Coastal Cleanup Day 2025

Saturday, September 20th, 9AM - 12PM

At the base of the Manhattan Beach Pier

Join the Roundhouse Aquarium Team to clean up our shoreline at the 41st annual Coastal Cleanup Day 2025! We are 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.

Be sure to check-in at the base of the Manhattan Beach Pier starting at 8:45AM, then head to the safety talk on the northside of the beach and the supplies station before heading out to start cleaning. When you are ready to leave, please bring your trash and data cards to our weigh station next to the check-in station, so we can weigh your trash and collect your data cards before 12PM noon. We send all the trash data from our site to the California Coastal Commission every Coastal Cleanup Day! SEA you soon!

Donations are suggested and welcomed to help us continue to provide educational events to the community and students, and to enable visitors to visit the Roundhouse Aquarium year-round free of charge. Thank you for your support!
