River Days Festival in Portsmouth
River Days fills Portsmouth's Ohio River waterfront every Labor Day weekend with four days of live music, boat races, a parade, and a midway of rides and games along Fourth Street. Billed by the city as the longest continuously running festival in Ohio, having marked 58 years in 2021, it pairs free downtown activities with an admission-gated riverside area for concerts and races.
Its river-town identity gives southern Ohio useful coverage.
