Join us for the 52nd annual Founders Day at DeRivera Park in downtown Put-in-Bay, Ohio.
The day kicks off with the Pooch Parade at 10 AM, followed by Founders Day festivities from 11 AM to 4 PM. Bring your pup, dress them up, and start the day with one of the island’s most fun traditions before heading into the main event.
Founders Day celebrates the legacy of Jose DeRivera, the Spanish merchant who purchased South Bass Island in 1854 and helped shape the community we know today.
Throughout the day, DeRivera Park will be filled with local vendors and activities. It’s a laid-back, family-friendly event that highlights the island’s history and community.
Vendor registration closes on May 23, 2026.
