Sisyphos

Sisyphos, a sprawling open-air complex in a former dog biscuit factory in Rummelsburg, hosts parties from Friday night through Monday morning. Its 8,000-square-meter grounds include three stages, a beach volleyball court, and a petting zoo, offering a 70% larger area than #3 Watergate. With a 24-hour license and outdoor focus, it creates a festival-like atmosphere within the city. Entry costs 15 euros—cheaper than the average Berlin techno club—but the marathon duration demands stamina only the most dedicated partygoers possess.
