Goslar (31.07 miles / 50 km)

This city in the northwest of the Harz is one of the nice-looking cities that are on the UNESCO heritage list and because of the many monumental buildings in half-timbered style, nice to see. The city centre is a pleasure to stay at because of the many terraces and old, stately buildings.
You can sniff up history and technology in the famous Rammelsberg mines, high above Goslar.
