The journey begins in the rolling hills of Cumbria, passes through the Pennines near Hadrian's Wall, and then descends to the flatlands of Yorkshire. The ferry crossing offers views of the North Sea. In Denmark, the landscape is largely agricultural with beech forests. In Germany, the A7 passes through the Schleswig-Holstein countryside dotted with lakes.

• York Minster: spectacular Gothic cathedral in York, England.
