O Grove Aquarium is a compact family stop focused on the marine life of the Galician coast. Tanks introduce fish, shellfish, and Atlantic species connected to the rias, fishing, and seafood culture that shape the town.
It is not a major aquarium by big-city standards, but it fits O Grove well. Visit it on a cloudy day, or use it to give children some context before a boat trip, beach walk, or seafood meal.
