As the only zoo in Puerto Rico, this 14-acre (5.7-hectare) attraction is worth a stop if you’re traveling with kids. The birdhouse has a nifty elevated walkway allowing visitors to look down on colorful tropical birds (there are also nonlocal species, such as eagles, hawks, and owls). Surprisingly, the Zoo features an “African safari” exhibit (giraffe, lions, elephants, zebras, and rhinos) along with areas devoted to Puerto Rico’s animals (including the jaguar). You can see the entire zoo in 2 hours.
