The SweetWater 420 Fest is an annual event presented by SweetWater Brewing Company in Atlanta, Georgia held on a weekend closest to Earth Day. In 2014, the festival announced new home in Centennial Olympic Park.
As an Earth Day celebration, the SweetWater 420 Festival hosts charities, non-profits and environmental workshops in its Planet 420 Non-Profit Village alongside the live music stages, food trucks, artist market, and beer stations.
The festival also hosts an annual SweetWater 420 Fest 5K, in which participants run through the park and surrounding neighborhood in a USATF qualifying course on the Saturday morning of the weekend festival.
