To reach the starting point of the hike, park your car at the stated coordinates. If you come from the west, go forward about 100 metres. There is a hotel, where you can turn safely.
Although the hike is not very long, be aware of the sun and pay attention to snakes. I have not seen any of these animals, but I can imagine that they are living there.
Enjoy the wonderful view over the village Psakoúdia, Sithonia and Kassandra!
