Exit Leonidio heading towards Athens. When you reach the signs for “Athens” and “Lakkos,” turn left onto a dirt road just left of the fence. After a sharp right turn, you can park there.
From the parking spot, walk another 100 meters up the road. At the cairn with a wooden sign, turn right into the forest. Follow this footpath toward the three windmills. Just before the forest ends, follow the cairns guiding you up and to the left onto a narrower, steeper path.
You’ll first come across a sign for the Dornröschen sector (about 12 minutes).
Continue along the path to reach King of Thrones (15 minutes). After about 50 meters, you’ll see the U-shaped wall above.
For Peace Rock (14 minutes), walk about 100 meters to the right of Dornröschen. If you continue further along the rightward path, you can connect to War Altar (20 minutes).
