The port from which explorers Lewis and Clark set off to discover the west, St. Louis is a lively crossroad famed for its landmark Arch, its frozen "concrete" ice cream, and its brews (root beer among them). Kids will delight in riding the science fiction-looking pod cars to the top of the Arch, romping around City Museum's outdoor playground with its airplane suspended three stories above ground, and will never forgot their visit to the zoo, science center, and art museum in the 1,300-acre Forest Park. St. Louis is a town that welcomes families like few others.

Summer is high season in St. Louis, and most attractions gear up in anticipation with special exhibits, activities, and often expanded hours. But the Midwest—and St. Louis' sprawling Forest Park in particular—is at its best in the fall, when the leaves are changing color and when most attractions are far less crowded. Steep discounts on lodging entice winter visitors, but you will have to bundle up in anticipation of snow.

St. Louis feels like the south in the summer —hot and humid, with highs in the 80's and 90's. In the winter, it feels like the north, with low temperatures in the 20's during December, January, and February. In the milder seasons of the spring and fall, dress in layers, as the cool of morning can quickly warm and then chill again in the evening.

Approximately a dozen airlines fly in and out of Lambert-St. Louis International Airport. From there the light rail system MetroLink whisks visitors to downtown and other popular neighborhoods and communities. Amtrak train service is a great way to reach St. Louis, which is on a well-serviced line between Chicago and San Antonio. Both Greyhound and the budget line MegaBus also serve the city.

Walking is a great way to take in city center sights such as the Gateway Arch, Busch Stadium, and City Museum. MetroLink does a good job of shuttling visitors to popular sights in downtown St. Louis and neighborhoods near Forest Park on the west side. But to reach many outlying attractions such as Grant's Farm, the Butterfly House, the Magic House, and the Museum of Transportation, a car is a necessity. The highway system makes it easy to scoot to these more distant points and back to downtown fairly quickly and directly.
