Puerto Rico offers an idyllic escape for your clients. With warm weather and crystal-clear waters, this Caribbean island is the perfect setting  for sensational swimming,snorkeling, and sunbathing in pristine beaches. 

But there’s more to Puerto Rico’s oceanfront than dazzling shores and vistas. Here are other captivating things you’ll find-along the island’s coastline.

1. A glow-in-the-dark bay
It’s official: Puerto Rico has the world’s brightest bioluminescent bay. According to the Guinness World Records, Mosquito Bay – just off the Puerto Rican mainland on the smaller island of Vieques – is the most dazzling of all the areas in the world where the glow-in-the-dark plankton, known as dinoflagellates, thrive. 

The phenomenon is quite incredible to witness – when agitated, millions of these bright organisms become visible as the waves lap upon the shore. The beach looks as if neon-blue glitter has been sprinkled across it each time the water recedes- and glows with every movement as kayakers disturb the plankton. 

Whether viewed from the shore- or even upon the water in a kayak or small boat, your clients will never forget the sight of the glow-in-the-dark bay in Puerto Rico. 

2. An old Spanish castle and the walled city
Perched on a hill in San Juan, the capital of Puerto Rico, Castillo San Felipe del Morro is a surprising sight. This huge fortress is a 16th-century citadel, built by the Spanish in the 1500s to defend the island from pirates and invasions. The impressive castle was retired by the US .

Today, this important piece of Puerto Rican history is well worth a visit. Send your clients here and not only will they get a fascinating insight into the island’s 500-year history, but also spectacular views out to a seemingly endless ocean. 

3. A wildlife refuge
On the island’s southwest coast, Cabo Rojo National Wildlife Refuge is a stunning landscape that teems with intriguing creatures. Its protected beaches, dry forests, and mangroves are the perfect habitat for all manner of wildlife, from frogs and toads to lizards and birds. Your clients might see yellow-shouldered blackbirds or bright yellow mangrove warblers, and more fascinating creatures.

The visitor center here is a brilliant place to understand the ecosystems that define the Caribbean, but the best thing for your clients to do is get out there and explore the nature trails by foot.
