The Grunewald Forestry Office has painted the symbol for the Havel Heights Trail on trees and stones. Sometimes you have to search a bit, but actually the path is excellently signposted. Under the motto of water (blue), knowledge (yellow) and forest (green), a signpost has been created that is a bit reminiscent of a windmill. The Havelhöhenweg belongs to the 20 green main paths in Berlin (path number 12), so you can also follow the dark blue-white-dark blue sign with the 12. However, we have not discovered this signage as often as the colorful logo for the hike on the Havelhöhenweg.
