Sonneberg is connected by regional trains from Coburg and the Franconian side of the border, with onward links toward the Thuringian network. The station is close to the centre and makes the town easy to visit without a car.
By road, Sonneberg sits south of the Thuringian Forest and north of Coburg. It is a logical stop if you are moving between northern Bavaria and southern Thuringia, especially with children or a taste for unusual local museums.
