Obří akvárium

Obří Akvárium — Giant Aquarium — is one of Prague's more impressive indoor attractions for families, featuring large-scale tanks filled with a wide range of marine species including sharks, rays, tropical fish, and freshwater exhibits. The sheer scale of the main ocean tank is the centerpiece of the experience, and it genuinely delivers on the promise of the name.

For younger children, the aquarium provides that essential combination of wow factor and accessibility. Tanks are positioned at eye level for kids, the lighting is atmospheric without being disorienting, and the variety of species on display keeps attention moving from one exhibit to the next without the interest drop-off that can happen at smaller aquariums.

Feeding times are worth planning around — check the posted schedule at the entrance and time your visit to catch at least one. Watching staff feed sharks or rays is one of those aquarium moments that kids remember and retell afterward.

The facility is stroller-friendly and the layout flows logically from one section to the next. Rainy days are when Obří Akvárium earns the most appreciation from families — it's a full-morning activity that keeps everyone engaged regardless of what's happening outside. Weekday visits are notably calmer than weekend ones, so if your schedule allows flexibility, mid-week mornings are the sweet spot.
