### Tiefe Kohlstelle Around the 5 km (3.1 miles) mark, you'll reach Tiefe Kohlstelle, a historically significant area known for its old mining activities.

There are benches and picnic areas where you can rest and enjoy the scenery.

### Navigation and Safety The trail is well-marked, but it's always a good idea to have a reliable navigation tool.
