Why you should go…

Housed in the magnificently restored Union Station, this two-story aquarium sends you from Missouri's rivers to the open ocean, with touch pools, a shark habitat and playful otters along the way. Step outside and the fun keeps rolling: the 200-foot St. Louis Wheel, mini golf, carousel and the station's famous fire-and-light show over the lake.
