Bahía de Jobos, also known as Jobos Bay National Estuarine Research Reserve, is a federally protected estuary in Puerto Rico. This intertidal tropical ecosystem is a haven for diverse wildlife, with seagrass beds, coral reefs, and mangroves dominating the landscape. The bay itself covers nearly 3,000 acres, encompassing coastal wetlands and 15 offshore mangrove cays known as Los Cayos Caribes. Visitors can learn about this unique ecosystem at the Jobos Bay National Research Reserve visitor center, featuring exhibits and educational displays.
