Paddle through Fajardo’s mangroves to Laguna Grande, where microscopic plankton glow blue at your touch on this guided night kayak tour.

“We could not see any bio illumination. Would not have booked the excursion had I known it wasn’t going to be visible. Paid $400 for a night kayak tour for 4. Way too many people trying to fight their way through the mangrove. Not sure why there were boats traveling at the same time, seemed dangerous for the people trying to get out of their way”

5.Puerto Rico Sunset Magic: Bio Bay Kayaking Tour from Fajardo

★★★★★★★★★★5.0 · 199 reviews · from $66Top rated

Kayak Fajardo’s Laguna Grande with a marine biologist, mangroves, sunset, wildlife, and glowing water for $66.90.

“Fun kayaking through an area you would not see otherwise. Neat experience kayaking in the dark and seeing the bay, but when it's time to see the luminescence, they put all kayaks tight together and cover with tarp. You need to hold the tarp up with one hand and use your other hand to splash the water to see them "light up". However, the kayaks are crammed in so the person in the front can't fit their hand in the water without it being jammed between twi kayaks. What was thought to be the highlight of the trip was disappointing so 4 out of 5 stars. Redeeming factor, as you…”

9.Bioluminescent Bay Night Kayaking, Fajardo

★★★★★★★★★★4.0 · 45 reviews · from $79

Paddle Laguna Grande at night, learn about bioluminescent plankton, and explore Fajardo’s mangroves in a small guided kayak group.

“We went on a night with a little over a half moon -- definitely wasn't as amazing as others who recommended the tour to us said. Maybe it would be worth it on a completely dark night. They had a tarp to help block out the light, but it still wasn't that impressive. We were already in the area from a hiking trip, but I wouldn't go out of my way if I had only been in San Juan to go. The guides were great though!”
