Bahia de Fajardo, also known as Laguna Grande, is a stunning bay located on Puerto Rico's northeastern coast, about an hour's drive from San Juan. This bioluminescent bay is the main highlight, with nighttime kayaking tours offering a mesmerizing experience as the water lights up with microscopic organisms. Beyond the bay, the surrounding Cabezas de San Juan Nature Reserve is teeming with wildlife, including over 100 bird species. Hike through the lush greenery, relax on the beaches, or visit the popular Coqui Water Park for a splash of fun. For shopping, explore Fajardo's offerings, which include art galleries and local gift shops. While nightlife isn't as vibrant as other destinations, the bioluminescent bay tours provide a truly unique after-dark adventure.
