Downtown Aquarium Denver

Downtown Aquarium is an entertainment and dining complex situated on a 17-acre site adjacent to the South Platte River in Denver, Colorado. The 107,000-square-foot facility houses more than 500 species of animals across freshwater and marine exhibits, a full-service Aquarium Restaurant, the Dive Lounge, the Nautilus Ballroom, and amusement attractions — creating a distinctive backdrop for private events. Three dedicated event spaces accommodate a range of group sizes and occasions. The Nautilus Ballroom, featuring hand-painted ceilings and beaded chandeliers, seats up to 250 guests and expands to 500 for standing receptions. The outdoor Observation Deck offers views of the downtown Denver skyline and hosts seated gatherings of up to 100. The Dive Lounge provides an upscale setting well suited for cocktail receptions and smaller celebrations. All-inclusive event packages include an in-house Event Manager, professional service staff, and the venue's culinary team. Downtown Aquarium is accredited by the Association of Zoos and Aquariums and managed by Landry's Restaurants, Inc.
