Good itinery that suited our needs for more challenging walking; a self-guided hut to hut route. We have used Colletts previously and enjoyed our past experience. We really appreciated the accuracy of the route discription and information, and that the grading was right. In the past we have been disappointed with what we have felt was inaccurate grading. The staff were excellent. A lovely circuit of the Zugspitze, good scenery. We would definnitely be intereted in other self-guided hut/hotel to hut/hotel itneries throughout the Alps.
