Groot - Highest Point in the Canton of Thurgau With the Groot (991.1 m), we head to the highest elevation in the Canton of Thurgau: literally "the Top of Mostindien." Interestingly, about 10 m further on lies the so-called ridge, which is also the highest point of the elevation. It rises 5 m higher than the Groot and is located entirely in Mosnang, or rather, in the Canton of St. Gallen. On this tour, we explore the idyllic Tössberg region.

In winter, the great paths offer a little more views and are therefore worthwhile.

For a moment I thought it would be like the Taneggergrat, which is also in the area, but it was only steep on one side. The paths are also narrow, but still no comparison
