ABOUT THE SIRENS BALL
First conjured from the depths in 2016, the Sirens Ball has since become a shimmering centerpiece of the Portlandia Mermaid Parade & Festival, a three-day celebration of all things aquatic, mythical, and magical.
This immersive evening gala also serves as a fundraiser for the PNW Mermaid Confluence, supporting creative community-building and mermaid-centered gatherings across the Pacific Northwest.

The Sirens Ball 2026 goes offshore for a very special immersive River Cruise Experience!
Murder on the Willamette is a live-action murder mystery river cruise inspired by classic whodunit games but infused with siren fantasy and aquatic myth. Set in a 1920s–30s riverboat world, the experience blends live music, performances, and interactive storytelling. Guests may choose their level of participation, solving the mystery alongside the characters or simply enjoying the story as it unfolds.
During this three-hour river voyage, guests will enjoy lavish, heavy hors d'oeuvres, a no-host bar, and the chance to claim grand prizes, whether by solving the murder mystery or rising to claim the title of Majesty of the Waters 2026.
