The path winds its way from the Tennessee Riverwalk in the heart of Chattanooga to Camp Jordan in East Ridge - open to walking, running, biking, even paddling by canoe.
The South Chickamauga Creek Greenway - which covers about a dozen miles, cost 16 million dollars and took nearly three decades to complete - is now fully open to the public.
The Trust for Public Land partnered with the City of Chattanooga on the project.
On Sunday, a ribbon cutting will be held - one of several events this month to celebrate the Greenway.
Daniela Paz Peterson is with The Trust for Public Land.
