Roundhouse Aquarium

Welcome to The Roundhouse Aquarium

Open daily with free admission we are dedicated to teaching students & visitors about the oceans, marine life, and environment. Located at the end of Manhattan Beach Pier.

Learn more about our upcoming renovations: The Harrison Greenberg Foundation Roundhouse Aquarium Beautification Project 

We are now open in our temporary facility at the base of the pier near the south side parking lot!  We invite you all to visit us and our animals. This will be our home during the renovations, until Fall 2018.
