The sustainability festival "HÆDI - #17goals unplugged" is dedicated to the UN's 17 Sustainable Development Goals. The event shows that a reduced and resource-conserving show is very much compatible with fun and joie de vivre and does not detract from an exuberant festival atmosphere. In addition to exciting activities relating to sustainable marine and coastal protection, there will also be a lounge area, festival make-up, live music, street food and cool drinks. That's the summer feeling.
