Explore Rainforests, Coral Reefs, and Glowing Bays
San Juan is renowned for its historic walled center, museums and casinos, but Puerto Rico is also rife with outdoor attractions. Hike El Yunque, the only tropical rainforest in the US National Forest System. Dive among coral reefs off Mona Island, home of sunken Spanish galleons. On a moonless night, tour the phosphorescent bays at Las Cabezas de San Juan Nature Reserve or Vieques’ Mosquito Bay, where tiny organisms illuminate the waters.
