Andreas is my idea of "the perfect guide". I found him extremely knowledgeable about nature, history, geology, archaeology, and a lot more. It was wonderful being guided and informed / educated by him during the three days of the hike. He made the plants, nature, mountains, birds, insects and everything we encountered come to life and so much more interesting and understandable. Over and above his excellent knowledge he is also a friendly and most likeable person. He is the type of person that instils confidence and is definitely the type of person that I would like around in a crisis. I want to thank Andreas for the most pleasant trip I had - your passion for nature and life in general is amazing and contagious. You will definitely see me again on one (and more) of your tours in future.
