The visitors bring money to the region. However, tourism has not been without problems since the early 20th century. Different customs and traditions of holidaymakers and locals alike create conflict. Nature is not without its pitfalls either. In 1927, a teacher from Wiesbaden set off with a group of students on an autumn hike in the mountains and subsequently complained in a letter to the German-Austrian Alpine Association about his experience with unmarked paths: “After four o'clock in the afternoon, I descended from Heimgarten to Ohlstadt with about 20 students, as I had been told that the path was marked; the Baedeker also says the same. At the Käseralpe we found the last signpost. The path did not start from Heimgarten, but branched off from the ridge path between Herzogstand and Heimgarten. Immediately behind the Käseralpe, however, the markings and path suddenly stopped. So I and the students ended up in the night, we wandered around for a few hours in the swamp, forest and riverbed until we reached the path again in Ohlstadt at around 8 o'clock. So even if we were still OK, I, as the responsible guide, had to endure a few hours of worry and fear. In Ohlstadt, the innkeeper told me that this sort of thing happened almost every day. The path was not marked. The area belonged to the Weilheim section, which was doing nothing, but on the other hand refused to let other sections that were trying to find the path mark the path; numerous complaints had already been received. The Ohlstadt community had an interest in the path, but they were not allowed to do anything either, it was not possible to mark the path." The Weilheim section explained in an angry letter to the main committee of the German-Austrian Alpine Association that the path led through a swampy raised bog, so that around 2000 marks would be needed to repair it, which the section could not afford. Furthermore, the complainant is obviously not innocent of his mishap: it is impractical for a tourist without any knowledge of the mountains to go hiking in the Alps in the late autumn afternoon, especially with young people who are not familiar with the mountains. Colored markings would be pointless in the face of the approaching darkness. A teacher can be expected to be able to find the way using a map, otherwise he would be better off just taking his charges for a walk in the city park or on the country road during the day.
