The beaches in Galicia to see bioluminescent plancton this summer

Known as "mar de ardora", the bioluminescent glow is lighting up summer nights along several beaches in Galicia, Spain. According to Hosteltur, the phenomenon is caused by the microorganism Noctiluca scintillans, which flashes a neon blue when waves break or swimmers move. Top spots include As Catedrais, Rodas (Cíes Islands), San Martiño and O Vicedo.

Here's the lesson for our industry: natural wonders like this have huge potential to attract experience-driven travelers. If Dominican Republic identifies and markets similar events (mangrove bioluminescence, turtle nesting, humpback whale migrations), we can stand out from generic sun and sand.

Hoteliers and tour operators can organize guided night excursions to dark shorelines, invest in low-impact lighting that won't scare off the plankton, and add this attraction to all-inclusive packages. Many Dominican beaches already have the right conditions for this type of nature tourism, yet it remains largely untapped.

The keys to repeating Galicia's success: pick moonless nights, check tide charts, and spread the spectacle on social media. A well-shot video of that glowing neon water is worth a thousand brochures.
