Manilla Heritage Museum is the town's best indoor stop, housed at 197 Manilla Street beside the visitor information centre. The collection grew from local history work in the 1970s and now covers rural life, family records, photographs, documents, and the small details that explain how the district worked.
It is the kind of country museum where the value is in specificity rather than polish. Give it time if you care about the farming, railway, river, and community stories behind the main street.
