Photos: How biggest event yet at Atlanta’s largest park turned out Josh GreenTue, 04/21/2026 - 17:15The first foray for Atlanta’s largest greenspace as a full-fledged concert festival venue was a good-vibes success that will benefit regional waterways, according to organizers. Following a venue switch from the eastside, longstanding SweetWater 420 fest drew thousands to Shirley Clarke Franklin Park (formerly Westside Park) despite record heat Friday and Saturday, marking the largest event to date since the greenspace opened more than four years ago. Festival organizers tell Urbanize Atlanta roughly 8,500 concert goers attended performances by 13 eclectic artists at the 21st incarnation of SweetWater 420 Fest across the weekend. Top draws included headliners Umphrey’s McGee and Thievery Corporation, alongside Chromeo and Cimafunk. A portion of every beer sale was donated to local causes the Waterkeeper Alliance and Chattahoochee Riverkeeper.Chromeo performs an electric set during sunset at SweetWater 420 Fest on Saturday.

The venue switch aimed to increase capacity for a bigger, greener, and more accessible concert experience, organizers have said. Have a look at how 420 Fest went down—or a reminder, in case your memories of being there are cloudy—in the gallery above. **…**Follow us on social media:Twitter / Facebook/and now: Instagram  • Four years later, has Atlanta’s largest park lived up to expectations?(Urbanize Atlanta)TagsShirley Clarke Franklin ParkWestside ParkGrove Park NewsSweetWater 420 FestSweetWater BrewingSweetWater Brewing CompanyAtlanta ParksAtlanta MusicAtlanta Music FestivalsAtlanta Music VenuesRival EntertainmentPullman YardsPratt Pullman DistrictBroadstone PullmanMusic festivalsAtlanta FestivalsDiffusionWaterkeeper AllianceChattahoochee RiverkeeperImagesAerial image showing one section of Shirley Clark Franklin Park in June, looking east toward Midtown and downtown.
