How it works
Ferry
20 min from Market Square by JT-Lines ferry. The island is calling.
Music & drinks
DJ sets on the sea-view terrace. Cocktails, wine, and island vibes from sunset until the last ferry.
Midnight sun
Dance under skies that never go dark. Theme nights, surprise sets, and the best crowd in Helsinki.

The vibe
IISI parties aren't club nights crammed onto an island. They're sunset sessions that build naturally — from afternoon wine on the terrace to full dance floor by midnight. No dress code, no VIP rope, no attitude.
