La Parguera Bioluminescent Bay
Lajas
La Parguera gives the main island its own place in Puerto Rico’s bioluminescent story. While Vieques remains the better-known headline, this south-western experience is valuable for travellers shaping an itinerary around the main island and wanting a night excursion tied to the coast and boating culture of Lajas. It sits below Mosquito Bay because the setting and reputation are less singular, but it still earns inclusion as a real regional anchor. It helps balance the guide geographically and shows that Puerto Rico’s best-known natural phenomena are not confined to one offshore island.
