National Park Week is an annual celebration of America’s national parks. Gateway Arch National Park and Gateway Arch Park Foundation are celebrating by helping to preserve and protect St. Louis’s historic riverfront and the Mississippi River, which flows along the boundary of Gateway Arch National Park. The annual St. Louis Riverfront Clean-Up will take place on Saturday, April 25th from 9 a.m. – noon.  

After removing more than 2,000 pounds from trash and recyclables from the river in 2025, Gateway Arch National Park and Gateway Arch Park Foundation have teamed up again with Great Rivers Greenway, Living Lands & Waters, Republic Services, and Missouri Stream Team to clean up our Mighty Mississippi.   

They’re asking YOU and your friends and family to join in lending a helping hand to keep the front yard of St. Louis clean, vital, and welcoming.
