Andreas was well orgonized and explained the route and how the day will unfold.  He was very informative about nature, he knew all the plants and gave us very interesting facts. We all loved the walk with him because of his friendliness, caring about the group and passion for nature.  His knowledge about astronomy was amazing and overall we had a fantastic trip with him. We will defenitely do a walk with him again. By Maricha Elliot-Wilson
