A visit to the San Diego Zoo is home to over 4000 animals of 800+ species, cleverly encases these living tales within habitat-themed exhibits, from deserts to rainforests. Innovating with cageless displays revolutionized the zoo experience, making you feel more like a globetrotter on safari than a traditional zoo visitor. The zoo's edutainment approach makes learning fun— not just about animals. Surprise, it's also a botanical garden housing 750,000 rare and endangered plants. There's a downside, though—it's impossible to cover it all in a single day. Map out which parts must see or return for a second day.
