The patron saint of Suno is Saint Genesius of Rome, celebrated on 25 August in the Pieve di San Genesio.
The area is largely hilly: on these hills both the strawberry grape, celebrated with a traditional festival in August, and wine are produced, so much so that the town belongs to the Wine Towns network. The town also holds the church of the Santissima Trinità and the Suno Railway Museum.
