We are pleased to announce that the return of HarmonyFest 2026 on Sept 6th! Harmony Fest is a free premier outdoor festival that takes place the Sunday of Labor Day weekend in Historic Downtown Three Rivers. It has been an integral part of our community since its inception in 1993—bringing people together in celebration of our cultural and ethnic diversity through music, food, art and social connection. Please contact the DDA (trdda@threeriversmi.org), if you would like to volunteer.
