micro-organisms, called dinoflagellates, that glow in the dark for a second when agitated. It is a rare, natural wonder that you can easily experience while visiting Puerto Rico. An adventure not to be missed! There are three biobays in Puerto Rico. One in the SouthWest (La Parguera), one on Vieques (Mosquito Bay), and the one in Fajardo (La Laguna Grande). Mosquito Bay is the brightest, and La Parguera is the least bright.

All the tours start off near the boat ramp, and then you kayak across the boat marina to a thin channel that leads to the lagoon. You have to go single file to avoid hitting each other and the sides of the channel. The mangrove trees make a canopy over your head, which is low in some spots. But as you get closer to the lagoon, you will notice little sparkles as you dip your paddles into the water. All of the kayak operators use sit-upon ocean kayaks, which means that your butt will get wet - wear a bathing suit or shorts that you don't mind getting wet. Also, getting in and out of the kayak requires you to walk in the water (usually no more than mid-calf deep), so wear water shoes or go bare foot. Bring a towel or something dry, so that when you get back to shore, you can dry yourself.

Expected cost of the biobay tour is about $70 and we leave at 6 pm on December 14 and on December 16. The attendees can pay cash on the day of the tour. We will go from San Juan to Fajardo, kayak in the biobay, then come back to San Juan. The trip takes about 4 hours from start to finish.
