The Saxon Switzerland National park is a lovely 30 minutes southeast of Dresden, and you walk through an extremely quaint traditional German town and cross the Elbe in a ferry to get there. Plenty of German tourists around, but we were the only English speakers there (including restaurant staff!)
Pictures don’t do it justice, the day was overcast and a little misty, but the walk up the mountain was gorgeous. Incredible views. Lovely day spent strolling the German countryside.
