Be sure to have a full tank of gas, because Nuremberg is worth making a detour for. Situated 20 miles from Heideck, it has a few fabulous attractions, such as Nuremberg Castle and Nuremberg Zoo. Nothing says living it up like a road trip, so keep on cruising to Bamberg. It’s 55 miles away and also has a few worthwhile sights, such as Bamberg Cathedral and New Residence.
