The 1,400-acre area is one of the largest city parks in all of the U.S. Anytime is a great time to visit but September is a favorite. This is when hot-air balloons (this is where you can see them) compete in the annual Great Forest Park Balloon Race. The park is also home to several of the city’s best known cultural attractions – the art and history museums, zoo, science center and planetarium, and the Muny Theater, an outdoor musical amphitheater. The public art works, gold course, and statues blended into the landscape are amazing.
