Maritime Aquarium at Norwalk, Norwalk: How to Visit and What to Do Nearby

The Maritime Aquarium at Norwalk occupies a converted 1868 iron works foundry along the Norwalk River in downtown Norwalk, Connecticut, opened in 1988 with a focus on Long Island Sound species. Indoor tanks hold sand tiger sharks, harbor seals, river otters, and jellyfish alongside exhibits on Sound ecology and regional maritime history. The IMAX theater was replaced in 2023 with a 4D theater showing rotating nature films. Admission runs around $30 for adults with discounted evening and membership rates. The aquarium serves as the public face of Long Island Sound conservation education. When in Norwalk it's worth considering not only but another main attraction like Sheffield Island Lighthouse.
