About St. Louis Union Station
The 1894 train station downtown now holds the St. Louis Aquarium, the 200-foot St. Louis Wheel, a ropes course, a mirror maze, a carousel and mini golf. It suits families who want to pick a few attractions and pay only for those. The Grand Hall light show is free, and a combo ticket is the cheapest way to do several things.
