The best things to do in St. Augustine with kids are the St. Augustine Alligator Farm Zoological Park and the Castillo de San Marcos, and each one fills a good morning. The Alligator Farm comes first for most families. It has every living species of crocodilian, plus lemurs and birds, and its paths are shadier than you would expect. The Castillo is the oldest masonry fort in the country, with big grassy fields around it where kids can run off energy after the history.
