Fajardo bio bay tours
Discover the glowing waters of Laguna Grande, the easiest bio bay to access from San Juan
Discover the enchanting beauty of Vieques' Mosquito Bay on our guided bioluminescent tours. Glide across the glowing waters, where millions of microscopic organisms called dinoflagellates light up with each movement, creating a mesmerizing, sparkling effect. As you kayak or boat through the bay, every paddle stroke ignites a trail of brilliant blue light, transforming the water into a scene straight out of a dream.
Arrive promptly for a brief safety meeting before embarking on this unforgettable adventure. Our knowledgeable guides will lead you on a journey into nature’s magic, offering a deeper connection to this rare, awe-inspiring phenomenon.
If you need to catch the late ferry back to the main island of Puerto Rico, you must book the 6:30 PM tour. Otherwise, you'll have to stay in Vieques overnight.
