Furthermore, it is also the main port and seafront resort in the Bruges subdivision. This explains why the name Zeebrugge literally means “Bruges at Sea”. The limited light pollution also makes this area superb for stargazing. Sometimes you will have an incredible sight of the Milky Way. All this makes the Lough Hyne Nature Reserve a truly special place that is absolutely worth a visit.
It’s sometimes referred to as the “Puerto Rico glowing lake” thanks to its lagoon-like shape. Which means that with a mere 2.5-hour flight from Miami you can experience this natural nighttime phenomenon in person. The bio-bays glow is caused by micro-organisms which glow whenever the water is disturbed, leaving a trail of neon blue. The best time to view the bioluminescent bay is when the night sky is dark due to little or no moonlight. The bioluminescent bay atLa Parguera, located in Lajas at the southwestern corner of Puerto Rico, is the only one where motorboats can come in and out.
Somewhat unique to St. Croix, Salt River Bay is home to bioluminescent comb jelly fish in addition to the more common dinoflagellates. The glowing tide phenomena, spanish naked beach which is actually “red tide,” is caused by a sudden algae bloom. When disturbed , the algae reacts with oxygen and creates a bright blue glow.
Our tour guide told us that this disaster actually brought in more organisms, and the bays have never been brighter. The best time to see the bioluminescent is when the night is the darkest, which usually falls in five days after the full moon in warm summer months, from mid-May through early October. Therefore, the ecological conditions are more critical and need to be present for the microorganisms to get stuck there in the first place. For instance, if the giant ring of mangrove trees in Vieques’s Bay, which keeps the sand bars protecting the bay in place, are ripped out in a storm, the bio bay will be lost as well. On average, there are about 700,000 of Pyrodinium bahamenseper gallon of water in Vieques’s bay.
Although you won’t find beaches at La Parguera, it is blessed with beautiful cays. You can rent a boat and explore the cays on your own or find a local company to take you on a guided tour. This Puerto Rico bioluminescent bay is part of the Cabeza de San Juan Nature Reserve. To access it, you’ll paddle through a narrow canal lined with mangroves to Laguna Grande, which is partially protected by a coral reef. When gently agitated — such as by a kayak paddle or ocean waves — dinoflagellates emit luciferin, a chemical that creates a bright glow when it combines with oxygen.
What sets Laguna Grande apart is that the bio bay is actually a lagoon, nestled within an area of spectacular natural beauty. The lagoon forms part of Las Cabezas de San Juan Nature Reserve, one of the most gorgeous and ecologically important areas in Puerto Rico—seven eco-zones thrive within a compact area. The ability to visit the bio bay on a day trip from San Juan is a huge part of the appeal. As such, you should expect large numbers of visitors, especially on the weekend and holidays.
