The Hoysala-era Harihareshwara temple and Tungabhadra riverfront make Harihara the strongest architectural extension from Channagiri.
Where it fits
Use this as a separate road extension, not as padding inside a Channagiri town day. Arrange both road legs locally, keep heritage and wildlife stops to daylight, and leave enough margin for the return.
Plan with evidence
Official district and tourism sources establish the destination; map data supplies location context. Fees, timetables and facilities should come from the operator or posted notice.
