Be sure to have plenty of gas in the tank, because Hannover is well worth a detour. Situated 30 miles from Petershagen, it’s home to some wonderful attractions, such as HDI Arena and Marktkirche. Nothing screams fun like a road trip does, so keep on cruising to Bremen. It’s 45 miles away and also features a few rewarding sights, such as Bremen City Hall and Weser Stadium.
