Green River Fest is a free, eco-themed summer festival on the banks of the Sava river by Hendrix Bridge, running from mid-June to late September with live music, open-air cinema, workshops and stand-up comedy.
Organised by the Nature for All association, Green River Fest revives the Sava riverbank as a summer gathering spot with a solar-powered beach area, film nights and a varied cultural program that runs nightly through the season.
Entry is free. For the weekly schedule, check the official Green River Fest page linked above.
