Free. Such a wonderful word, and not one usually associated with big-name destinations. But in St. Louis a wealth of no-ticket (and small-ticket) attractions leaves travelers with a little dough to spend on restaurants or other activities.
Forest Park, which hosted the 1904 World's Fair, has some of the best free attractions in St. Louis, including art, science and history museums, plus the zoo. The Gateway Arch charges admission (for a ride to the top), but the Museum of Westward Expansion at its base doesn't. The new Citygarden (left) mixes art with play -- also for free.

Larger than New York's Central Park and chock-full of activities, this sprawling 1,293 acres attracts locals and visitors. Crowds arrive for seasonal events such as the Great Forest Park Balloon Race (greatforestparkballoonrace.com) and the St. Louis Wine Festival (stlouiswinefestival.com). But the park's plenty busy other times, too. Kids can climb on gigantic turtles in the turtle playground or take a hayride through the park.
A shuttle bus connects many of the park's museums, all of which are free. Tour the park by foot, bicycle, paddleboat or even Segway. For general information on Forest Park, visit the Forest Park website (314/289-5300; stlouis.missouri.org/citygov/parks/forestpark/). For specifics on the park's attractions, click ahead.

Lush landscaping makes the top-notch Saint Louis Zoo as pleasant as it is popular (and general admission is free!). Six sections encompass a wide range of environments from the sub-Antarctic to tropical rainforests. Even if you don't come with the kids, definitely spring for the sea lion show tickets ($3); the show is worth it. Also popular: The Penguin & Puffin Coast exhibit (left) and the 10-acre River's Edge, which winds through wildlife from four continents (314/781-0900; stlzoo.org).

Engaging exhibits at the Missouri History Museum explore the city's colorful history, including Lucky Lindy's record-breaking flights and the 1904 World's Fair.

An Art Deco greenhouse holds seasonal floral displays in Forest Park. Built in 1936, the Jewel Box reopened in 2002 after a $3.5 million renovation.

Dynamic exhibits, including an Omnimax theater and life-size T. rex, engage more than 1.2 million visitors a year at the Saint Louis Science Center. Visitors help power the energizer ball machine that shoots balls through a three-story obstacle course. Other exhibits allow visitors to dig for fossils, play a laser harp or create a robot. In the life science lab, kids can view their cheek cells under a microscope and learn how investigators use fingerprints to solve crimes. Don't forget to visit the Planetarium, where more than 9,000 stars are projected onto an 80-foot dome (800/456-7572; slsc.org).
The 630-foot Gateway Arch soars above downtown, reflecting sunlight and glowing different colors depending on the time of day. Insiders know to cross the grass and line up at the south entrance, which generally has a shorter wait at the security check because it's farther from the parking lot. Visitors can take a four-minute tram ride through the hollow arch legs to get a panoramic view from the top. Don't miss the free Museum of Westward Expansion below the arch (877/982-1410; gatewayarch.com).
Gateway Arch 
"The Muny," as locals call it, stages family-friendly outdoor musical productions. The site dates back to 1916, when a Shakespeare troupe flattened an area between two large oaks for their performance of As You Like It. Muny is now the largest outdoor musical theater in the United States and hosts about a half-dozen musicals each year (314/361-1900; muny.org).

In 2009 Citygarden made its debut in downtown St. Louis. It mixes park and sculpture to create a life-size playground. Visitors can climb, splash or just sit and enjoy any of the two dozen sculptures and fountains. This massive urban playground has 235 trees and more than 4,000 perennials. It feels fresh, fun--and worth a couple of hours in a city that has plenty of cool places to play (citygardenstl.org).

For a taste of Italy, head to The Hill neighborhood (10 minutes South of Forest Park).

Ten minutes south of downtown in Soulard is about as close as you can get to feeling like you're in New Orleans without being in Louisiana. The district is also known as Frenchtown, and takes pride in its annual festivals, including Bastille Day and a huge Mardi Gras parade. The Soulard Farmers Market is St. Louis' largest farmers market (314/621-6221; soulard.org).
