Ride the 8-mile long Grant's Trail, which runs by The Lodge at Grant's Trail, Grant's Farm and an off-road BMX bike park. This former railroad provides a flat surface perfect for biking, jogging, in-line skating and other recreation.
Once Ulysses S. Grant's personal farm, Grant's Farm now belongs to the Busch family and houses 100 different species of animals, among many other attractions. Ride a tram to see these animals in their natural habitat, and meet a few in the petting areas.
Let your wild side out at the Saint Louis Zoo. Check out exotic animals from all over the world, from Africa to Antarctica. Grab a train ride for a narrated tour around the zoo or get up close and personal with the animals in Discovery Corner and other exhibits and attractions.
Bring your magnifying glass to the smallest tourist attraction in St. Louis. The Miniature Museum of Greater St. Louis is devoted to miniatures of all sizes, from small to itty-bitty to teeny-tiny. Visit the gift shop, take a class, or attend the twice-yearly Gateway Miniature Fair. The museum is open Wednesday through Sunday.
