Grucci Fireworks
Saturday starting around 9:15 PM over Lake Ontario. The biggest show in Upstate New York. Not to be missed.

Marina
Oswego's world renowned sunsets, beautiful harbor and vibing river scene are a great place to stay and play.
Keep It Free
Harborfest costs hundreds of thousands of dollars to produce. Admission never will.
Every donation, membership, and sponsorship goes directly into the music, fireworks, and programming that brings 50,000 people to Oswego every summer. Oswego Harbor Festivals, Inc. is a 501(c)(3) nonprofit.
Plan Your Visit
Getting there
Oswego is 40 miles north of Syracuse. Free shuttle buses run between all venues Thursday–Sunday. Free parking available at the Romney Field House lot with continuous shuttle service to Breitbeck Park.
Good to know
Bring a lawn chair. No pets, no bikes, no drones. No outside alcohol in venues — beer and wine available inside. Performances continue rain or shine unless there's lightning or high winds.
LOVED by PEOPLE Everywhere
Crafting Smiles Since 1988
Thirty-seven summers. Thousands of lawn chairs. One lake that keeps calling people back.
Harborfest started as a community dream in 1988 and grew into one of New York's largest free music festivals. Not because of what it costs to attend, but because of what it means to the people who do. Families who came as kids now bring their own. First-timers show up once and start counting down to next year.
The lake hasn't changed. Neither has the reason people keep showing up. It's been free since 1988. The memories have been priceless.
