Fodor's Expert Review Downtown Aquarium

On the north side of the South Platte across from Elitch Gardens, this is the only million-gallon aquarium between Chicago and the West Coast. It has four sections that show aquatic life in all its forms, from the seas to the river's headwaters in the Colorado mountains. The 250-seat Aquarium Restaurant surrounds a 50,000-gallon tank filled with sharks and fish. Other highlights include an expanded stingray touch pool, a gold-panning area, animatronic creatures, and an interactive shipwreck. The aquarium also has a lounge with a weeknight happy hour, and the truly adventurous can learn how to scuba dive or snorkel in the tanks.
