Years of Free Festivals
Harborfest is free because people like you make it possible. Every dollar goes directly into the music, fireworks, and programming that brings 50,000 people to Oswego every summer.

Festival maps, directional signs, and printed schedules that help 50,000 people navigate the grounds.

T-shirts, meals, and coordination for the 200+ volunteers who keep the festival running every year.

Sound, lighting, and equipment that makes the live music experience what it is across all three stages.

The Grand Finale over Lake Ontario costs hundreds of thousands to produce. Every larger gift brings us closer to another year of lighting up the sky.
