River Clean-up & Dock Bash

April 17, 10:00 am TO 4:00 pm | Gateway Arch Riverboats | Free

Team up and meet up at the Riverboats at the Gateway Arch to help clean up the St. Louis Riverfront!


The Mighty Mississippi River is one of the largest sources of oceanic plastic debris. With your help, we can minimize our environmental footprint by collecting riverside trash and keeping the riverfront clean.


Volunteers are strongly encouraged to sign up for their shift in advance to receive swag; however, walk-ups are welcome. Please visit archpark.volunteerhub.com to sign up.


All volunteers will receive swag courtesy of Great Rivers Greenway, Living Lands & Waters and Series Six Apparel, as well as complimentary vouchers to a St. Louis Riverfront Cruise.


After the clean-up, rest and relax on the riverboat dock with live music, food trucks and drink specials.
