It boasts more natural treasures than many other destinations– beaches for a wide array of water sports, rain forests, waterfalls, rivers, accessible caves and caverns and bioluminescent lagoons, just to name a few. And, don't forget, since Puerto Rico is a U.S. commonwealth, no passport is required.

If you only know Puerto Rico as the island where you change planes an route to more remote parts of the caribbean, you don't know what you're missing. There's diverse diving all around this 100- by 35 mile island, from beginner-friendly coral gardens to steep and deep walls, a handful of wrecks and some offshore islets with truly world-class reefs. Divers have discovered the underwater offerings at resort areas like San Juan, Dorado, Fajardo and Humacao. Divers also head to satellites islands of Culebra, Vieques, Mona and Desecheo

Puerto Rico's coastal waters offer scuba divers an adventure-filled collection of spectacular reefs, walls, caverns and mangroves, all filled with marine life. For example, in the Northeast, near the town of Fajardo, locals and tourists are drawn to Seven Seas Beach, a cozy stretch of shoreline featuring fine white sands. A great place to snorkel, the shallow sea bottom is teaming with tropical fish, coral formations and an abundance of other sea life. Scuba diving and snorkeling are the reason why Puerto Rico is often called "the Caribbean's best kept underwater secret."
