Starting to plan ahead because they're coming for two weeks in July and I always run out of ideas by week one lol. Already have Keystone Safari and the splash pad on the list. Looking for free or cheap stuff too, kids 4 and 7. Hermitage but happy to drive anywhere in the county.
The library does a great free summer reading program and they have weekly events for kids that age. Penn-Northwest had a kids day last year that was really cute too. Mercer County 4-H has a few summer camps if you want something a bit longer. Have fun, those ages are the best!
Grove City library does a great summer reading program for the little ones, and the McConnells Mill area has easy walks if they're not too tiny. Wendell August in Grove City is fun for older kids... they can watch the metal stamping.
