The Basilica of Saint Apollinare in Classe, Via Romea Sud, 224, 48124 Classe RA, is in the small village of Classe, around 5 km (3 miles) to the sound of Ravenna.
Cycling from Ravenna is a good option. The route is flat and there are dedicated cycling paths, including all the way from Ravenna’s town limits to the basilica. (The cycling path is to the left of the main road when cycling towards Classe.) Several bicycle rental services are available in Ravenna, including from directly next to the station. Expect to cycle around 20 minutes each way.
