About the event
Celebrate with the Inland Ocean Coalition and Help Protect Our Ocean at the Masquerade Mermaid Ball!
The 6th annual Masquerade Mermaid Ball will be held at Junkyard Social Club, a creative community space in beautiful Boulder, Colorado on Saturday, October 18. The event will feature music and dancing, delicious food and drinks, an online auction, costume contest, pirates, and, of course, mermaids and mermen! The Masquerade Mermaid Ball is the best place to mingle with other ocean lovers and celebrate our connection to the ocean and the amazing ability we all have to make a difference - no matter where we live.
All proceeds supported our mission of building land-to-sea stewardship. We do this through protecting our ocean, watersheds, and climate, and working to prevent plastic pollution.
This year is a special one: we are making a splash to celebrate 15 years of Inland Ocean Coalition defending the ocean from the Colorado Front Range! We can't wait for you to join us for this fundraiser event.
