St. Louis is a beautiful city with plenty to offer — from Grand Center to The Hill, it never takes guests long to discover how full of character this city truly is. The city is also abundant in historical attractions and green spaces; in fact, 1,300-acre Forest Park is 500 acres larger than NYC's Central Park and houses everything from statues and memorials to a science centre and a golf course. Of course, no tour of The Gateway to the West is complete without taking in the awe-inspiring Gateway Arch, one of the tallest arches in the world.
