St. Louis has evolved into an interesting and comfortable cosmopolitan city. The downtown is vibrant with businesses, restaurants, two stadiums, the Gateway Arch and more. Parks of all sizes are scattered throughout the city and diverse neighborhoods enjoy tree-lined streets. Visitors can take advantage of museums, concert halls, theatres, an opera house, three professional sports teams, casinos, Six Flags St. Louis, a world-class zoo, water parks, ziplines, climbing walls and even a flying trapeze centre. Best of all, many of the major attractions offer free admission. Forest Park (Free) — This 1,372-acre green space (50 per cent larger than New York’s Central Park) is the city’s crown jewel. As home to the city’s zoo, art museum, planetarium, an abundance of paved and gravel bike and hike trails, two golf courses, a tennis centre, multiple softball and baseball fields, and more, Forest Park is where St. Louisarea residents come to relax and play. It also boasts the country’s oldest and largest outdoor musical theatre that offers 1,500 free seats to each performance. A trolley ($2 all day) provides transportation throughout the park from 9 a.m. to 7 p.m. (5 p.m. in winter). Anheuser-Busch Brewery Tour (Free) — Founded in 1852, this is the largest and oldest of the AnheuserBusch breweries. Three different tours are offered: the complimentary 45-minute tour includes the brewing process, aging cellars and a visit with the Budweiser Clydesdales. Two other tours that require a fee provide access to additional areas of the property.
