Every now and then, the trail takes you right along the coast, but on a rather rugged terrain over the rocks. Not always pleasant to go, since it requires concentration and good balance abilities. Once you twist one of your ankle here, the dream would be over.



Even in this seemingly desolate surrounding you'll find somehting wonderful to explore. Many of the rocks and even tree trunks are covered with lichens, ranging from vivid yellow over a satured orange down to lush leave green, finally fading into a "friendly" black.



Until now I did not know that I actually was looking at one of nature's successful symbiosis of two organisms, a fungus and a lichen. I think the color determing part here is the fungus. If the mutually nurishing pair lacks water or moisture, the color turns black, but they'll survive.
