Coastal Cleanup Day

9:00 am to 12:00 noon

Participate in the 25th Annual Coastal Cleanup Day at Riley Wilderness Park. We will focus on clearing trash from Wagon Wheel Creek to prevent refuse from reaching the ocean from our watershed. We are also trying on making this year's event as close to zero waste as possible. We encourage you to meet at the Visitor Center with a reusable water bottle (which we can refill here) and any large grocery/retail bags from home for reuse (extra bags will be on hand). Cut and paste the following web address into your browser for more Coastal Cleanup day information and locations: http://www.ocparks.com/newsroom/default.asp?Show=1001869&subshow=A
