The arboretum of the Güth House in Hoste is a discreet treasure hidden in the heart of the village. You can admire, among other things, a giant redwood of America. In this arboretum whisper stories of trees... or would they be trees in history? Indeed, what happened after the visit of a President of the United States of America to King Louis XVI? What has a Jesuit left to evangelize China? The use of such a tree was decisive during the great battles of the Hundred Years War, others advanced medicine. These stories are told during the visit, led by an enthusiast. The Saturday tour will be in French and German simultaneously, the Sunday tour will be exclusively in French.
