Things to see and do La Parguera

This small island, which is part of the La Parguera nature reserve, is the only one among four others to have a beach, which is probably why it is called "La Parguera Beach". All shades of blue and green are represented, the waters are an invitation to observe the underwater life... On the beach, picnic areas are arranged, as well as a path through the mangrove. Given the size of this small piece of land, it is better to avoid weekends and vacation periods to go there.

Commonly called Bio bay, the bioluminescent bay of La Parguera attracts thousands of tourists every year. It must be said that the phenomenon is rare. There are five bays on the planet, including three in Puerto Rico. At nightfall, glows are perceptible once you enter the water. They are emitted by dinoflagellates, micro-organisms that react by signaling themselves with a small neon light when the water is agitated around them. It is therefore useless to observe the water from the shore, because nothing will happen.

La Parguera is not the most bioluminescent in Puerto Rico, but it is the least crowded, to ensure your peace and quiet. The concentration of dinoflagellates in the waters of Fajardo and especially in Vieques is much higher. Pollution and climate change have greatly affected the biological environment of these fragile microorganisms.

To ensure their survival, many factors are essential: the presence of mangroves that contribute to their feeding, a low variability of water temperature and the absence of pollution by artificial lights or chemicals. If you want to contribute to the preservation of this biological treasure, choose to visit it by kayak. Swimming causes water pollution from perfume, sunscreen or mosquito repellent that visitors often carry with them as they enter the water.
