An Insider’s island vacation: the most unique things to see in Puerto Rico

Bioluminescent Bays
Each night, thousands of single-celled organisms give off light from under the waters of Laguna Grande, La Parguera, and Mosquito Bay. Puerto Rico is one of the few places in the world where this phenomenon takes place!
Why to Go: Have you ever gone swimming in a glowing ocean before? Enough said.
Caving Adventures
Puerto Rico is home to some of the longest and deepest caves in the world, offering some of the most out-of-this-world experiences in the Caribbean.
Why to Go: At the Camuy Caves (the Parque de las Cavernas del Rio Camuy), visitors can take a tram tour of the caves or rappel down a cliff into the cavernous openings – so every traveler can experience this adventure at their own speed.
Arecibo Observatory
One of the most unique things to see in Puerto Rico? How about the world’s largest radar-radio telescope!
Why to Go: Explore the observatory’s viewing platform and interact with two levels of interactive exhibits on planetary systems, meteors, and weather. Plus, you’ll be at the filming site of scenes from the movies “Contact” and “GoldenEye!”
The Panoramic Route
Traversing the interior mountains of Puerto Rico, the Ruta Panorámica is a network of roads with spectacular views around every bend.
Why to Go: Not only is it an exciting journey, but the route covers stunning parts of the island that most visitors miss.
Offshore Islands
Vieques Island – the more developed of the two – is home to nearly deserted beaches and top snorkeling. Culebra Island is even more remote, with a wildlife refuge and amazing coral reefs.
Why to Go: The only thing better than a pristine beach is a pristine, deserted beach. Ditch the crowds and grab your snorkel gear – it’s time to see Puerto Rico from a fish’s perspective!
