Puerto Rico
Caribbean
A Caribbean archipelago and United States territory east of Hispaniola, Puerto Rico pairs the walled colonial core of Old San Juan and its UNESCO forts with a mountainous rainforest interior, the winter surf coast at Rincon, and the world's brightest bioluminescent bay off the island of Vieques. Its Afro-Puerto Rican music culture of bomba and plena runs deep, and the offshore islands of Vieques and Culebra hold some of the clearest water in the region.

- FajardoJan Feb Mar Apr DecFajardo is the easiest place in Puerto Rico to see a bioluminescent bay, and for many visitors it is the introduction to the phenomenon before or instead of the trip to Vieques. Laguna Grande sits inside Las Cabezas de San Juan, a protected headland reserve on the northeast tip of the island, and unlike a fully enclosed bay it is a lagoon linked to the sea by a long, tunnel-like mangrove channel. Guided kayak tours paddle that channel in the dark, the mangroves closing overhead, then open out into the lagoon where the dinoflagellates glow blue-green off every stroke. It is less remote and more accessible than Mosquito Bay, only about an hour from San Juan, so it works as a night out on a wider Puerto Rico trip. Guides run trips year round, timed away from the full moon, and read the mangrove channel and tides so a group with no paddling experience can manage it comfortably.
- Mosquito BayJan Feb Mar Apr DecMosquito Bay on Vieques is the brightest bioluminescent bay on Earth, a title Guinness World Records made official, and paddling it after dark is one of the strangest, most beautiful natural experiences in the Caribbean. The bay is a shallow lagoon almost sealed off from the sea by a narrow mouth, which traps warm, nutrient-rich water and a huge concentration of single-celled dinoflagellates. Brush the surface with a paddle or trail a hand overboard and the organisms fire off a cold blue-green light, so every stroke throws a comet-tail of glow and fish streak beneath the kayak like meteors. Because Vieques has almost no light pollution, the effect is far stronger here than at Puerto Rico's mainland bays, and on a moonless night the contrast is dramatic. Guided kayak trips run year round, timed to the darkest part of the lunar cycle, and swimming is not allowed in order to protect the microorganisms that make the whole thing work.
