The route starts at the stop "Decin-Certova Voda" and initially follows the yellow and then the green trail uphill to Maxicky (Maxdorf).
From Maxicky, you then follow the yellow trail to Decin. In the settlement "Cerveny Vrich" (Rothberg), you leave the yellow trail and initially continue a bit along the street of the same name. Then turn left into the next street and walk downhill. At the end of the street, turn right again and follow the street named "Belska" uphill a bit before turning left into the forest and heading towards the zoo.
After a short ascent via switchbacks, follow the red trail to the left to Pastyrska Stena (Shepherd's Wall), where a restaurant of the same name sits atop a small castle.
From Pastyrska Stena, a path runs behind the castle to the zoo in Decin, which is definitely worth a visit.
From the zoo in Decin, you then go down the "Zizkova" street into the town, passing a Jewish cherry tree and almost directly to Decin station, where the route ends.
