One of the most recognisable rock formations in Harz mountains - Teufelsmauer - is a great hiking spot.
This hike started in small village Timmenrode and not in Blankenburg like many guides describe. Starting from Timmenrode makes it possible to immediately reach the famous rock formations called Hamburger Wappen.
The trail is not long however it is quite demanding as you walk on the ridge with a very narrow paths and secured passages.
It is however a really great hike beautiful views.
