Tucked into the historic FirstEnergy Powerhouse in Cleveland’s Flats, the Greater Cleveland Aquarium is Ohio’s only freestanding aquarium — a compact but captivating walk through the waters of the world.
Worlds beneath the surface
Journey from local Ohio rivers and the Great Lakes to tropical seas and a steamy Indonesian habitat. The showstopper is the 230,000-gallon shark tank with a walk-through SeaTube tunnel — sand tiger sharks gliding right over your head. Don’t miss the touch pools with rays and the playful exhibits perfect for kids.
A great day in the Flats
The aquarium’s industrial-chic setting in the old powerhouse is part of the charm, and it pairs perfectly with a day exploring the revitalized Flats East Bank along the Cuyahoga River.
