Known as "the city that guards the sun of the Caribbean" La Metrópolis del Sol Naciente, Fajardo is on the east coast of Puerto Rico, north of Ceiba and east of Luquillo.
One of the main attractions is the Bio-Luminescent Bay. A 1.5 hour tour, you will kayak in through a Mangrove forest at night to the bay, where luminescent plankton glow bright blue every time the water is disturbed. Most tours cost $45, and combo packages with tours of El Yunque Rainforest are available and quite a good full-day trip.
