Volusia County has 47 miles of beach along the Atlantic Ocean. Each year, the International Coastal Cleanup is held around the world, with millions of volunteers putting in time do beach cleanups. There are several locations you can go to in order to officially participate in the International Coastal Cleanup in Volusia County (although you can always do a beach clean up anytime and anywhere on your own). The clean up is scheduled for September 21, 2019.
There is a list of locations that are being coordinated by the county, and a couple that are being organized by others. Whether you put in 30 minutes or an hour, collectively it will all help the ocean to be cleaner. This is a great family friendly activity.
