At this leafy, 735-acre retreat, hiking paths wind through the trees, paddleboats navigate Porter Lake, and hungry ducks float on a small pond. The zoo, where Theodore Geisel—better known as Dr. Seuss—found inspiration for his children's books, is home to nearly 200 animals, from black bears and bobcats to lemurs and wallabies. It's manageable in size, and spotting animals in the exhibits is fairly easy, which makes this an especially good stop for families with small children. Another plus: you can purchase small bags of food from the gift shop and feed many of the animals. Leave time to explore the park after you finish the zoo.
