The San Antonio zoo is one of the best places in the city to grab your camera and go for a stroll. Spread over 56 acres, the zoo houses some 3,500 animals representing more than 750 species! It's a wonderful place to bring your kids and let them burn off some of their energy, while getting a great learning experience at the same time. The zoo is open 365 days a year and offers several different exhibits and special events throughout the year. You can avoid lines by showing up early in the morning or arriving later in the afternoon.
