Join the Roundhouse Aquarium Team to clean up our shoreline at the 42nd Annual Coastal Cleanup Day 2026. The Roundhouse is working in partnership with Heal the Bay and the California Coastal Commission as one of many clean up sites throughout the state of California to help clean the environment from summit to sea. Check in at the base of the Manhattan Beach Pier starting at 8:45 a.m. (Full details at the event link)

Donations are welcome to help the Roundhouse continue to provide educational events to the community and students, and to enable visitors to visit the Roundhouse Aquarium year-round free of charge.
