The Aquarium of Niagara is a compact, long-running aquarium on the American side of Niagara Falls. It is smaller than big-city aquariums, but it makes an easy family stop near the state park, with seals, sea lions, penguins, fish, and hands-on exhibits.
Its Great Lakes 360 expansion adds displays on the Niagara River and Great Lakes ecosystem, giving the visit a stronger local focus. It works best as a short indoor break between gorge and waterfall sights.
