The Estuarium is an exciting educational public aquarium highlighting the four key habitats of coastal Alabama: the Mobile Tensaw River Delta, Mobile Bay, the Barrier Islands and the Northern Gulf of Mexico. It includes the 10,000 square foot Exhibit Hall, a 7,000 gallon sting ray touch pool, and the Living Marsh Boardwalk. This facility has 31 aquariums totaling over 30,000 gallons with more than 100 species on display. The Estuarium showcases the plants, animals, and other natural resources found in the Estuary and its surrounding marine habitats.

Through beautiful visual exhibits and engaging interactive exhibits, the Estuarium will leave you with a broader understanding of the interactions that take place in Mobile Bay, the fourth largest estuary system in the United States.
